There is no element with atomic number 202. Element 118 is the largest made at the moment.
Mercury is a metal element. Mass number of it is 201.
The atomic number is the number of protons in an atom of an element.
When a mercury-202 nucleus is bombarded with a neutron and a proton is ejected, the resulting nucleus will have one less proton than the original mercury nucleus. Mercury (Hg) has an atomic number of 80, so after losing a proton, the new element formed will be gold (Au), which has an atomic number of 79. Thus, the reaction transforms mercury-202 into gold-201.
Atomic number = Number of protons
The atomic number of the element with the symbol Be (Beryllium) is 4.

Argon is a gas element. atomic number of it is 18.
The atomic number of the element with the symbol Be (Beryllium) is 4.
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
The element with the highest atomic number is Oganesson, with the atomic number 118.
The atomic number of an Element refers to it's position in The Periodic Table. The first element (Hydrogen - H) has the atomic number 1. The second element (Helium - He) has the atomic number 2. The fifty-second element (Tellurium - Te) has the atomic number 52. And so on.

An element's atomic number is the # of protons in its nucleus.
Silicon is a non meta element. Atomic number of it is 14.
