Answer 2

A soft metal can be defined as one that is simple to damage and cut without shattering. It is not difficult to work with and provides little to no resistance to pressure and weight. When you touch it, it feels soft and fluffy.

Explanation:

• Metals that can be sliced with a knife are sodium and potassium.
• The reason for this is that sodium only has one electron in its outer orbital, known as the one valence electron. It has a large size because it is the first element of period 3.
• This indicates that the attraction between particles that attaches metallic ions to electrons is weak. This indicates that sodium's metallic bonding is weaker than that of other metals. When sodium is freshly cut, it looks bright, but when it reacts with oxygen in the air, it turns a drab grey colour.
• As a result, a knife can be used to cut Sodium.
