Question

Compare the properties of electrons, protons, and neutrons.

Answer 1

Answer:

Electrons are a type of subatomic particle with a negative charge. ...Protons and neutrons have approximately the same mass, but they are both much more massive thanelectrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.

￫ Proton :

1. They are positively charged.
2. They are present in the nucleus of all atoms.
3. The mass of the proton is taken as one unit and equals the mass of a neutron.
4. A proton is represented as “p”.

￫ Neutron :

1. They are neutral.
2. They are present in the nucleus of all atoms except hydrogen.
3. The mass of the neutron is considered as one unit and it equals the mass of a proton.
4. A neutron is represented as “n”.

￫ Electron :

1. They are negatively charged.
2. They are present in the outer shells within an atom and orbit the positively charged nucleus in well-defined orbits.
3. The mass of an electron is about 1/2000 times the mass of a hydrogen atom.
4. An electron is represented as “e”.
