While going left to right in a period in the periodic table , how does ionisation energy change ?

(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?

In second period of the periodic table, ionisation energy follows the order:

On moving from left to right across a period in the periodic table the metallic character

On moving from left to right across a period in the periodic table the metallic character

On going from right to left in a period in the periodic table the electronegativity of the elements:

On going from right to left in a period in the periodic table the electronegativity of the elements:

On going from right to left in a period in the periodic table the electronegativity of the elements

On moving from left to right across a period in the periodic table, the metallic character………..
