Which anion forms the smallest number of insoluble salts? 2 points (a) cl-

☆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

The net force is 100

Higher temperature = molecules move around faster. and vice versa.
