The atomic number the the number of protons and therefore the total positive charge in the nucleus. So the the element with the atomic number 82 has more protons and a greater nuclear charge then the atomic number of 81. More protons can mean many different things such as a smaller radius, greater first ionisation energy or greater electronegativity.
Argon is a gas element. atomic number of it is 18.

The atomic number of an element equals the number of protons in the element.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
Thallium is a meta element. Atomic number of it is 81.
one more proton, and electron
one more proton, and electron
Thallium is a meta element. Atomic mass of it is 204. Atomic number of it is 81.
Titanium is a metal element. Atomic number of it is 81.
