Ascientist uses an accelerator and high energy electrons to study the particles inside the protons of a helium atom. what particles is the scientist studying?
a) the he neutrons
b) the he nucleus
c) the he electrons
d) the he quarks

D) the He quarks

Explanation:

Atoms are composed of fundamental subatomic particles; electrons, protons and neutrons wherein:

Atomic mass = protons + neutrons

Atomic number = number of protons = number of electrons

The protons and neutron present inside the nucleus of the atom are held by strong forces. A proton however can be further broken into quarks. Each proton is composed of 3 quarks: 2 up-quarks and 1 down-quark

Atomic number of He = 2. Therefore, it has 2 protons and a total of 6 quarks

ill try to . no promises tho.
