1. Rank each of the following in order of INCREASING atomic radius
a F, K, Br
b. Mg. Na, Cs
c. Os, Ni, Fe

2. Rank each of the following in order of DECREASING atomic radius

A. CI, Br, Ga
B. Ne, Rn, Pb
C. Ca, Rb, C

Respuesta :

STARTING FROM SMALLEST TO BIGGEST
1 a. F , Br , k
b. Mg , Na , Cs
c. Ni , Fe , Os
Explanation: down the group , atomic radius increases . And across the group , atomic radius decreases . REFER PERIODIC TABLE TO SEE WHERE THE ELEMENTS ARE SITUATED
