Which Nobel gas electron structures do the atoms in a molecule of hydrogen chloride attain?
And can you tell me why aswell please?

The noble as structures attained are helium and argon

Explanation:

The electron configuration of chlorine atom is 1s²2s²2p⁶3s²3p⁵

The elecron configuation of hydrogen is 1s¹

The electron configuration of argon atom is 1s²2s²2p⁶3s²3p⁶

The elecron configuation of helium gas is 1s²

Therefore, in the hydrogen chloride molecule the hydrogen and the chlorine each share one electron from the other atom to attain the the stable noble gas structure of helium for hydrogen and argon for chlorine.

the answer is d. 74.02

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
