What is the new charge of the sodium ion that has lost one electron? (Hint: think cation or anion) Your 0 +1 +2 -1

The new charge is +2

Explanation:

Sodium atom has 11 electrons (2, 8, 1)

sodium ion is cation and it will have 10 electrons after losing 1 electron (Na⁺), the charge is +1 because it needs to lose 1 electron to attain octet structure and become stable.

When this sodium ion loses 1 more electron, the new charge will be Na²⁺.

Thus, the new charge will be  +2

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
