METAL STRUCTURE

All metals have similar properties BUT, there can be wide variations in melting point, boiling point, density, electrical conductivity and physical streng...

Electron pairs arrange themselves so they are as far apart as possible (electron pair repulsion theory). In a covalent compound, the number of electron pairs around the central atom determines the shap...

The Gibbs free energy of a process is a measure of how readily that process will proceed on its own - a negative value means that the reaction is spontaneous, a positive value means that it is not, and...

This is the sort of question you are likely to stumble across in an IB HL Paper 2 examination. It would probably carry a few more marks and thus require a longer answer, but that is reason to panic!First ...
