Subatomic Particles & its discovery MCQ Quiz - Objective Question with Answer for Subatomic Particles & its discovery - Download Free PDF

Thee correct answer is Neutron.​Key Points

• James Chadwick achieved a breakthrough in nuclear research in 1932 when he confirmed the existence of neutrons, which are elementary particles that have no electrical charge.
• The neutron is a subatomic particle with the symbol n or n⁰ and a mass slightly more than that of a proton. It has a neutral charge (no positive or negative charge).

Important Points

• A proton is a stable subatomic particle with a positive electric charge of +1e elementary charge and the sign p, H⁺, or ¹H⁺.
• A neuron, also known as a nerve cell, is an electrically excitable cell that communicates with other cells through synapses, which are specialised connections between cells.
• Electron, lightest stable subatomic particle known. It carries a negative charge of 1.6 × 10⁻¹⁹ coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1 × 10⁻³¹ kg, which is only 1/1836 of the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.

The correct answer is 100 GeV.

Key PointsUnderstanding the Higgs Boson's Mass

• The Higgs boson is a fundamental particle associated with the Higgs field, which is responsible for giving mass to other particles.
• The discovery of the Higgs boson at the Large Hadron Collider (LHC) by the ATLAS and CMS experiments in 2012 confirmed the existence of the Higgs field.
• The rest mass of the Higgs boson is estimated to be around 125 GeV (Giga electron Volts), which is equivalent to approximately 100 GeV when considering the range within which this value is expected to fall.
• This mass is significantly higher than that of other subatomic particles, highlighting the unique nature of the Higgs boson.

Additional Information

• The Higgs field is an energy field that is thought to exist throughout the universe. The interaction of particles with this field is what gives them mass.
• The concept of the Higgs field and Higgs boson is a central part of the Standard Model of particle physics, which is a theory that describes the fundamental particles and forces that govern the universe.
• The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider, located at CERN (European Organization for Nuclear Research). It was instrumental in the discovery of the Higgs boson.
• The discovery of the Higgs boson was a monumental achievement in physics and earned the 2013 Nobel Prize in Physics for François Englert and Peter Higgs, who had theorized the existence of the Higgs boson in the 1960s.

The correct answer is 1932.

Key Points

• Carl Anderson:-
  • He was an American physicist who won the Nobel Prize in Physics in 1936 for his discovery of the positron.
  • Anderson's discovery also led to the development of positron emission tomography (PET), which is now widely used in medical imaging.

Additional Information

• Positron:-
  • It is the antiparticle of an electron and has the same mass as that of an electron but carries a positive charge.
  • The discovery of the positron provided evidence for the existence of antimatter, which was predicted by Paul Dirac in 1928.
