Question

valence electrons are
select one:
o a. in various orbits around the nucleus
o b. not associated with a particular atom
o c. in the most distant orbit from the nucleus
o d. in the closest orbit to the nucleus

Explanation:

Valence electrons are the electrons in the outermost shell (the most distant orbit from the nucleus) of an atom. They are involved in chemical bonding. Option A is too general as it doesn't specify the outermost orbit. Option B is incorrect as valence electrons are associated with a particular atom. Option D refers to core electrons (in the closest orbit to the nucleus), not valence electrons.

Answer:

C. in the most distant orbit from the nucleus
