Question

the electrical charge of the nucleus of an atom is +12. how many electrons does the atom have in its neutral state?
6
12
18
24

Explanation:

Step1: Recall atomic - charge principle

In a neutral atom, the number of protons (which give the positive charge to the nucleus) equals the number of electrons (which have a negative charge).

Step2: Identify proton number

The charge of the nucleus is + 12, which means there are 12 protons.

Step3: Determine electron number

Since the atom is neutral, the number of electrons is equal to the number of protons. So, there are 12 electrons.

Answer:

B. 12
