General Squaring-From Left To Right

(a) How does the size of atoms (atomic size) generally vary in ging 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?

Atomic radius increases while going from left to right within a period.

Electronegativity increases while going from left to right within a period.

In the periodic table from left to right in a period, the atomic volume

Explain the following : (i) Nonmetallic character increases in going from left to right in a period . (ii) The basic nature of oxides of the elements decreases in going from left to right in period.
