Going down the 1st column of the periodic table the group 1 metal have increasing numbers of electrons.All group 1 metals have a single electron in their outer shell and with an increasing number of elect...

(The answer really depends on the level of the student, hence more or less explanation might be needed.)The VSEPR (Valence Shell Electron Pair Repulsion) theory is used within chemistry to predict the geo...

Aldehydes can be differentiated from ketones as they give a positive result for the following tests -Tollens' reagent turns from a colourless solution to a silver precipitate.Fehling's solution turns from...

Metal complexes are kept together by a 'sea' of free electrons holding the negatively charged metal ions togetherCOMPARED TOIonic - positive ions and negative ions held together in a complex by electrosta...

An atom of nitrogen has 5 valence electrons in its outer shell. Each hydrogen atom in ammonia bonds to the central nitrogen atom and contributes an electron each. This means there are 8 electrons in total...
