bonding Flashcards
types of bonds
1
Q
what is an ionic bond?
A
a bond between a negative and positive ion held together by strong electrostatic attractions. eg. NaCl
2
Q
why do ionic compounds have high melting points?
A
the electrostatic attraction between the oppositely charged ions are strong, therefore requiring a large amount of energy to break the bond
3
Q
what is a covalent bond?
A
the electrostatic attraction between the positive nuclei of the bonded atoms and the shared electrons between them eg. CH4
4
Q
what is a coordinate bond?
A
a bond where both of the shared electrons are provided by one atom eg. NH4+
