|
How are ions formed?
|
By the loss or gain of electrons.
|
|
|
Describe the formation of ionic bonds.
|
They form between metals and non-metals, exemplified by elements from Groups I and VII.
|
|
|
Are electrons shared or transfered in ionic bonds?
|
Electrons are transfered, resulting in full outer shells.
|
|
|
Describe the lattice structure of ionic compounds.
|
A regular arrangement of alternating positive and negative ions.
|
|
|
What happens when two non-metal atoms react together?
|
They share electrons because they both need tro gain electrons to reach full outer shells.
|
|
|
What type of elements react to from covalant compounds?
|
Non-metallic elements.
|
|
|
Describe the differences in volatility between ionic and covalent compounds.
|
Covalent compounds have low melting and boiling points, unlike ionic bounds, which have high boiling and melting points. Thus covalent compounds are more volatile.
|
|
|
Describe the differences in solubility between ionic and covalent compounds.
|
Ionic compounds are usually soluble in water, unlike covalent compounds, which are less soluble.
|
|
|
Describe the differences in electrical conductivity between ionic and covalent compounds.
|
Ionic compounds can conduct electricity when melted or dissovled, and the lattice breaks up and ions are free to move. Covalent compounds are not charged, thus they do not conduct electricity.
