Let's take a look at the nucleus of the atom and what surrounds it and try to figure out whether particular statements are true or false.
00:14
And so if we're going to start taking a look at the nucleus, does it have the most mass in the atom? okay, yes, okay, most mass is in the nucleus.
00:35
The nucleus contains our protons plus neutrons.
00:40
Remember the electrons really don't have much mass at all.
00:43
But does the nucleus contain the most volume? no.
00:49
Okay? the nucleus is very small compared to the size of the atom itself because the electrons orbit far away from the nucleus.
01:05
So even though the first part of the statement is true, the second part of the statement is false, making obviously the combination then false.
01:18
And does every atom of a given element have the same number of protons? yes, okay? because remember the atomic number is the number of protons, and that identifies the element...
