Question

Atomic number of bismuth is:

Answer 1

Every atom consists of a nucleus in which protons that are positive in charge and neutrons which are neutral in nature i.e. carry no charge are present and electrons which are negatively charged are revolving around the nucleus.

Complete step-by-step answer: Number of protons and number of electrons in an atom is always equal as they neutralize the whole charge on the atom. Atomic number is also known by the name proton number and represented by the symbol Z. It basically tells us about the number of protons present in an atom. Atomic numbers are unique for every chemical element.
Atomic number is identical with charge number of nucleus and in case of an uncharged atom, the atomic number will be equal to the number of electrons revolving around the nucleus. Sum of atomic number and number of neutrons gives the mass number of an atom.
Bismuth is a chemical element represented by the symbol Bi present in the 6th period of periodic table and it is a p-block element. It is a pentavalent post transition element whose chemical properties resemble arsenic and antimony. Atomic number of bismuth is 83 i.e. the number of protons present in bismuth is 83. It is brittle metal having silvery white color.

Note: There are many applications of bismuth like it is used in cosmetics, pigments and have many applications in pharmaceutical industries like bismuth is used in the treatment of diarrhea and has low toxicity for heavy metals.
