Calcium and bromine have formed a bond. leading up to this, calcium gave up electrons. it was a(n)

negative ion
shared ion
positive ion
neutral atom

I think the correct answer from the choices listed above is the third option. Calcium and bromine have formed a bond. Leading up to this, calcium gave up electrons. It was a positive ion. Giving up electrons would make an atom more positive. Hope this answers the question. Have a nice day.

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.

                             

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
