Using the periodic table, explain which pair of the following gases have the most similar properties and why. Nitrogen (N), Fluorine (F), Neon (Ne), Krypton (Kr), and Oxygen (O).

 Neon (Ne) and Krypton (Kr)Explanation:

Elements that belong to the same group of the periodic table (column) have similar properties. This is because elements of the same group have the same amount of valence electrons. This means that chemically and especially in a chemical reaction (or lack thereof), they will behave similarly.

Neon and Krypton are the only two gases in the list given that belong to the same group of the periodic table (Group 18 - Noble Gases) and as such have similar properties.

Similar Properties of Neon and Krypton:

- Both have 8 valence electrons - They both are very stable and almost unreactive- Both are gases at RTP-Both are odorless, colorless, and tasteless until interaction with an electrical charge.

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).

Your answer is a just took the test
