Question

the periodic table is shown below. helium (he), neon (ne) and argon (ar) are all colorless, odorless gases with low chemical reactivity. based on the periodic table, which other element would also have those same properties? a. selenium (se) b. chlorine (cl) c. xenon (xe) d. carbon (c)

Explanation:

Helium (He), neon (Ne), and argon (Ar) are noble gases (group 18 elements) with properties like being colorless, odorless gases with low chemical reactivity. Xenon (Xe) is also a noble gas (group 18), so it shares these properties. Selenium (Se) is a non - metal but not a noble gas, chlorine (Cl) is a halogen (group 17) with high reactivity, and carbon (C) is a non - metal with different properties.

Answer:

C. xenon (Xe)
