Do you own CA work!!
Beacause of electronic configuration (M.O.T)
Elements in group VIA (6A) also called group 16.
It is alternatively called the Carbon family.
The elements in group 6a (16) have six valence electrons. The valence electron configuration is Xs2Xp4 , where X is the main energy level (period number).

Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
2a-6a+9-4a+9
If you mean -2a+6a then it simplifies to 4a
6a
The Group 6A elements are oxygen, sulfur, selenium, tellurium and polonium. The number of valence electrons in Group 6A is 6.
6a to the second power minus 8ab + 2a
6a2
5a-20+2a = 6a-11 5a+2a-6a = 20-11 1a = 9 a = 9
Basically any element with a positive atomic number because all the electrons are paired. Ex: Group 2A, Group 4A, group 6A, and group 8A. the ions would all be paramagnetic though.
I guess you mean: 2a^2+6a Well in this case you take 2a out of the bracket and then you're left with a+3 inside. 2a(a+3a)
6a squared-8ab+2a factor completely and check mentally
