An atom has protons, neutrons and electrons. The charge of proton is ‘+1’, the charge of a neutron is ‘0’ and the charge of an electron is ‘ -1’. If the total charge of an atom is the sum of all the charges of protons, neutrons and electrons, find out the total charge of an atom which has 2 protons, 2 neutrons and 2 electrons.

Step-by-step explanation:
Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Hope this will help you buddy....
Have a nice day ahead
