Answer:B. A molecule. I hope this helps you
Step-by-step explanation:
The correct answer is B - a molecule. When atoms join together with a covalent bond, they are sharing electrons with each other to form a stable molecular structure. This can happen between two or more non-metal atoms, and the resulting compound will have a neutral charge. Unlike an ion, which has a charge due to a gain or loss of electrons, a molecule is stable and does not possess an overall charge. Additionally, the bond formed between two atoms is strong and requires energy to break. This is different from a noble gas, which refers to an element that has a full outer shell and therefore does not easily form bonds with other elements.
