Question

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

Answer 1

The new charge is +2

Step-by-step 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
