Question

Helium (He), neon (Ne) and argon (Ar) are all colorless, odorless gases with low chemical reactivity. Based on the periodic table, which of the following is correct?

A.
Chlorine (Cl) is a colorless, odorless gas with low chemical reactivity.
B.
Carbon (C) is a colorless, odorless gas with low chemical reactivity.
C.
Selenium (Se) is a colorless, odorless gas with low chemical reactivity.
D.
Xenon (Xe) is a colorless, odorless gas with low chemical reactivity.

Answer 1

The answer would be D., Xenon.

Answer 2

D.Xenon (Xe) is a colorless, odorless gas with low chemical reactivity.

Step-by-step explanation:

As you know in the periodic table you can find elements that are similar in properties and characteristics in the same column so if you find Helium, Neon, and Argon in a column and have certain properties, all the elements that are found in that same column would have similar properties, from the options the only element that can be found in the same column as He, Ne, and Ar, is Xenon, which are all noble gases.
