Okay, here is a simple way to find the atomic number, Count the protons or if you want a more techical way. Take the total mass of the nucleus minus the mass of all the neutrons then divide the rest of the mass by the mass of one proton.

If an isotope of oxygen has 8 protons 10 neutrons and 8 electrons its mass number is?
This certain isotope of oxygen would have a mass of about 18 because electrons weigh almost nothing.
What is hydrogeon?
Hydrogen is an element having atomic number 1.It is the most plentiful element sen in stars.
What characteristics must a substance have in order to be classified as an element?
Each element has a specific number of protons in the nuclei of its atoms. This number is known as the atomic number for the element. For instance, the atomic number of hydrogen is one because it has a just one proton in its nucleus. The atomic number of oxygen is eight, again because it has eight protons in its nucleus. For a full summary see the link for the periodic table.
What is a collection of atoms called?
A large collection of neutral atoms with the same atomic number is a sample of an element. Elements include include lithium, hydrogen, neon, and oxygen. Note that different isotopes of elements exist; these are atoms with the same atomic number but having a different number of neutrons.
