Question

Give two difference in the chemical property of potassium and vanadium

Answer 1

Explanation:

(1) 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.

(2)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.
