The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.
Interesting ... At first I thought, this element does not exist. But then I looked it up and to my amazement found out its an artificially generated element with the atomic number 111 :-)
The atomic number of a chemical element is equivalent to the number of protons and electrons, in the neutral state.
No. the atomic number tells you the number of protons it has.
The number of protons and electrons of the atom in a neutral state.

Helium has completely filled orbitals, is stable and is not reactive. Hence they exist as mono atomic
Atomic number helps in determining the valence state of an element.
