Which element has 34 protons, 46 neutrons, 36 electrons?

The ion formed is

Explanation:

An ion is formed when an atom looses or gains electron.

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

Atomic number = number of protons = number of electrons

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

Atomic mass = Number of protons + Number of neutrons

The isotopic representation of an atom is:

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

We are given:

Number of protons = 34

Number of neutrons = 46

Atomic Mass = 34 + 46 = 80

Number of electrons = 36

As, the number of electrons is more than the number of protons, it forms negative ion

Hence, the ion formed is
