1. Al-electronic conf=2,8,3 so period no is 3 and group 3
2. Mg-electronin conf =2,8,2 so period no is 3 and group 2
3. F-electronic conf=2,8 so period no is 2 and group is 7
4.Ar-electronic conf=2,8,8 so period is 3 and group is 0 becaise it is a noble gas
2. Mg-electronin conf =2,8,2 so period no is 3 and group 2
3. F-electronic conf=2,8 so period no is 2 and group is 7
4.Ar-electronic conf=2,8,8 so period is 3 and group is 0 becaise it is a noble gas
