what describes a multiple covalent bond ?
four electrons are shared
share
covalent
ionic
transferred
As a bond between a hydrogen atom and a sulfur atom is formed, electrons are
shared to form a covalent bond
What type of bonding is present when valence electrons move within the sample ?
metallic
The bonds between the hydrogen and oxygen atoms in a water molecule are
polar covalent
what is an excellent conductor of electricity
metal - valence electrons are mobile
What occurs when potassium reacts with chlorine to form potassium chloride ?
electrons are transferred and the bonding is ionic
the malleability of gold is due to the
nature of the bonds between gold atoms
A solid sample of a compound and a liquid sample of the same compound are each tested for electrical conductivity. Which test indicates that the compound is ionic ?
the solid is a poor conductor, and the liquid is a good conductor
A sample of a substance with these characteristics:
- melting point of 984 K
- hard, brittle, solid at room temperature
- poor conductor as a solid
- good conductor as a liquid
This sample is classified as an
ionic sample

Which type of bonding is found in all molecular substances ?
covalent bonding
What is a property of a molecular substance
low melting point
the bonds in all network solids are
covalent
water molecules =
hydrogen bonding
molecular bond =
covalent
polar =
electronegativity difference between 0.4 and 2.0
non polar =
less than 0.4
