Which of the following are the properties of a proton? 1. Proton is a positively charged particle. 2. Protons are found outside the nucleus of an atom. 3. The charge of a proton is equal and opposite to the charge of an electron. Correct Answer 1 and 3 only

The correct answer is 1 and 3 only.

CONCEPT:

  • Atoms contain subatomic particles called electrons, protons and neutrons.
  • Electrons: They are negatively charged particles.
  • Mass of an electron is about the mass of a hydrogen atom, which is about 9.1X10-31 kg.
  • They are located outside the nucleus of an atom.
  • Neutrons: It is a neutral particle found inside the nucleus of an atom.
  • The mass of neutron is equal to the mass of a proton, which is about 1.6 X 10-27 kg.

EXPLANATION:

  • Proton is a subatomic particle present in an atom.
  • It is a positively charged particle found inside the nucleus of an atom.
  • The charge of a proton is equal and opposite to the charge of an electron, which is equal to 1.602X10-19coloumb.
