An atom has a mass number of 22 and an atomic number of 12. How many neutrons<br> does it have?
tia_tia [17]

Answer:

this isn't correct answer but the equation is correct by using this methid you can got your answer .

Explanation:

Given - Mass number of atom = 23

                                Atomic number of atom = 11

As, no. of electrons in an atom is equal to an atomic number of the element.

So, number of electrons = 11

Secondly , number of protons are equal to number of electrons.

so, number of protons = 11

And number of neutrons = mass number - atomic number = 23−11 = 12

so, number of neutrons = 12

So , the atom contains 11 protons, 11 electrons, 12 neutrons.
