Answer 1

Answer:

•The hardest substance occuring in nature is diamond

•The softest substance occuring in nature is soapstone or talc.

Answer 2

Diamond is the hardest and Talc is the softest substance occuring in nature

Explanation:

• Diamond is hardest: Extraordinarily strong chemical bonds, resulting in a tetrahedral crystal that is exceedingly hard.Because diamonds are comprised of carbon, they develop as carbon atoms at high temperatures and pressures, bonding together to form crystals. Each carbon atom participates in four of these incredibly strong covalent bonds that form between carbon atoms, which is why a diamond is such a hard substance.
• Talc is softest: Talc, commonly known as soapstone, is the softest mineral on the Mohs scale; it is made up of a stack of weakly linked sheets that tend to separate under pressure. In the case of metals, scientists attempt to quantify hardness in absolute terms.
