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.
False
Not all nonmetals have an odor. Some nonmetals, like nitrogen and oxygen, are odorless gases at room temperature. However, certain nonmetals, such as sulfur and phosphorus, can have distinct odors. The presence or absence of an odor in nonmetals depends on their specific chemical properties and the forms they take.
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.
Most nonmetals are gases at room temperature, such as oxygen, nitrogen, and fluorine. Some nonmetals, like sulfur and carbon, are solids at room temperature.
False
No, all elements in the periodic table are made up of atoms that can be seen or detected using scientific instruments. Some nonmetals may have properties that make them difficult to see with the naked eye, but they are not invisible.
Yes, copper does form compounds with nonmetals.
Some of them do have an odor
Some are, some are not.

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.
