organic solvents

Most simple molecular compounds are soluble in ________ but not in water.

Graphite

A slippery allotrope of carbon.

Giant Molecular Structure

A substance containing a large number of atoms which are covalently bonded.

covalent bond

One ________ is represented by one line in the structural formula.

Covalent Bond

Chemical bonds formed by the sharing of electrons between atoms.

Metallic Bonds

A type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions.

Dutile

Able to be deformed without losing toughness..

Malleable

Able to be hammered or pressed into shape without breaking or cracking.

Allotropes

Each of two or more different physical forms in which an element can exist.

Diamond

Allotrope of carbon used for cutting due to its sharp edges.

Electrons

Stable subatomic particle with a negative charge.
