Detailed Solution

The above statement is true.
Soft metal can be sliced without shattering and is simple to damage. It is not stiff and can withstand pressure and weight with little to no resistance. When touched, it feels fluffy and soft. Sodium is a chemical element with the atomic number 11 and the chemical symbol Na. It is a delicate, silvery-white metal that is exceedingly reactive. The forces between atoms of sodium are very weak. This atom is present in group 1 and has one electron in the valence shell. The metallic bonding in Sodium is not so strong, thus it can be cut down by using a knife. When oxygen in the air interacts with freshly cut sodium, it changes from bright to greyish-grey.
