Atomic level
Atom
The basic building block of matter described as having three fundamental components electrons,
neutrons and protons
The number of protons in the nucleus of an atom which also indicates the number of
electrons in a stable atom
Atomic number
Atomic mass number
The number of protons and neutrons and atom has in its nucleus
Electron
negatively charged particle
,Electron
A subatomic particle with one unit of negative electrical charge and a mass significantly less
than that of protons or neutrons, orbiting the nucleus at high velocities
Fundamental particles
Protons, neutrons and electrons
Nucleus
The central part of an atom made up of protons and neutrons, and it is a core around which
electrons orbit
Proton
Has one unit of positive electrical charge and a mass of 1.673x10^-27kg
Proton
A component of the nucleus with one unit of positive electrical charge, and a specific mass
contributing to the atomic number of an atom
Neutron
no charge
Neutron
Component of the nucleus with no electrical charge and a specific mass contributing to the
majority of an atoms mass along with protons
Neutron
, Has no electrical charge and a mass of 1.675x10^-27kg
What composes the majority of the mass of an atom?
protons and neutrons
Electron
Has one unit of negative electrical charge and a mass of 9.109x10^-31kg
Electron
Has very little mass yet each one is moving extremely fast in its orbit, and thus it has a
significant kinetic energy
Alpha particles
Are made up of two protons and two neutrons and have a positive charge
No net charge
When an atom has an equal number of protons and electrons
Anion
A negatively charged ion
Cation
A positively charged ion
Binding energy
A measure of the amount of energy necessary to split an atom
