Question

What are 2 characteristics of noble gases? *

O Noble gases are not reactive with other elements.
O Noble gases have a single electron in the outermost shell.
O Noble gases are highly reactive and good conductors of electricity.
O Noble gases belong to group 18 of the periodic table.
O Noble gases all have two valence electrons.

Answer 1

Noble gases are unreactive and belong to group 18 of the periodic table.

Step-by-step explanation:

Two characteristics of noble gases are:

1. Noble gases are not reactive with other elements: Noble gases have full electron shells, which makes them stable and unreactive. They do not easily form chemical bonds with other elements.
2. Noble gases belong to group 18 of the periodic table: These elements are located in group 18 (VIII A) of the periodic table, also known as the noble gases or inert gases.
