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

Periodic Table - Electronegativity

On moving from left to right in a period in the periodic table, the size of the atom.

Moving from right to left in a periodic table, the atomic size is :

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

(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?

Explain the following according to Modern periodic table: ltbr. (a) Electronegativity of elements increase on moving from left to right in a paeiod. (b) Ionisation enthalpy decrease in a group from top to bottom.
