So elements can obviously be identified by their name, but they also can be identified by their atomic number, which is going to be the number of protons and the nucleus.
00:10
And so here we're going to name all these elements, we're going to name the atomic number.
00:14
And so for ge, which is also known as germanium, similar to the country, is going to have 32 protons in its nucleus.
00:21
So the atomic number is going to be 32.
00:23
Zinc, also known as zn, for its atomic symbol, is going to have 30 protons in its nucleus.
00:30
So its atomic number is going to be 30.
00:33
Cr, also known as chromium, is going to have 24 protons in its nucleus.
00:38
So its atomic number is going to be 24.
00:41
Thompson, also known as w for its atomic symbol.
00:46
Atomic number is 74, or it has 74 protons in its nucleus...
