Will mark as brainliest. which statement correctly explains how magnesium and chlorine combine to form magnesium chloride? a) a cl atom donates two electrons to a mg atom b) an mg atom donates two electrons to a cl atom. c) a cl atom donates one electron to each of the two mg atoms. d) an mg atom donates one electron to each of the two cl atoms.

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
