(NH₄)₂[CoF₄]

2(+1) + x + 4(-1) = 0
2 + x - 4 = 0
x - 2 = 0
x = +2

Therefore the oxidation state of Cobalt is +2

JUSTASTUDENT2: thanks for your help : )
siril: welcome
JUSTASTUDENT2: i need your help again
siril: ok
siril: ask your question
JUSTASTUDENT2: what is the co-ordination number of that question

siril: leaving the central atom of course
