: Tricks to Remember the First 30 Elements in Periodic Table
Is it necessary to memorize the periodic table?
Finding patterns and origin –
Keep in mind the Latin names – The Latin names are difficult to keep in mind and thus can be made as milestones that you would remember at any point in time. Keep in mind the difference between the names You can use flashcards to memorize the periodic table.
Memorizing the periodic table is important because it is organized and gives a lot of information about elements. Also, it makes students understand how elements relate to one another.
It is used to predict the properties of every element. Groups and periods give information about the elements sharing similar characteristics. The periodic table provides significant information which can be used in,
These were some tricks and tips that can be used to remember and understand the Periodic table. To learn more about the Periodic Table and the various elements in it visit us at byjus.com or download our BYJU’S – The Learning App.
Why do the elements stop at 118?
The modern periodic table has approximately 118 elements because till now only 118 elements that are stable enough to observe.
Why are there no elements past 118?
History – Heavier elements beyond the actinides were first proposed to exist as early as 1895, when the Danish chemist Hans Peter Jørgen Julius Thomsen predicted that thorium and uranium formed part of a 32-element period which would end at a chemically inactive element with atomic weight 292 (not far from the 294 known today for the first and only discovered isotope of oganesson ).
- In 1913, the Swedish physicist Johannes Rydberg similarly predicted that the next noble gas after radon would have atomic number 118, and purely formally derived even heavier congeners of radon at Z = 168, 218, 290, 362, and 460, exactly where the Aufbau principle would predict them to be.
- Niels Bohr predicted in 1922 the electronic structure of this next noble gas at Z = 118, and suggested that the reason why elements beyond uranium were not seen in nature was because they were too unstable.
The German physicist and engineer Richard Swinne published a review paper in 1926 containing predictions on the transuranic elements (he may have coined the term) in which he anticipated modern predictions of an island of stability : he first hypothesised in 1914 that half-lives should not decrease strictly with atomic number, but suggested instead that there might be some longer-lived elements at Z = 98–102 and Z = 108–110, and speculated that such elements might exist in the Earth’s core, in iron meteorites, or in the ice caps of Greenland where they had been locked up from their supposed cosmic origin.
- By 1955, these elements were called superheavy elements.
- The first predictions on properties of undiscovered superheavy elements were made in 1957, when the concept of nuclear shells was first explored and an island of stability was theorised to exist around element 126.
- In 1967, more rigorous calculations were performed, and the island of stability was theorised to be centered at the then-undiscovered flerovium (element 114); this and other subsequent studies motivated many researchers to search for superheavy elements in nature or attempt to synthesize them at accelerators.
Many searches for superheavy elements were conducted in the 1970s, all with negative results. As of April 2022, synthesis has been attempted for every element up to and including unbiseptium ( Z = 127), except unbitrium ( Z = 123), with the heaviest successfully synthesized element being oganesson in 2002 and the most recent discovery being that of tennessine in 2010.
- As some superheavy elements were predicted to lie beyond the seven-period periodic table, an additional eighth period containing these elements was first proposed by Glenn T.
- Seaborg in 1969.
- This model continued the pattern in established elements and introduced a new g-block and superactinide series beginning at element 121, raising the number of elements in period 8 compared to known periods.
These early calculations failed to consider relativistic effects that break down periodic trends and render simple extrapolation impossible, however. In 1971, Fricke calculated the periodic table up to Z = 172, and discovered that some elements indeed had different properties that break the established pattern, and a 2010 calculation by Pekka Pyykkö also noted that several elements might behave differently than expected.
Why not memorize the periodic table?
Memorise the periodic table? No! The periodic table is the chemist’s alphabet, and we need to be very familiar with it. By putting the elements together in various combinations, as we do when we spell words, we can build our dictionary, containing all the substances in the universe. But just as you don’t learn the dictionary from cover to cover, students don’t need to memorise the order of the periodic table from left to right to use it effectively. My early-years daughter can ‘sing her ABC’, but this alone doesn’t make her a fluent reader, just as knowing the order of the elements by rote won’t help you to understand observations and make predictions.
- For that, you also need to understand why the elements are in that order.
- So I would argue that time in school, at least initially, should be focused on learning how and why the periodic table is put together as it is, rather than simply learning the elements’ order off by heart.
- That said, anyone who has ever watched a class of students search the periodic table blindly for even the most common elements would probably agree that a good familiarity with it is important.
Chemists need to know the symbols of common elements and have a feel for where they are located. But more importantly, they need to know what an element’s location tells them about its properties. Simply memorising their order off by heart won’t, in isolation, help with this.
- It’s important students memorise the order of elements in specific groups.
- For example, they’ll learn that sodium is a reactive alkali metal, with one electron in its outer shell, but potassium is an even more reactive group one metal.
- And they’ll find out that calcium behaves slightly differently, despite also being a reactive metal, partly because it’s in group two.
They’ll also become increasingly familiar with the halogens, and begin to remember where common elements like nitrogen, oxygen and carbon are located. But this is all learned in context. It would be of limited use if they didn’t understand why they’re found there.
- Remembering which elements are found within the same period is also useful, as is learning which elements are found within specific blocks.
- But I’d still argue that spending time reciting elements in order of increasing atomic number, with little knowledge of what this means, could be better spent.
- The analogy I use is speaking foreign languages.
When I learned German at school, I was told to just learn the different forms of ‘der’ by rote: der, die, das, den, die, das My dad (who taught German) was horrified, and said there was no point learning definite articles in isolation. He taught me instead to learn them in context: Der Mann, das Kind, mit dem Bus,
After all, it would be rather awkward to stop a conversation mid-sentence to work out which form of ‘der’ to use. I know that I ‘wohne in der Stadt’, but I ‘gehe in die Stadt’, because I’ve heard and used these in context. I also know where magnesium is located in the periodic table because I’ve used it many times before, but I don’t recite the elements in my head from hydrogen through to sodium, until I reach it.
Learning elements by rote has limited utility Having said all that, I do feel a little envious of my husband who knows the order of the periodic table by heart. I can see this heightened familiarity really helps him sometimes. But his knowledge of the elements’ order comes from frequent use over the years, so it gives him an additional degree of fluency in something he already uses a lot.
- Also, he still regularly refers to the periodic table, because it’s such a rich source of information.
- After all, even if you’d memorised all the elements’ atomic numbers, would you also memorise their mass numbers? To how many decimal places? So I have nothing against memorising the periodic table per se.
It’s important to increase your familiarity and confidence as a chemist. But learning elements by rote is not an end in itself, and has limited utility in isolation. Until they really understand how to use it, students’ precious time could be better spent elsewhere.
