Chemistry Flashcards
1
Q
Ionic compounds
A
compounds containing positive and negative ions held together by the electrostatic force
2
Q
properties of ionic compounds
A
made up of positive and negative ions, usually solids at room temperature, high melting points due to strong electrostatic force, dissolvable in water, aqueous solutions normally conduct electrify
3
Q
what is ionic bonding
A
it is a type of bonding that involves the transfer of electrons from one atom to another.
4
Q
what is covalent bonding
A
bonds between non-metal elements. Formed by the sharing of electrons rather than the transfer and delocalisation and metallic bonding.
5
Q
what is an example of ionic bonding
A
sodium chloride
6
Q
what is an example of covalent bonding
A
water - H20
