Answer:
elementary particles
Explanation:
Matter is composed of elementary particles i.e. quarks and leptons.
Matter is composed of elementary particles which is called quarks and leptons. Quarks consist of protons, neutrons and electrons. All observable matter is made up of up quarks, down quarks and electrons.
Lepton is an elementary particle consist of half-integer spin that does not undergo strong interactions. Leptons exist on two main classes i.e. charged leptons, and neutral leptons. Electron, electron neutrino, muon, muon neutrino, tau and tau neutrino are the six types of leptons.
Answer:
D. Allowing free electrons to escape from a negatively charged body
Explanation:
In order to neutralize a charge, an equal and opposite charge must be added or brought in contact with it.
From the options provided, only D is wrong.
Allowing free electrons to escape from a negatively charged body will cause the body to be positively charged. In such a body, the number of positively charged particles will be more. A neutralized atom or neutral atom has equal amount of positive and negative charges.
