(a) How does the size of atoms (atomic size) generally vary in going from left to right in a period of the periodic table? Why does it vary this way?
(b) What happens to the metallic character of the elements as we move from left to right in a period of the periodic table?

Answer:
A. Atomic size gradually decreases from left to right across a period of elements. This is because, within a period or family of elements, all electrons are added to the same shell. ... The valence electrons are held closer towards the nucleus of the atom. As a result, the atomic radius decreases.
B.
Metallic character decreases as you move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down an element group in the periodic table
