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 smallest unit of matter?

    A:

    The smallest unit of matter is the atom. In the fifth century B.C., Democritus proposed that matter can only be cut up to a certain point. At that point, that smallest particle still retains the properties of that substance.

  • Q:

    What is an example of E=m*c^2?

    A:

    One example of E=m*c^2 is the equation that demonstrates the conversion of 1 kg of matter into 9.0*(10^16) J of energy. Examples of E=m*c^2, or the mass-energy equivalence equation, can be found in physics classrooms in equations that convert matter to energy and vice versa. The formula is based on the theory that matter is directly proportional to energy.

    Which halogen has the least negative electron affinity?

    A:

    The halogen with the least negative electron affinity is astatine, which has an electron affinity of -270 kilojoules per mole. The lower electron affinity is related to the larger atomic size of astatine. In larger atoms, electrons will not be as attracted to the nucleus.

    What did Einstein discover?

    A:

    Albert Einstein used mathematics and physics to prove properties of physics about which he and other scientists theorized. For instance, his work on Brownian motion, which involved vibrations caused when atoms collide with one another, proved that atoms and molecules actually exist.
