After transferring the electron, which ion is negatively charged? Why is the ion negatively charged? Write the symbol for the negative ion: -

After transferring an electron, the ion that lost an electron, assuming it was neutral before, would be a cation. The atom that gained an electron would be an anion.

The ion is negatively charged because it has gained an ion, adding a negative charge to the atom's neutral state. Because it has no protons to cancel the charge, it gains 1 negative charge, making it an anion.

The symbol for a negative ion would be (-) and a positive would be (+)

For example, when oxygen is an ion, here's how it would look: O2-

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: )
