structure and bonding

?
What is a compound?
A compound is a substance which is formed of 2 or more chemical elements that are chemically bonded together.
1 of 9
Which type of bonding involves sharing electrons?
A covalent bond forms when two non-metal atoms share a pair of electrons.
2 of 9
Which type of bonding involves transferring electrons?
Ionic bonding is the complete transfer of electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmet
3 of 9
When are atoms at there most stable?
When their outer shell is completely full of electrons.

What happens to an atom when it becomes a positive ion?
An atom that gains or loses and electron is called an ion. Electrons are of negative charge so when and atom is lost, the atom becomes positively charged.
5 of 9
What happens to an atom when it becomes a negative ion?
An atom that gains or loses and electron is called an ion. Electrons are of negative charge so when and atom is gained, the atom becomes negatively charged.
6 of 9
Ions have the structure of noble gases in group 0, what does this mean?
That both noble gas and ions have full outer shells.
7 of 9
What charge do group 1 ions have?
a +1 charge.
8 of 9
What charge do group 1 ions have?
a +1 charge. For example: Na has a charge of +1 so its ion symbol is Na+
