Which of these elements is unlikely to form covalent bonds? So we have here sulfur, we have hydrogen, we have potassium, we have argon, and we have silicon. So remember covalent bonds are the sharing of electrons between non metals between nonmetals.
If we take a look here sulfur is a nonmetal so sulfur could form covalent bonds. Hydrogen is a nonmetal. Potassium is a metal. We said that it's between nonmetal, so this can't ever form covalent bonds. Let's look at the other options. We have argon and then we have silicon.
Argon is a nonmetal. Silicon is a metalloid. Now, technically, remember, metalloids share characteristics of both metals and nonmetals, and we'll see that because it's a metalloid and shares some nonmetal characteristics. There is the potential to form covalent bonds, right? So Eve has the potential.
C can't ever have the potential informing covalent bonds because it's strictly a metal. So just remember when it comes to covalent bonding, it's the sharing of electrons between elements that have non metallic characteristics.
