Question

What is periodic property?how is the following properties vary in a group and in a period explain? ,Atomic radius,electron gain enthalpy,electronagativity

Answer 1

Answer:

Group : Atomic radii increases from top to bottom in a group, the atomic number of the element increases. Period : Atomic radii of elements decrease across period from left to right. As electrons enter into the same main shell. ... Group : Electronegativity values of elements decreases as we go down in a group.
