what word describes the arrangement of ions in an ionic compound?
strong electrostatic forces
name the force between ionic bonds
ide
if a compound has 2 elements what will its name end in?
ate
if a compound has 3 or more elements what will its name end in?
high, hard to overcome the strong electrostatic forces
what is the boiling/melting point of an ionic compound? why is it this?
the ions are not free to move
do ionic compounds conduct electricity? why is this?
a metal and non-metal
what is an ionic bond formed between?
a non-metal and a non-metal
what is a covalent bond formed between?
a molecule
what is formed as a result of covalent bonds?
to become stable, have a full outer shell
why do atoms share electrons?
weak intermolecular forces?
what forces are between covalent bonds?
low, not a lot of energy is needed to overcome the weak intermolecular forces
what is the boiling/melting point of a simple covalent bond? why is this?
no, it has no free moving electrons
can a covalent bond conduct electricity? why is this?
one or more physical forms of an element that occurs in the same physical state
what is meant by the word allotrope?
4
