Answer 1

Answer:

Periodic properties :- In the periodic table after a particular periodical time the chemical and physical properties of every elements are as same as their 9th number of element thus properties of the periodic table is called periodic property.

(a) atomic radios - when we go down in the table the radios of element are increase because the number of cells are increase .

(b) the ionization energy decrease when we go down.

(c) electronic affinity is decrease when we go down

(d) the electronegativity is also decrease when we go down.

Now , I am hoping you that u will easily can do the else problems.
