The first ionisation energy depends on:the charge on the nucleus, the distance of the outer electron from the nucleus, the amount of shielding by inner electrons and whether the electron is alone in an or...

Firstly, expand the left hand side of the equation out to produce: [7x-35=25-3x]. Bring all the x's to one side (to form 10x=60). Divide both sides by 10 to find the solution for x [x=60/10]. Therefore, x...

a+a+4 = -p/5a+2 = -p/10(a+2)sqaured = q/5 +4p sqaured/100 = q/5 +4p sqaured = 100(q/5 +4)implies p squared = 20q+400

A good introduction provides clarity to the question and informs the reader to what is going to be argued.1.) An effective introduction immediately offers a clear judgement, this gives clarity to the main...
