Question

Which of the following is true about subatomic particles?

The mass of a neutron is the same as the mass of an electron.

Neutrons have a negative charge and are the heaviest subatomic particle.

Protons are positively charged and are one of the heaviest subatomic particles.

Electrons are neutral and are the lightest subatomic particle.

Answer 1

Answer:

I think the answer is C. protons are positively charged are one of the heaviest subatomic particles.

Explanation:

Electrons are negatively charged which is the basic unit of an electric charge

mass of the electron is 9.10938356 × 10−31 kg, which is only 1/1,836the mass of a proton.

Answer 2

Answer:

Protons are positively charged and are one of the heaviest subatomic particles

Explanation:

A typical atom consists of three subatomic particles: protons, neutrons, and electrons.

Using Method of elimination;

Option 1 - This is incorrect because the mass of a neutron is slightly greater than the mass of a proton. Electrons are extremely small. The mass of an electron is only about 1/2000 the mass of a proton or neutron

Option 2 - This is incorrect because Neutrons are neutral with no net charge however the mass of a neutron is slightly greater than the mass of a proton.

Option 3 - This is correct because protns are indeed positively charged as the name implies and are one of the heaviest sub atomic particles.

Option 4 - This is incorrect because electrons are negatively charged. However they are indeed the lightest sub atomic particle.
