ionic bonding

Question 1

what are ions

Answer 1

ions are charged particles which are formed when atoms gain or lose electrons

Question 2

ionic bonding is a bond formed by a ___ and a ___

Answer 2

metal and nonmetal

Question 3

when atoms become ions they have a ____ ____ electronic configuration

Answer 3

noble gas

Question 4

describe in terms of electrons what happens when a metal combines with a non-metal for an ionic bond (eg Na and O)[3]

Answer 4

mention:
transfer of electrons
direction of transfer (metal to non-metal)
number of each ion needed / number of electrons gained

Question 5

what is ionic bonding?

Answer 5

SEFABOCI

Question 6

what is an ionic crystal?

Answer 6

A giant 3D lattice structure held together by the attraction between oppositely charged ions
There are no individual molecules in an ionic bond

Question 7

do ionic compounds conduct electricity while solid? Why?

Answer 7

No. The ions cannot move due to the electrostatic force which binds the ions together.

Question 8

do ionic compounds conduct electricity when molten or in aqueous solution?

Answer 8

Yes, because the ions can move in molten or aqueous solutions.
