An atomic number is the number of protons in an atom. In Selenium there are 34 electrons and protons in its structure and are represented by Se.

What are subatomic particles?

Subatomic particles are the particles that make up the atom and are the fundamental unit of matter. Electrons, protons, and neutrons are the subatomic particles that make up the atom.

The atomic number is the number of protons and hence it will be 34. In an atom, the number of electrons and protons are the same and hence it will be also 34. The atomic mass of the element is 78.09 and the number of neutrons is 44.

Therefore, the symbol of the Selenium atom is [tex]\rm ^{78}_{34}Se.[/tex]
