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.
Chromium is a metal element. Atomic mass of it is 52.
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 :-)
There isn't an element with the atomic number 202 because the known elements in the periodic table have atomic numbers up to 118, which is Oganesson. Any element with an atomic number higher than 118 would be highly unstable and would not exist naturally.
The atomic number of a chemical element is equivalent to the number of protons and electrons, in the neutral state.
No. It is a Atomic element because it exist in nature with single atoms as their basic unit.

This element doesn't exist. Check the spelling.

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.
Ununhexium Provisional name for the synthetic element not yet proven to exist
The atomic number of a chemical element is equivalent to the number of protons and electrons, in the neutral state.
