Question

for electrons to easily flow, they need:
a) a path with five or more electrons in the outer orbit
b) a path with three or fewer electrons in the outer orbit
c) a path with three or fewer protons in the nucleus
d) a path with five or more protons in the nucleus

Explanation:

Materials with atoms having three or fewer electrons in the outer - orbit are good conductors. Electrons can flow easily in such materials as the outer - shell electrons are loosely bound and can move freely.

Answer:

B) A path with three or fewer electrons in the outer orbit
