Metals, Non-metals and Precipitates

Vocabulary flashcards based on lecture notes about the properties of metals and non-metals, atomic structure, and chemical bonding concepts.

Lustre

Shiny

Dull

Not shiny

Atom

The smallest particle that when reproduced many times will make up matter (Solid, Liquids and Gases)

Compound

A pure substance made up of two or more different elements chemically bonded together.

Molecules

Two or more atoms chemically bonded together. It could be an element or a compound.

Polyatomic Ion

A charged molecule composed of two or more atoms covalently bonded together.

Monatomic

An element that consists of single uncombined atoms.

Diatomic

An element that exists as two of the same atoms bonded together.

Atomic number

The number of protons in the nucleus of the atom.

Mass Number

The number of protons plus neutrons in the nucleus of an atom.

Ion

An atom that has lost of gained electrons

Ionic Bonding

The attraction of positive and negative ions for each other in a lattice.

Nucleus

contains positively charged protons and neutrons

Region of Space

Contains tiny positive electrons moving around very fast; often called an “electron cloud”

Element

A substance containing one type of atom that cannot be broken down into simpler substances by chemical means.

Ionic bonds

The chemical bonds that hold metal and non-metal ions together in an ionic compound
