I think it’s A, because all of these are related to fossil fuel somehow.
Answer:
B) copper.
Explanation:
The reaction: Zn + Cu²⁺ → Zn²⁺ + Cu.
Zn losses 2 electrons and converts to Zn²⁺.
Cu²⁺ gains 2 electrons and converts to Cu.
So, the electron acceptor element is copper.
The right choice is: B) copper.
Answer:
The answer to your question is the third option, atoms of each lose one electron to achieve stability.
Explanation:
a) The first option is incorrect, those elements are extremely reactive and can explode.
b) The option is also incorrect, metalloids are located in groups 3A, 4A OR 5A in the periodic table.
c) This option is correct
d) These elements have 1 valence electron, this option is wrong.

Answer: Electrons in bonding orbitals stabilize the molecule because they are between the nuclei. They also have lower energies because they are closer to the nuclei. Antibonding orbitals place less electron density between the nuclei. The nuclear repulsions are greater, so the energy of the molecule increases.
