Hi everyone please note that stuvia displays this powerpoint doc format funny and it doesn't actually look so zoomed in when you download. Its a summary and study guide exam pack for grade 8 students learning the following topics: The Berlin Conference The Causes of colonization of Africa The patterns of European colonization Administration of the colonies European advantages (Technology and military) Weaknesses in Africa Results/impact of colonization (Economic, social and political ...

first ionisation energy - ANS-The energy required to remove 1 mole of electrons from 1 mole of gasous molecules to form 1 mole of gasous ions.

This question is about atomic structure.There is a general trend for an increase in ionisation energy across Period 3. Give one example of an element that deviates from this trend. Explain why this deviation occurs. : Aluminium / Al(Outer) electron in (3)p orbital / sub-shell (level) (3p) higher in energy / slightly more shielded (than 3s) / slightly further away (than 3s) Give an equation, including state symbols, to represent the process that occurs when the third ionisation energy of...
