Question

1.write quark composition of proton and neutron.
2.a nucleus contains no electrons yet it eject them explin

Answer 1

Answer:

Protons are made of two Up and one Down quark. The neutron is made of two Down and one Up quark. The Up quarks have a 2/3 positive charge and the Down has a 1/3 negative charge.

Answer 2

The Quark is defined as a fundamental constituent of a matter and also defined as an elementary particle.

The quark has an electric charge,the charge of up quark is 2/3.

Quark composition : protons & neutrons.

proton:It contains two up quarks and one down quark.

neutron: it contains one up quark and two down quarks.

2))Nucleus contains no electrons

Nucleus does not contain free electron yet it emits beta particles.

During beta decay,the neutron in the nucleus convert into the proton with the ejection of electron and antineutrino.
