What types of elements- metals, nonmetals, or metalloids require
the most energy to remove an
electron?
Why do these elements have a higher ionization energy?

Noble gases

Explanation:

The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.

The reason for this difficult is that their electronic configuration confers a stable configuration them.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
