Question

5 multiple choice 3 points a sodium atom loses an electron. it now has a net charge of: +2 -1 zero +1

Explanation:

Step1: Analyze the charge of a neutral sodium atom

A neutral atom has equal number of protons and electrons. Sodium has 11 protons (positive charge) and 11 electrons (negative charge). The net charge is \(11 - 11=0\).

Step2: Consider the effect of losing an electron

When a sodium atom loses 1 electron, the number of protons is still 11, and the number of electrons becomes \(11 - 1 = 10\). The net charge is \(11-10 = + 1\) (since charge of a proton is \(+1\) and charge of an electron is \(-1\)).

Answer:

+1
