Question

In the diatomic molecule HCl, the H and the Cl share a pair of

electrons. By doing so, the hydrogen atom attains the electron
configuration of while chlorine attains the electron
configuration of

Answer 1

helium and argon

Step-by-step explanation:

• The helium dimer is a van der Waals molecule containing two helium atoms with the formula He2. This chemical is the biggest diatomic molecule, which is a molecule made up of two atoms that are bound together. This dimer's connection is so weak that it will break if the molecule spins or vibrates too much.
• The noble gases (helium, neon, argon, krypton, xenon, and radon) are also monatomic gases at STP. To distinguish them from other gases that are chemical compounds, homonuclear diatomic gases and noble gases are referred to as "elemental gases" or "molecular gases."
