Question

What is the 23 element on the periodic table? What does 23 stand for?

Answer 1

If `Z=23`, the element is vanadium.............

Explanation:

`Z` is the so-called `"atomic number"`, which is the number of protons, fundamental, massive, positively charged particles in the element's nucleus. This number defines the identity of the nucleus: `Z=1`, the element is hydrogen; `Z=2`, the element is helium;...............`Z=23`, the element is vanadium.........

You shouldn't have to remember these numbers, because for every examination in chemistry and physics you ever sit, you should be issued with a copy of the Periodic Table, which lists the atomic number of the 100 or so elements, along with details of their atomic mass. Of course, you have to be able to use the Table......
