Element A has 9 protons. Element B has 8 more protons than A. Which statement about element B is correct? * 2 points B has more electron shells than A B has more electrons in its outer shell than A B has more valence electrons than A All of the above

A) B has more electron shells then A

Explanation:

Element A is flourine

Element B is chlorine

Chlorine has three electron shells and flourine only has 2 electron shells (on Bohr model)

Chlorine's outer shell has 7 electrons and so does flourines outer shell(on bohr model)

Sense Answer A is correct and Answer B is wrong, common snese will tell you that D is wrong sense B is wrong, and sense D is wrong that means only one is right and sense A is correct it makes C wrong
