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.Learn More
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.Full Answer >
The neutron is a subatomic particle found in the nucleus of the atom and has no charge. The number of neutrons in the nucleus is different for different elements. In some cases, the number of neutrons can vary within atoms of the same element.Full Answer >
A beta particle is an electron emitted from the nucleus of an atom that has undergone beta decay. The electron is called a beta particle as a way of distinguishing it from the electrons present in the atom's shell.Full Answer >
An alpha particle is made up of two protons and two neutrons. An alpha particle is common in the field of nuclear physics because it is one of the three particles emitted during radioactive decay. The three particles emitted during radioactive decay are alpha, beta and gamma.Full Answer >
