Ipt A particle contains 12 protons, 12 neutrons, and 10 electrons. What is the identity of the particle? O A. a neon atom
OB. a neon ion
O c. a magnesium atom
OD. a magnesium ion

D. a magnesium ion

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 12 protons than it must have 12 electrons.

In given question there are 12 protons and 10 electrons which means the neutral atom loses 2 of its valance electrons and form ion.

It is magnesium atom because mass of given atom is

Number of proton+ number of electron  = 12+12 = 24 amu

and atomic number is 12.

is there multiple choice answers?

i think so it’s will be b yes i believe its
