Hi there.
00:03
In this question, we are trying to identify the false statement about subatomic particles.
00:10
And the subatomic particles of interest here are the protons, neutrons, and electrons.
00:18
So let's look at each of these statements, one at a time.
00:22
The first one says the charge on electrons and protons are equal in magnitude, but opposite in sign.
00:29
That is true.
00:30
Protons are positively charged, while electrons have a charge of the same.
00:35
Same magnitude, but it's negative.
00:39
So first statement is correct or true.
00:42
Second statement, the mass of a proton and a neutron are approximately the same.
00:47
That is also true.
00:49
They are much more massive than an electron, but they are very close in mass to each other.
00:56
The next one says the mass of a proton is approximately one gram.
01:01
Ooh, that's a big false.
01:04
Just think about it.

If you had an atom of, say, mercury...
