Chemistry Flashcards
A positively charged subatomic particle located in the nucleus of an atom
Proton
A subatomic particle with no charge located in the nucleus of an atom
Neutron
A subatomic particle with a negative charge that orbits the nucleus of an atom
Electron
A cluster of protons and neutrons at the center of an atom
Nucleus
An atom or group of atoms with an electric charge gained by losing or receiving an electron(s)
Ion
Variants of a particular chemical element, which differ in neutron number, but have the same number of protons
Isotope
All units of matter smaller than an atom
Subatomic Particle
The electron(s) in the outer shell of an atom that can aid in the creation of chemical bonds (main group elements)
Valence Electron
The group of electrons surrounding the nucleus in an atom
Electron cloud
The wave movement of an electron/ a way to gain an electron’s location
Orbital
The total number of protons and neutrons in the nucleus of an atom
Atomic mass
The total number of protons in the nucleus of an atom
Atomic Number
An extremely small unit of matter, composed of protons, neutrons, and electrons
