I've got a chem thing to do and I can;t seem to understand some of the stuff below. If you're capable. Help.

Does the formation of an ionic compound between the atoms of two elements involve the ionisation of the atoms of some elements? Or, does it involve he sharing of pairs of electrons between atoms?

The structure of solid calcium chloride is best described as:
a) dicrete molecules of calcium chloride with strong bonding within the molecule but weak bonding between molecules
b) an infinite lattice in which calcium and chloride are linked by strong covalent bonds

The property of metals which enables them to conduct an electric current is that:
a) metal atoms are better suited as charged carriers than non-metal atoms
b) ions in the metal are able to move freely through the metallic lattice.

Okay, you´re lucky

>>1.Does the formation of an ionic compound between the atoms of two elements involve the ionisation of the atoms of some elements? Or, does it involve he sharing of pairs of electrons between atoms?

The first one should be correct. Why, well, I can´t se what´s wrong with it and the second one has a small error in it. They do not have to be pairs of electrons. There are some ions that lack 3 electrones, instead of two (or one)


>>The structure of solid calcium chloride is best described as:

B is th only correct answer. Think of bone.

The property of metals which enables them to conduct an electric current is that:
a) metal atoms are better suited as charged carriers than non-metal atoms
b) ions in the metal are able to move freely through the metallic lattice.

A. Only electrons can move freely through solid metal. Not ions.

Good god, It´s been a while since I´ve had chemestry
