Answer 1

Answer:

sodium is the right answer

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:

• Sodium that has been sliced with a knife. 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 it. Because it has an empty area in the unit cell, potassium can be sliced with a knife.
• As a result of the weaker metallic connection, it can be sliced with a knife. When potassium is cut, it has a brilliant, sparkling surface that quickly fades to a bland colour.
