A 122 g metal bar requires 2.50 kJ to change its temperature from 27.5 oC to 100.0 oC. What is the specific heat of the metal?

Sorry i think the answer is b

☆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
