Proton - answer-a subatomic particle having a positvie charge identical in magnitude to the negative charge of an electron and, together with the neutron, a component of all atomic nuclei. The proton forms, by itslef, the nucleus of the hydrogen atom. The mass of a proton is approximately 1836 times that of an electron and the mass of an atom is contained almost entirely in the nucleus. The proton has an intrinsic angular momentum or spin and thus a magnetic moment (very small magnetic field). The number of protons in the nucleus of an atom determines what element it is; the atomic number of an element denotes the number of protons in the nucleus. Electron - answer-a subatomic mparticle that, along with protons and neutrons, make up the atoms the flow of an electric current in a conductor is caused by the drifting of free electrons in the conductor. Heat conduction is also primarily a phenomenon of electron activity. The charge of the electron is the basic unit of electricity. Electrons have half-integral spin; spin is a property of subatomic particles that indicates the particle's angular momentum. Neutron - answer-a subatomic particle that is neutral therefore has no charge. It is located in the nucleus and serves as a stabilizer. The mass of a neutron is slightly greater than the proton mass and has an enormous effect on the quantum spin value of an element. The net charge on a neutron is 0 Magnetism - answer-is descried as the ability of a substance to attract iron, cobalt and nickel. It is the power or force created by a substance having the property of creating or inducing magnetic dipoles. The magnetic field of any magnet has a direction, signified north and south. This property of a magnet makes it a dipole. Dipole - a magnetic field characterized by its own magnetic north and south poles separated by a finite distance. Magnetic susceptibility - answer-defined as the tendency of a substance to attract or repel magnetic lines of force dependent on the magnetic properties of its electrons.
