Question 9 (1 point)

As you move down a group of elements (family), the number of valence electrons

Question 9 options:

increases and then decreases.

stays the same.

increases.

aluminum

calcium

potassium

Explanation / Answer

1) Potassium element would behave most like sodium. Because these two belonging to same group that is I group.

2) Order of increasing size is aluminum ion < magnesium ion < Poatassium ion

3) The elements Cl, O, F have tendency to gain electrons.

4) F, Cl, Br , I

5) second ionization of sodium. Na+(g) ----> Na2+(g) + e-

6.) Aming the given atoms F has the smallest atomic radius.

7) N ahs the greatest ionization energy as it has half-filled configuration.

8) Cs has lowest ionization energy as it has lareger size.

9) The elements in same group have same number of valence electrons.

answer is stays the same
