Short Answer

Expert verified
d. Building blocks of larger particles.

Step by step solution

01

Understanding Quarks

Quarks are fundamental particles that combine to form larger particles called hadrons, including protons and neutrons.
02

Analyze Options

Examine each of the given options to determine which one accurately describes quarks.
03

Eliminate Incorrect Options

a) Virtual particles - Quarks are not virtual particles.b) Massless particles - Quarks have mass.c) Candidates for dark matter - Quarks are not considered candidates for dark matter.
04

Identify the Correct Option

d) Building blocks of larger particles - This correctly describes quarks, as they are the building blocks of hadrons such as protons and neutrons.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Fundamental Particles
Quarks belong to a group known as fundamental particles. These are particles that cannot be broken down into smaller components.
Fundamental particles are essential elements of the universe. They are the building blocks of everything.
Other examples include leptons, such as electrons.
Hadrons
Hadrons are larger particles made from quarks. This group includes protons and neutrons.
Hadrons are part of the baryon family. Baryons consist of three quarks.
The two most well-known hadrons are the proton and the neutron, essential components of an atom's nucleus.
Protons
Protons are a type of hadron. They are made up of two 'up' quarks and one 'down' quark.
Protons carry a positive electric charge.
They are found in the nucleus of an atom, playing a crucial role in defining the element.
Neutrons
Neutrons are also a type of hadron. They are made up of one 'up' quark and two 'down' quarks.
Neutrons have no electric charge, making them neutral.
They, along with protons, form the nucleus of an atom, contributing to its mass.
