Atoms contain with a positive charge, with a neutral charge, and with a negative charge. *

Protons with a positive charge

Neutrons with a neutral charge

Electrons with a negative charge

Explanation:

Atoms consist of 3 tiny particles: protons, neutrons, and electrons. Protons and neutrons are in the centre (nucleus) of the atom, the electrons are found around the nucleus.

The charges on the proton and the electrons are the same size, but opposite. Electrons possess a negative charge, and protons possess a positive charge. Because of this, they attract one another (opposites attract) and this is what holds the atom together. The neutrons have no charge, i.e. they are neutral

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.
