They both resist the flow of electrons through the conductor..
The answer is D. more quickly when heat is added to them
Answer:
correct answer is D
Explanation:
In the covalent bond, a pair of electrons is shared between two atoms, in this case we have 4 electrons in one atoms and they are shared in pairs, so for these as far apart as possible due to electron-electron repulsion between the electrons of different bonds it must have a TETRAHEDRAL geometry
the correct answer is D
