Atomic Structure And Properties Relating To Bonding

Front 1

Solids

Back 1

A substance having a definite shape and volume; one that is neither liquid nor gaseous.

Front 2

Liquids

Back 2

The state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility.

Front 3

Atom

Back 3

All elements are made of atoms. An atom consists of a nucleus containing protons and neutrons, surrounded by electrons.

Front 4

Atomic number

Back 4

The number of protons in the nucleus of an atom. Also called the proton number.

Front 5

electron

Back 5

Sub-atomic particle, with a negative charge and a negligible mass relative to protons and neutrons.

Front 6

electron arrangement

Back 6

The order electrons are arranged into between different energy levels.

Front 7

mass number

Back 7

The number of protons and neutrons found inside the nucleus of an atom.

Front 8

neutron

Back 8

Uncharged sub-atomic particle, with a mass of 1 relative to a proton.

Front 9

nucleus

Back 9

The central part of an atom. It contains protons and neutrons, and has most of the mass of the atom. The plural of nucleus is nuclei.

Front 10

proton

Back 10

Sub-atomic particle with a positive charge and a relative mass of 1.
