Question

Write the symbol are element X, which has 22 electrons and 22 neutrons.

Answer 1

 the answer is titanium, look on periodic table :D

Answer 2

Answer: The isotopic representation of the element is $_{22}^{44}\textrm{Ti}$

Explanation:

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

Atomic number = number of protons = number of electrons

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

Mass number = Number of protons + Number of neutrons

The isotopic representation of an atom is: $_Z^A\textrm{X}$

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

We are given:

Number of electrons = 22 = Number of protons

Number of neutrons = 22

Mass number = 22 + 22 = 44

Hence, the isotopic representation of the element is $_{22}^{44}\textrm{Ti}$
