Question

what integer represents the total charge of 4 protons?

Explanation:

Step1: Recall proton charge

A single proton has a charge of \( +1 \) (in elementary charge units).

Step2: Calculate total charge

For 4 protons, multiply the charge of one proton by 4: \( 4\times(+1)= +4 \).

Answer:

\( 4 \)
