Atom by Mind Map: Atom

1. electron

1.1. Electrons are one of three main types of particles that make up the atom. They are extremely small and have an electric charge of −1. All atoms have the same number of electrons as protons.

1.1.1. On the other hand, when an atom gains an electron, it contains more electrons than protons and therefore has a negative charge. ... Atoms that have different number of protons but the same number of electrons are referred to as isoelectronic atoms.

2. orbital

2.1. Orbital, in chemistry and physics, a mathematical expression, called a wave function, that describes properties characteristic of no more than two electrons in the vicinity of an atomic nucleus or of a system of nuclei as in a molecule.

3. nucleus

3.1. neutron

3.1.1. The neutron is a neutral subatomic particle found in the atomic nucleus. The neutron is a subatomic particle with a mass of 1 and charge of 0. Neutrons are found with protons in the atomic nucleus. While the number of protons in a atom determines its element, the number of neutrons determines its isotope. d

3.2. proton

3.2.1. A proton is a subatomic particle with a positive charge. The atomic number is the number of protons in the nucleus of an atom. Isotopes are atoms of an element with the normal number of protons and electrons , but different numbers of neutrons.

3.3. proton plus neutron

3.3.1. a nucleon is either a proton or a neutron, considered in its role as a component of an atomic nucleus.
