Metals generally are good conductors of electricity, and nonmetals are not.

Insulators are typically nonmetals because they have high electrical resistance and do not conduct electricity well. Metals are good conductors of electricity, while metalloids have properties that are intermediate between metals and nonmetals.
nonmetals
Nonmetals such as sulfur, phosphorus, and iodine are unable to conduct electricity because they lack free-moving electrons in their atomic structure. This results in these nonmetals being poor conductors of electricity.
Metalloids have an intermediate ability to conduct heat and electricity, falling between metals and nonmetals. They have some metallic properties, such as being able to conduct electricity to some extent, but not as effectively as pure metals. Their ability to conduct heat and electricity can vary depending on the specific metalloid.
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.
The group of elements that do not conduct electricity are generally called non metals.
