Explanation:
covalent bond poor thermal conductivity
molecular compounds
metallic bond ductile
electron sea model
ionic bond crystalline
hard and brittle
Covalent compounds have the following properties:
- Gases and volatile liquids or low melting point solids
- Often insoluble in polar solvents
- Mainly non - conductors
- Have slow reactions
Metallic compounds:
- Have good malleability, ductility, electrical and thermal conductivity.
- A large sea of electron by jointly packed atoms.
- They are mostly in metals
- Accounts for the bulk of the physical properties displayed by metals
Ionic compounds:
- High melting and boiling point
- Soluble in polar liquids
- Conducts electricity in molten or aqueous forms.
- Mostly crystalline solids
- Usually hard and brittle
- Undergoes fast chemical reactions

Answer:
Malleability is a capability of making shaped or extended by hammering.
For example:
making a a ring of gold by hammering and heating gold.
The state of matter with a specific volume but no definite shape is the <u>Liquid</u> state.
<u>Explanation:</u>
There are three states of matter according to chemical science: Solid, Liquid and Gas. There is not much space in among the molecules. The particles in a liquid are free to float, so while a liquid has a certain volume it has no definite form. Liquids are composed of atoms or molecules bound by inter molecular bonds.
Most of the liquids resist compression while some do not, unlike a gas, a liquid will not spread to fill any container room and will retain a fairly constant density. A characteristic liquid state property is surface tension that results to wetting phenomena. Water is perhaps the most frequent substance on Earth.
