Hi there.
00:03
This question is asking about all of the atoms of an element.
00:11
And it wants to know what is the same.
00:15
Well, i'm not sure if the answer choices copied correctly.
00:20
Because for a, i have protons.
00:22
That's cool.
00:23
For b, neutrons.
00:28
That's awesome.
00:30
C, we have electrons.
00:36
But d, we also only have electrons.
00:43
So i am not sure if we're one of these c or d possibly should say electrons and protons.
00:55
So that's kind of a question mark here.
00:58
Because when we talk about an atom, the atomic number of any element on the periodic table is equal to the number of protons in the nucleus of every atom of that type of element.
01:17
So every atom of an element is always going to have the same number of protons.
01:24
So that is definitely one of our answers.
01:27
However, we are calling these atoms, and by definition, atoms are neutral, because they're not ions.
01:37
If they have a charge, we call them ions...
