How do you find the atomic number in the periodic table?

Answer 1

The atomic number of an element is the number of protons contained within the nucleus of an atom of that particular element. Since each element has a different number of protons, elements can be placed into a table based on the number of these particles.

Answer 2

Depending on what type of Periodic Table you are using, it may be different. But if you are using a good one, there should be a name, a symbolic letter, and at least two numbers on it. The one I am using, for instance, says:

1

Hydrogen

H

1.0041

The first number (the 1) is the atomic number.

Some periodic tables might even neglect the Atomic Number. So like I said, it really depends on which edition you are using.

Answer 3

The atomic number of an element is the number of protons in its nucleus, which is also the same as the number of electrons in a neutral atom. You can find the atomic number of an element on the periodic table, which is usually located above or below the chemical symbol for that element.
