(2) 29,79
(3) 39,69

Answer 1

Answer:

OPTION 2

Explanation:

Either learn the periodic table so the group contains copper(29) ,silver(47) and gold (79) or as you know that that copper is in fourth period so while moving from fourth to fifth period 18 is added

while moving from fifth to sixth period 32 is added as the periodicity is of 2,8 ,18,18 and 32 elements

.but better to learn periodic table as due to lanthanoids and actinoids there is variation in this trend
