Most of our food is non-metal. Others would be plastics, fertilizers, combustion materials.
Nonmetals like flourine are used in dental offices to help stop and prevent tooth decay. Nonmetals like sulfur are mined and put into blackpowder rifles, as well as in fungicides, insecticides, and fumigants.
Non metals are used as insulators (poor conductors)
Yes, copper does form compounds with nonmetals.
Some of them do have an odor
Some are, some are not.
Nonmetals can be used as insulators in electrical wiring to prevent the flow of electricity. Additionally, nonmetals are used in the production of electronic components such as semiconductors and LEDs.
No, nonmetals are not invisible. Nonmetals such as oxygen, nitrogen, and carbon are visible in their gaseous form as they make up the air we breathe. Other nonmetals like sulfur and iodine can be seen in their solid or liquid forms.
We cannot determine if nonmetals are strong or not since they exist in any of the 3 states:solid,liquid,or gases. But generally,nonmetals are characterized that they are non-ductile. There are some nonmetals that are strong such as:wood and glass,and in the same time there are some nonmetals that are not as strong such as :coal which we can dismantle easily.

Most nonmetals do not have electrical conductivity because they lack the free electrons required to conduct electricity. However, some nonmetals like graphite and silicon can conduct electricity to some extent due to their unique structures.
Metalloids have some properties of both metals and nonmetals. They can exhibit characteristics of metals, such as conductivity, and characteristics of nonmetals, such as brittleness. Metalloids are found in a staircase pattern on the periodic table between metals and nonmetals.
Metalloids have properties of both metals and nonmetals. They can conduct electricity like metals but are brittle like nonmetals. Some examples of metalloids are silicon and germanium.
