ionic bonds

HideShow resource information
how are ionic compounds held together?
by oppositely charged strong forces of attraction
1 of 9
which elements, other than those in group 1 and 7 form ions?
elements from group 2 and 6
2 of 9
how do elelmtns form compounds?
by reacting together by either gaining or losing electrons or by sharing
3 of 9
what charge will an atom get if it loses electrons
a posative chagre.
4 of 9
how can we write the formula of an ionic compound given its ion?
by looking at its ratio, using brackets and looking at them cancelling out
5 of 9
how are covalent bonds formed?
they are formed when atoms share pairs of electrons
6 of 9
what type of substances have covalent bonds?
simple molecules but have giant covalent structures.
7 of 9
how are the atoms in metals arranged
atoms closely packed together and arranged in regular layers.
8 of 9
how are the atoms in metals held together
held together with positively charged metal ions. there are delocalised electrons on the outermost shell. they can move throughout the lattice.
