Electrons are being shared between atoms in a certain compound. Which elements could most likely form this compound?

lithium (Li) and fluorine (F)

aluminum (Al) and iodine (I)

sulfur (S) and oxygen (O)

iron (Fe) and chlorine (Cl)

Answer 1

S & O

Step-by-step explanation:

Electrons can be shared when both atoms are non-metal.

(called Covalent Compound)

Answer 2

sulfur (S) and oxygen (O)

Step-by-step explanation:

Compounds are made of molecules. Molecules are formed when two similar or different atoms are bonded together. These bonds are formed either by transfer or by sharing of electrons.

Chemical bonds that are formed by transfer of electrons are called ionic bonds. Bonds that are formed by sharing electrons are called covalent bonds.

1. Ionic bonding occurs between metals and non-metals, where a metal gives away its electron/s and non-metal accepts it.
2. Covalent bonding occurs between non-metals. It could be between atoms of the same element or atoms of different elements. For example

• Cl - Cl (covalent bond between atoms of same element)
• N-O (covalent bond between atoms of different elements)

Now option A, B and D have a metal in each (Lithium, Aluminum, Iron). So, they will form ionic bond with their respective non-metal. Option C has both non-metals. Hence, they will share electrons and form covalent bond between themselves.

Therefore, the correct answer is C
