Question

State two difference between the physical properties of potassium and vanadium

Answer 1

Physical properties

Potassium is a soft, silvery-white metal with a melting point of 63°C (145°F) and a boiling point of 770°C (1,420°F). Its density is 0.862 grams per cubic centimeter, less than that of water (1.00 grams per cubic centimeter). That means that potassium metal can float on water.

Physical properties

Vanadium is a silvery-white, ductile, metallic-looking solid. Ductile means capable of being drawn into thin wires. Its melting point is about 1,900°C (3,500°F) and its boiling point is about 3,000°C (5,400°F). Its density is 6.11 grams per cubic centimeter.
