Answer 1

An elements atomic number is the same as how many protons it has. So it has 86 protons

Answer 2

Answer:

This element have 86 numbers of protons.

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

It is denoted by Z.

Atomic number = Number of electrons = Number of protons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

It is denoted by A.

Mass number = Number of protons + Number of neutrons

We have, element whose atomic number is 86.

Atomic number = Number of protons = 86

This element have 86 numbers of protons.
