Let us take the example of Bismuth. It's atomic number is 83 . Then how do we identify whether its atomic sixe increases or decreases?

Solution

The size of an isolated atom can't be measured because we can't determine the location of the electrons that surround the nucleus.
But we can compare the size of atom by either comparing with periods or groups . And we can also calculate the radii of ionic mettalic or covalent molecules. So by looking the periodic table and following the trend we can calculate all those .

As we know that if size of atomic radii increases, I.E decreases. But why it is said in a random topic that I.E increases down the group?

In my Pearson book it is written that Atmoic radius decreases due to increase in atomic number

Also

Ionization energy increases from top to bottom of a group since the atomic size decreases due to increase in atomic number

Please explain sir

Is atomic mass the sum of the number or mass of protons and neutrons.

If it is sum of number , then why is it called atomic MASS

And if it is sum of mass then how do we know the no of neutrons and proton sin the atom.
