amu
The unified atomic mass unit or dalton is the standard unit that is used for indicating mass on an atomic or molecular scale
neutron
The neutron is a subatomic particle, symbol n or n0, with no net electric charge and a mass slightly larger than that of a proton
metalloids
A metalloid is any chemical element which has properties in between those of metals and nonmetals, or that has a mixture of them
metal bond
Metallic bonding arises from the electrostatic attractive force between conduction electrons and positively charged metal ions
London dispersion force
London dispersion forces are a type of force acting between atoms and molecules
condensed structural formula
The structural formula of a chemical compound is a graphic representation of the molecular structure, showing how the atoms are arranged
polyatomic ions
A polyatomic ion, as a molecular ion, is a charged chemical species composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit
subatomic particles
In the physical sciences, subatomic particles are particles much smaller than atoms
halogens
The halogens or halogen elements are a group in the periodic table consisting of five chemically related elements: fluorine , chlorine , bromine , iodine , and astatine
