I've recreated the chart, and the first thing we need to do is take our symbol and take a look at what it means.
00:09
So we're going to look at the vanadium one, because, well, it's the only actual symbol we have written already.
00:15
The rest we're going to have to figure out.
00:19
Now, the letter obviously is what element this is.
00:21
V is vanadium, which is right here.
00:24
Okay.
00:25
That 23 at the bottom, that is your atomic number.
00:31
That is also on the periodic table, right? and it indicates which element it is.
00:39
Okay, vanadium is always 23.
00:40
Hydrogen is one.
00:42
Helium is 2.
00:42
Lithium is 3.
00:44
And its direct correlation to the atom is it tells you how many protons you've got.
00:50
So right off the bat, we know that this element has 23 protons.
00:55
So we can go ahead and put that in.
00:59
Now, the top number, the 51, that number is not.
01:05
On the periodic table.
01:07
People very commonly mistake it for the molecular weight or the molar mass atomic weight.
01:13
There's a lot of names for it.
01:15
But the number that has decimal points after it, so the 50 .94 for vanadium.
01:21
They commonly mistake it.
01:23
They are very similar, but they're not the same thing.
01:26
This is called the mass number up on the edge of the screen where it just does not like to let me write for some reason.
01:35
There we go.
01:35
That's the mass number.
01:39
It represents your protons plus your neutrons.
01:45
So we know that our protons and neutrons are 51.
01:48
Okay, so that makes it very easy to figure out the neutrons, right? because we know that 51 equals protons plus neutrons for this element.
02:00
And we just figured out that the lower number 23 is our protons.
02:03
So we've got 23 protons.
02:07
So if we just do 51 minus 23, we're going to to get our neutrons, which i believe is 28.
02:20
All right.
02:21
So we can plug that in right there.
02:22
It's 28.
02:26
For these, all of these are just atoms.
02:30
They're not ions or anything like that.
02:32
They don't have any charges.
02:33
They're just neutral.
02:34
So that means that the number of protons equals the number of electrons.
02:38
If this had a charge, you would see it in like a top right corner.
02:43
It would look like an exponent.
02:44
It would be like plus one, plus two, or minus two or something like that.
02:48
All right.
02:49
These are all neutral, so we're not going to have to worry about that.
02:52
Which means our positive protons equals our negative electrons.
02:57
So if we have 23 protons, we also have 23 electrons.
03:03
Okay.
03:04
And the name of this element is phonadium.
03:09
If you don't have a periodic table that has the names on it, i know some books, there's always a periodic table in the front cover of books, but some of them have the names, some of them just have symbols.
03:20
I recommend grabbing a periodic table that has the names because you really need to get used to those if you're not super comfortable with it already.
03:28
You can google them...
