Question

Which metals are soft and can be cut with a knife?

Answer 1

• Metals are generally hard.
• But among the metals, Potassium and Sodium are soft.
• Since Potassium and Sodium are soft metals they can be easily cut with the help of a knife.
• All the other metals other than these two are hard and cannot be cut with the help of a knife.
• Therefore, Potassium (K) and Sodium (Na) metals are soft and can be cut with a knife.
