No, calcium is a metal and cannot be cut with a knife. It is a hard and brittle material that would require a specialized cutting tool, such as a hacksaw or grinder, to cut through.
Some metals, such as sodium and potassium, are soft enough to be cut with a knife. Nonmetals such as sulfur can also be cut with a knife due to their brittle nature. However, most metals and nonmetals are too hard to be cut with a knife.
Alkali metals can be cut with a knife because they are soft and have low melting points. Iron cannot be cut easily with a knife because it is a strong and hard metal. The differences in properties between alkali metals and iron make alkali metals easier to cut with a knife.
Calcium is a silver-white metal that is soft enough to be cut with a knife when it is freshly exposed. It has a dull luster when exposed to air due to oxidation.
No, pure magnesium metal is a hard and brittle material that cannot be easily cut with a knife. It is commonly used in alloy form for industrial applications.
