So when you look at the periodic table of elements, you can tell a lot about an element, simply just looking at its location on the periodic table.
00:09
And so in particular, we're going to be looking about column placement and how that corresponds to what you could tell about the element.
00:16
And so for this particular problem, we're going to be looking at the elements here on the right.
00:19
And we're going to just look at what column they're in and tell us, this is going to tell us what family or group that they're in.
00:26
And so if i take a look here on the right, we have iodine.
00:29
And so for iodine, i'm going to be looking for the letter i, which is going to be in column 17.
00:35
And column 17 is actually the halogens.
00:38
So iodine is going to be a halogen.
00:42
Calcium, also known as ca, is going to be in my second column.
00:47
And this second column is going to be echeline earth metals.
00:51
So ca is going to be acolyne earth metals.
00:57
I'm not going to write earth metals, but this is going to be acolyne earth metals.
01:01
And a, also known as sodium, is going to be in your first column right here...
