According to the five elements theory, everything in nature is made up of five elements: Earth, Water, Fire, Air, and Space.
Why 7th period is not longest period?
7th period is not the longest as it contains less than 32 elements.
What is the period of 7?
The seventh period contains 32 elements, tied for the most with period 6, beginning with francium and ending with oganesson, the heaviest element currently discovered. As a rule, period 7 elements fill their 7s shells first, then their 5f, 6d, and 7p shells in that order, but there are exceptions, such as uranium.

Does the Modern Periodic Table Change? If So, How and Who Does That?
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack).
What is the CIAAW?
Since 1899 the IUPAC Commission on Isotopic Abundances and Atomic Weights ( CIAAW) has been evaluating atomic weights and abundances. For example, Carbon had an atomic weight of 12.00 in 1902 but today it is [12.0096, 12.0116]! Times sure have changed as the source of the sample will determine the value.
What is PubChem working with?
PubChem is working with IUPAC to help make information about the elements and the periodic table machine-readable.
Who is responsible for deciding what needs to be changed?
While much of what is in the periodic table is stable and unlikely to change, the IUPAC organization is responsible for deciding what needs to be changed. They have created criteria for what constitutes the discovery of a new element.
Can periodic table games be used for grade?
The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.
Who created the periodic table?
The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train.
Did Mendeleev's predictions get dismissed?
There were plenty of skeptics and it took years to gain international acceptance, but once newly-discovered elements matched the ones that Mendeleev predicted, his patterns could not be dismissed. In addition, some of the properties that he "fudged" were later recalculated and found to be much closer to his predictions.
How to read the periodic table?
To read the periodic table, start at the top left with the elements with the lowest atomic numbers, which tells you how many protons each atom has. Then, as you move right across the chart, make note that the atomic weight, shown at the bottom of the square, also increases.
Why does the atomic mass increase as you move down the table?
The atomic mass increases as you move across or down the table because the mass is calculated by adding up the protons and neutrons in each element’s atom. The number of protons increases with each element, which means the weight goes up, as well.
How are elements ordered?
The elements are ordered by their atomic numbers, which increase as you move across and down the periodic table. The atomic number is how many protons the element’s atom possesses. You’ll also notice that each element’s atomic mass increases as you move across the table.
Why does the periodic table have gaps?
Since elements don’t always fall neatly into groupings as they increase in number, the periodic table contains gaps. For example, the first 3 rows have gaps, as the Transition Metals don’t appear on the table until atomic number 21.
How does wikihow mark an article as reader approved?
wikiHow marks an article as reader-approved once it receives enough positive feedback. In this case, 85% of readers who voted found the article helpful, earning it our reader-approved status.
Why do most elements have atomic weights that include decimals?
Because the weights are averaged, most elements will have atomic weights that include decimals.
What are the gaps in the table?
Since the elements are also arranged by group, you will see gaps on the table. For example, the first row contains Hydrogen, which has an atomic number of 1, and Helium, which has an atomic number of 2. However, they are at opposite ends of the table, as they are in different groups.
