The name for the Cu(CN)2*9H2O is

During photosynthesis, plants transform electromagnet energy from the sun into chemical energy.

Mgo2 is the oxidation state of manganese oxide

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

☆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
