Based on the electron configuration of the two
atoms, predict the ratio of metal cationic (+) atom
to nonmetal anionic (-) atom in the compound.
Sodium 1s22s²2p 3s
Bromine 1s22s22p3s23p64523d104p5
A. 1:1
B. 1:2
C. 2:1
D. 3:1

the millers tale is the answer.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
