The diagram below shows five of the
six types of quarks. Which type of quark is missing? (A) 𝛼, (B) 𝛽, (C) charm, (D) odd,
or (E) normal.
Quarks are defined as the subatomic
particles that make up protons and neutrons and are fundamental constituents of
matter. Murray Gell-Mann and George Zweig
independently proposed the quark model in 1964. The quark model states that many
large particles are made up of different types of quarks. Quarks can be considered to be
fundamental building blocks of matter because they make up larger particles such as
protons and neutrons.
There are six different types of
quarks. These are known as flavors of
quarks. The six flavors of quarks are up,
down, top, bottom, strange, and charm. You may have noticed that each of
them are represented by the lowercase form of the letter they start with. The quark that we were not given in
the question is charm. So the answer to the question
“Which type of quark is missing?” is (C) charm.
