I think the correct answer from the choices listed above is the second option. Oxygen and hydrogen are most likely to form covalent bonds. It <span>is a chemical </span>bond<span> that involves the sharing of electron pairs between atoms. Hope this answers the question. Have a nice day.</span>
Oxygen and Hydrogen would most likely form a covalent bond that is polar, or a polar covalent bond. Due to the electronegativity difference between the 2 elements, unequal sharing of the valence electrons will occur, electrons being in closer proximity to Oxygen and farther away from Hydrogen. Resulting in the characteristic partial positive and negative charges to appear for the respective elements.
You subtract the atomic number from the mass number to find the number of neutrons. If the atom is neutral, the number of electrons will be equal to the number of protons.
