Question

Helium is a colorless gas that does not react with other elements. Using what you know about valence electrons, which other elements would you expect to have similar properties as Helium? Explain.

Answer 1

Neon, Argon, Krypton, Xenon and Radon

Step-by-step explanation:

The other elements that would be expected to have similar properties as the Helium from the periodic table are the noble gases.

The noble gases are a special group of elements belonging to the last group of the periodic table.

They are called the O group or inert group because elements in this group do not combine with other atoms due to their completely filled outermost shell.

This makes them unreactive and do not readily combine with other atoms.
