What is the hardest mineral in this group
talc
What group? None given. Diamond is very hard. Talc is rather soft.
To determine the hardest mineral in a group, you can refer to the Mohs scale of mineral hardness. The Mohs scale ranks minerals based on their scratch resistance, with a scale ranging from 1 to 10. The higher the number, the harder the mineral.
To find the hardest mineral in a specific group, you need to identify the potential minerals within that group and compare their hardness ratings. Here are the known hardest minerals in certain groups:
1. Diamond: In the group of naturally occurring minerals, diamond has the highest ranking on the Mohs scale with a hardness of 10.
2. Corundum: In the group of oxide minerals, corundum (which includes rubies and sapphires) is considered the hardest mineral after diamond, with a Mohs hardness of 9.
3. Quartz: In the group of silicate minerals, quartz typically holds the top position for hardness, with a Mohs rating of 7. It is commonly used in various applications such as countertops and glass manufacturing.
Remember, the hardness ranking of a mineral is determined by its resistance to scratches from other minerals.
