Particle movement in a solid

Particles vibrate in fixed positions.

Three types of strong chemical bonds

Ionic, covalent, and metallic bonds.

Ionic bonding occurrence

Bonding that occurs between metals and non-metals.

Particles forming ionic bonds

Oppositely charged ions.

Outer shell electron transfer in ionic bonding

The transfer of outer shell electrons from metal atoms to non-metal atoms.

Group 6 non-metal ion charge

A charge of $-2$ formed when a Group 6 non-metal becomes an ion.

Electronic structure of a noble gas

A full outer shell configuration achieved by ions formed from Groups 1, 2, 6, and 7 to ensure stability.

Dot and cross diagram

A type of diagram used to represent the transfer of electrons in ionic bonding.

Giant ionic lattice

A regular, repeating structure of alternating positive and negative ions formed by ionic compounds.

Electrostatic forces in ionic compounds

Strong forces operating in all directions between oppositely charged ions that hold the lattice together.

Melting and boiling points of ionic compounds

High melting and boiling points, requiring a large amount of energy to break the many strong electrostatic forces between oppositely charged ions.

Conditions for ionic electrical conductivity

Occurs when an ionic compound is molten (melted) or dissolved in water (aqueous), as ions become free to move.

Covalent bonding

Bonding between non-metal atoms achieved by sharing pairs of electrons.

Oxygen molecule covalent structure

A small covalent molecule.

Double covalent bond

A covalent bond containing two shared pairs of electrons.

State of matter of small covalent molecules at room temperature

Usually gases or liquids.

Melting and boiling points of small covalent molecules

Low melting and boiling points.

Forces overcome when small covalent molecules melt or boil

Weak intermolecular forces.

Reason small molecules do not conduct electricity

Small molecules do not have an overall electric charge.

Effect of increasing molecule size on intermolecular forces

Intermolecular forces become stronger as the size of the molecule increases.

Effect of increasing molecule size on melting and boiling points

Melting and boiling points increase as the size of the molecule increases.

Polymer definition

A large molecule made of many repeating units linked together.

Bonds linking atoms in polymer molecules

Strong covalent bonds.

State of polymers at room temperature

Solids.

Strength of intermolecular forces between polymer molecules

Relatively strong intermolecular forces.
