The nucleus of a helium atom is composed of 2 protons and 2 neutrons (the atomic number is 2 and the mass number is 4).
Protons have a relative charge of +1 and neutrons a relative charge of 0, so to work out the charge we do number of protons multiplied by the charge of the proton.
The charge on a proton is 1.60 * 10^-19
So charge= (1.60 * 10^-19) * 2 = 3.2 * 10^'19
Hope this helps :)

What is aluminum overall charge of an atom?
The neutral atom hasn't a charge.
Why the overall charge of the oxygen atom is zero?
The overall charge of any atom is 0. This is because the overall charge is number of protons - number of electrons. For every atom the number of electrons is equal to the number of protons so it is 0.
The overall charge of the oxygen atom is?
Zero
What is the charge of lithium atom after forming ion?
A lithium ion has a positive overall charge.
What is the overall charge of an atom with 3 extra electrons?
ozone
What is the overall charge of helium atom?
The overall charge on He is 0. It is a noble element.
Does the helium atom hold an overall charge?
Not normally - but it can be ionized.
Does helium of a charge?
Helium atom has no charge as all atoms are electrically neutral. But the nuclear charge of helium is 2 as it has 2 protons in its nucleus.
What is aluminum overall charge of an atom?
The neutral atom hasn't a charge.
What is the ion charge of a helium atom Is it plus 1?
Helium does not form ion.
What is the general overall charge of an atom?
A neutral atom hasn't an electrical charge.
What is the overall charge of the oxygen atom?
The overall charge of any atom is 0. This is because the overall charge is number of protons - number of electrons. For every atom the number of electrons is equal to the number of protons so it is 0.
What is an atom that has no overall charge is?
A: Neutron
What is the overall electric charge of an atom?
The overall electrical charge of an atom is the difference between the number of protons and the number of electrons. In the neutral state, non-ionized, they match each other. Lose or gain an electron, and the balance is upset, creating an ion. An alpha particle, for instance, is a helium atom without the two normally present electrons, giving it a charge of +2. The symbol for this is 24He2+.
Why the overall charge of the oxygen atom is zero?
The overall charge of any atom is 0. This is because the overall charge is number of protons - number of electrons. For every atom the number of electrons is equal to the number of protons so it is 0.
What is the overall charge on any atom?
An atom is neutral, and therefore has an overall charge of zero. If an atom either loses or gains electrons through a chemical reaction, or loses protons through radioactive decay, so that it then has an overall charge, it is no longer considered to be an atom but is classified as an ion.
The overall charge of the oxygen atom is?
Zero
