Question

if we say that atomic size decreases with increases in the atomic number so, how can we say that? if we take any atom the number of electrons is equal to the number of protons so, the size of every atom remains constant of every atom.

ATOMIC NUMBER=NUMBER OF PROTONS AND NUMBER OF ELECTRONS .

Answer 1

Answer:

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Answer 2

Answer:

yes you are right in your second statement!

Explanation:

You know every atom is differentiated with atomic number and its implies the properties of that element.

every element is arranged in periodic table in such a way that one element has a successive atomic number from other element but only one of its kind.

so it solely matters on atomic number to determine probably every property of that element including size!
