Q:

What is smaller than an atom?

A:

Atoms are made up of even smaller particles, such as protons and neutrons, which are formed from even smaller particles known as quarks. Subatomic particles form atoms, which in turn create molecules, the basic building blocks of matter.

Just as atoms can be combined to create different types of matter, subatomic particles are used to create different types of atoms. Protons and neutrons make up the nucleus of atoms, and it is the different combinations and configurations of these subatomic particles that are responsible for providing different types of atoms with various properties. Protons, neutrons and heavier particles, known as hadrons, are created from even smaller subatomic particles, known as quarks.

    What is the sum of protons and neutrons?

    A:

    The sum of protons and neutrons is the mass number. The mass of an atom is contained mainly within the nucleus where the protons and neutrons live. An electron's mass does not contribute significantly to the mass of the atom.

    What is an atom smasher?

    A:

    An atom smasher is a large installation commonly referred to as a particle accelerator. It works by accelerating electrons to a significant fraction of the speed of light and then crashing them into the nuclei of atoms. The resulting debris can then be searched for otherwise elusive particles that can shed light on theories of physics.
