1.	Which metal can float in water?and why
Answer» Lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs) and francium (Fr). These metals float on water because of two reasons: they are very light weight metals and they react very aggressively with water to form hydrogen gas which helps them to float in water. Calcium can float in water because when calcium reacts with hydrogen and oxygen , bubble are formed that sticks to calcium and make it float.............✌️✌️✌️
