Question

cecil is working with samples of chlorine (cl), oxygen (o), bromine (br), and silver (ag). the samples are all at room temperature. which substance is most likely the most dense?
chlorine
oxygen
bromine
silver

Explanation:

To determine the most dense substance, we consider the states of matter at room temperature: chlorine (Cl) and oxygen (O) are gases, bromine (Br) is a liquid, and silver (Ag) is a solid. Solids generally have higher density than liquids and gases because their particles are closely packed. Among these, silver is a metal (solid), while the others are non - metals in gaseous or liquid states. So silver is most likely the most dense.

Answer:

D. silver
