So let's define some chemistry terms today.
00:03
But before i start, i always recommend students to pause the video, do it themselves, and then come back to see if they got it right or not.
00:11
That is the true way of knowing if you fully understand this topic.
00:14
So first we want to identify a molecule and compare that to an ion, right? a molecule is one important component about it is that it is electrically, right? that is the most important part because ion, right? have a charge.
00:37
Molecules do not.
00:39
And group of two or more.
00:52
So atoms would be, okay, let's look at the example of water.
00:57
So if we had oxygen here, right? oxygen.
01:01
That would just be the atom, but water has two hydrogens as well.
01:07
So that makes it a molecule.
01:09
So molecules electrically neutral and has a group of two or more atoms.
01:13
That can be held together by chemical bonds.
01:16
And then ion, on the other hand, this has a charge because the atom or molecule has lost or gained an electron.
01:33
An example could be an a plus.
01:36
This is an ion because it has, the plus here indicates that the sodium atom has lost an electron, right? now moving on to the difference.
01:48
Between covalent bonding and ionic bonding.
01:51
So for covalent bonding, the species, let's say, or what is involved in covalent bonding is atoms...
