To understand what are monatomic cat ions, monotomic anions, polyatomic cat ions and polyatomic anions.
00:11
First we are going to go over the notion cat ions and anions.
00:17
So cat ion is when a neutral item lose one or more electrons.
00:24
It will become a cat ion.
00:26
So when a neutral item lose, one or more electrons.
00:44
This ion is going to have a net positive charge because they have more protons than electrons.
00:51
Remember a neutral item has the same number of protons and the same number of electrons.
00:58
It's just their atomic number.
01:00
The atomic number represents the protons and electrons they have.
01:04
So for instance, a sodium atom, an a, which can can give up an electron to become a sodium a sodium a plus.
01:18
Now what is anion? anion is an ion that has a negative charge due to an increasing the number of electrons.
01:29
So they gain electrons...
