Give an example of one type of energy transformation (change to another form). be sure to explain your example.

Chemical energy in a match when activated lighting it releases thermal energy

hope that helps 

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts
