1.4 Bonding Flashcards
1
Q
ionic bonding
A
one atom donates one or more electrons to the other atom(s), resulting in a positive ion (cation) and negative ion (anion). Both ions have full outer shells of electrons.
2
Q
eg of ionic bonding sodium chloride
A
3
Q
eg of ionic bonding calcium bromide
A
4
Q
covalent bonds
A
the atoms share a pair of electrons to form a single covalent bond.
Each atom gives one electron to the bonding pair.
If two pairs of electrons are shared, a double bond is formed.
Each of the atoms in the molecule usually has a full outer shell of electrons.

Q
eg covalent
chlorine and oxygen
A
6
Q
coordinate bond
A
A coordinate bond is a covalent bond, but one of the atoms provides both electrons in the shared pair.

Q
eg coordinate bond
ammonia
A
