Question

Complete the chemical change. Na → Na+

a.)2e-
b.)proton
c.)1e-

Answer 1

C) 1e- is the answer because you need that in order to balance the charges

Answer 2

The answer is c) 1e-

Step-by-step explanation:

The chemical change is the loss of 1 electron (1 e-) in 1 atom of sodium (Na) to give a sodium cation (Na⁺). You have to put the electron in the cation side of the equation. In this way, the overall process is electrically neutral (1 positive charge is neutralized by 1 negative charge and the other side has not charges):

Na → Na⁺ + 1 e-
