Question

which sun-atomic particle have opposite charge of a proton?
(a).electron
(b)neutron
(c) both a and b
(d)none of these​

Answer 1

Answer:

$\fbox \blue{Answer}$ $\fbox \red{Electrons}$

Electrons are extremely small. The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1.

Answer 2

Answer:

a) Electron

Explanation:

Given that these particles make up atoms, they are often referred to as subatomic particles. There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.
