Which of these is an example of an atom that has no charge? we have four of them, and we're going to go through them.
00:08
Okay, so an atom has three types of subatomic particle.
00:12
The proton, the electron, and the neutron.
00:15
So proton, neutron, electron.
00:18
I put them like this because the proton and the neutron are in the nucleus.
00:22
The electrons, they're not in the nucleus, they're orbiting around it.
00:26
So a proton has a mass of one, and a charge of plus one.
00:30
A neutron has a mass of 1 and a charge of 0, it's neutral, and electron has a mass of nearly 0, it's really tiny, and a charge of minus 1.
00:44
So, proton is mass 1, charge plus 1, neutron is mass 1, charge 0, electron is mass basically 0, charge minus 1.
00:57
Okay, so the charge, obviously the neutrons aren't going to implement a 0, the charge.
01:03
The charge is going to be the protons against the electrons...
