Detailed explanation-1: -The correct answer is All minerals are non-metallic. A naturally occuring substance that has a definite chemical composition is called Mineral.
Detailed explanation-2: -A mineral is a naturally occurring inorganic substance which has a definite chemical composition, and which commonly, but not always, is crystalline. Most minerals are solid, but some ‘minerals’ such as native mercury are normally liquid in their natural state, and others, such as natural gas, are gaseous.
Detailed explanation-3: -Solid: Liquids and gases are not considered minerals, in large part because their structure is constantly changing, which means they do not have a characteristic crystal structure. A true mineral must be solid.
Detailed explanation-4: -Liquids and gases do not have an ordered crystal structure and are not minerals.
Detailed explanation-5: -Wood-is not considered a mineral because its an organic material.
