Answer:
the true statement is an atom contains the same number of electron and proton
Step-by-step explanation:
let us see the behaviour of the sub atomic particles
- nutrons and protons found in the nucleus of an atom
- an atom have the same number of electron and proton but they have different charge
- nutron is chargeless particle
- most mass of the atom concentrated in the nucleus of an atom
- electrons have almost 0 mass from an atom
- mass of proton and mass of nutron are equvalent or almost equal
there are many properties of subatomic particles i have listed some of them above .
