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
- As we go from left to right across the period atomic size decreases gradually atomic number increases. The proton and electron number increases and due to the large positive charges on nucleus electron has been pulled inside more closer and thus size of the atom decreases.
- The metallic character of the element decreases as we move from left to right in a
