Hello!

I do not have all ten listed out, however I can show you how to find out. First things first understand what the numbers mean on the table of elements. The number at the top is the atomic number. This represents how many protons an element has. This is also how many neutrons it has, because there is always the same number of protons and neutrons. The number at the bottom is the atomic mass. This is how much the atom weighs. To find the first 10 look for the elements with atomic numbers 1-10. It should be easy. I’ll give you the first one for example.

Hydrogen is the element with a atomic number of 1. Its atoms contain

-1 proton

- 1 neutron

-1 electron (also note the amount of electrons is equal to the amount of protons and neutrons)

Hydrogens atomic mass is (1.00784 u)

Lastly the symbol for hydrogen is (H)

Hope this helps!!!
