element no 14 is silicon element no 18 is argon element no 22 is titanium
18+14+14-22=24
2:18-2:22
22
14+16+16+18+22= 4(16)+22= 64+22= 86 86/5= 17.2 17.2
Group 7 contains 5 elements, group 14 contains 6 elements, and group 18 contains 7 elements.
The GCF is 2.
The GCF is 1.
It is: 14+15+22+21 = 72/4 => 18 which is the mean average
if your 18+ he might but 14 is too young for someone over 18
the answer is 20 since you have to find the distance between 18 and 22
16
The GCF is 2.
