5. Which statement describes the charge of an electron and the charge of a proton?
A) An electron and a proton both have a charge of
+1.
B) An electron and a proton both have a charge of
-1.
C) An electron has a charge of +1, and a proton has
a charge of -1
D) An electron has a charge of -1, and a proton has
a charge of +1.

Explanation:

Electrons and protons are both subatomic particles in an atom.

First, analyze both.

Electron

Proton

So, we see that the electron has a charge of -1 and the proton has a charge of +1. The correct answer must be choice D.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
