As compared to electron, proton is about __________ times heavier.

The correct answer is Option 3.

Key Points

• A proton is approximately 1836 times heavier than an electron.
• The mass of a proton is about 1.6726 x 10^-27 kilograms.
• In contrast, the mass of an electron is about 9.1094 x 10^-31 kilograms.
• This significant difference in mass is due to the fact that protons are made up of three quarks held together by the strong nuclear force, while electrons are elementary particles.

Additional Information

• Proton:
  • Protons are positively charged subatomic particles found in the nucleus of an atom.
  • They were discovered by Ernest Rutherford in 1917.
  • Protons determine the atomic number of an element, which defines its position in the periodic table.
• Electron:
  • Electrons are negatively charged subatomic particles that orbit the nucleus of an atom.
  • They were discovered by J.J. Thomson in 1897.
  • Electrons play a crucial role in chemical bonding and electricity.
• Quark:
  • Quarks are elementary particles and fundamental constituents of matter.
  • Protons and neutrons are made up of three quarks each.
  • There are six types of quarks: up, down, charm, strange, top, and bottom.
• Strong Nuclear Force:
  • The strong nuclear force is one of the four fundamental forces of nature.
  • It is the force that holds protons and neutrons together in the nucleus.
  • This force is incredibly strong but acts over very short distances.
