Question

chemists use integers to express the electrical charge of particles. a proton has a charge of +1, an electron has a charge of -1, and a neutron has no charge. what integer represents the total charge of 4 protons?

Explanation:

Step1: Determine the charge of one proton

The charge of one proton is \(+ 1\).

Step2: Calculate the total charge of 4 protons

Since there are 4 protons, we use multiplication. The total charge \(Q=4\times(+1)\).
Using the rule of multiplying a positive number by a positive number: \(4\times(+1) = + 4\) (or simply \(4\)).

Answer:

\(4\)
