Why is xenon called Stranger gas?
Complete answer: As Xenon belongs to a noble gas group where elements are very unreactive. But Xenon reacts with some elements to form new compounds. This unique property of Xenon makes it peculiar and that is why it behaves in a different manner. Hence, this is the reason why it is known as stranger gas.

This is usually a tube filled with xenon gas, with electrodes at each end and a metal trigger plate at the middle of the tube.
What is the oxidation state of an atom?
The oxidation state of an atom is a measure of the degree of oxidation of an atom. It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge.
What is density in science?
Density is the mass of a substance that would fill 1 cm 3 at room temperature. Relative atomic mass. The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus.
How are elements organized into blocks?
Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The number of protons in an atom.

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.
What are the horizontal rows on the periodic table called?
The horizontal rows on the periodic table are known as Periods.
Why is period 1 the shortest period?
Period 1 of the periodic table is given the name shortest period because there are only two elements in period 1.
Why are period 4 and period 5 called long periods?
Period 4 and period 5 are given the name long periods of the periodic table because there are 18 elements in these periods. The elements of the long periods are shown in tables below.

Periods in Periodic table: The periods are the horizontal rows on a Periodic table. There are 7 horizontal rows on Periodic table. Hence there are total 7 periods on the Periodic table.
Why is period 2 called a short period?
Period 2 and period 3 of the periodic table are named as the short period because there are 8 elements in these periods.
Which period has the longest period?
Period 6 and 7: Longest period. Period 5 and period 6 are named as longest periods of the periodic table because there are 32 elements in these periods. The elements of the longest periods are shown in tables below.
How many energy shells does period 2 have?

What is the most abundant element in the atmosphere?
Helium is the most abundant element in the earth after hydrogen. And helium is present in the air while other noble gases are found in earth’s atmosphere. So, the percentage of noble gases in air is as He (0.0005%), Ar (0.94%), Xe (0.00001%), Ne (0.015%), Kr (0.0001%).
What is the group of gases that cannot react with other elements?
They cannot not react with other elements therefore these are called the inert or unreactive gases. However, some noble gases can actually react to form certain compounds, that’s why this group is referred to as noble gases.
Why does the atomic size of a group increase as we go down?
As we go down the group atomic size will be increases due to increasing in number of shells.
Is a noble gas colorless?
All the noble gases are colorless, odorless, tasteless and monoatomic that means they exist as single atoms.
Is helium a compound?
These are almost chemically inert but form few compounds also. For example- compounds of helium are called helides. These are formed at low pressure in presence of Mercury (Hg), Tungsten (W) etc. By sparking He. For example:- HgHe2, HgHe10, FeHe etc. The compounds are formed due to adsorption of He on metal surface. So, these are not considered as true compounds.
