Why do metals conduct electricity so well?
have a shared "sea of electrons" to carry the current.
electrons are stuck in place so they can pass the current
metals do not conduct electricity
they transfer electrons from one atom to another

Which of these elements is a metalloid?
Antimony (Sb)
Aluminum (Al)
Bismuith (Bi)
Oxygen (O)
Why do nonmetals tend to gain electrons?
They have fewer electrons in their outermost energy level and gaining electrons allows them to achieve a stable electron configuration.
They have the same number of electrons in their outermost energy level as metals, so they need to gain electrons to become stable.
Nonmetals do not tend to gain electrons, they actually lose electrons to achieve stability.
They have more electrons in their outermost energy level and gaining electrons allows them to achieve a stable electron configuration.
How do metalloids behave in terms of conductivity?
Highly conductive
Semiconductors
Insulators
Superconductors
