subtract the atomic number from the mass number
2 of 7
What is ionic bonding?
transfering electrons between a metal and a non-metal

explain a gaint ionic lattice
regular structure/ high melting point/ free ions conduct electricity/ disolve easily.

what is covalent bonding?
when electrons are shared between two or more non-metals
5 of 7
explain giant covalent srtuctures
very strong/ strong intermolecular bonds.
