Question

An element X reacts with oxygen to form XO2 and with chlorine
to form XCl4. XO2 is a white solid that melts at high temperatures
(above 1000 °C). Under usual conditions, XCl4 is a
colorless liquid with a boiling point of 58 °C. (b) Do you think that
element X is a metal, nonmetal, or metalloid?

Accepted Answer

Hey everyone in this example, we need to determine whether our Adam X. Is a meta Lloyd, non metal or metal in the following molecules, X. O. And X. B. R. Two which have high melting points and are solids. What we should make note of is that in X. O our oxygen atom at room temperature exists as a gas. However, in our molecule X. B. R. Two, we would recognize that at room temperature bro, mean exists as a liquid. And according to the prompt, these molecules are both solids. So in order for these molecules to be solids we need to have a metal atom in our molecule and so we would say that therefore X must be a medal. So our molecules will be solid and this would be our final answer to complete this example. So X is going to be a medal. I hope that everything I explained was clear. If you have any questions, please leave them down below and I will see everyone in the next practice video.
