Answer:The levels of classification are as follows (Broadest to
narrowest): Domain, Kingdom, Phylum, Class, Order, Family, Genus,
Species
Explanation:
VB theory does not indicate that the diatomic molecule He₂ is a viable species.
Helium has atomic number 2, it has 2 protons and 2 electrons.
Electron configuration of helium atom: ₂He 1s².
Helim (He) is a noble gas.
Noble gases (group 18) are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.
Noble gases have very stable electron configuration and does not need to gain electrons, only when they gain energy.
Valence bond (VB) theory explains chemical bonding.
Helium atom is stable and does not form molecule.

Answer:
I think b is the correct answer
Answer:
Is this must be multiple choice Put where where's the stuff
Explanation:
no explanation for you
The density will become less, this is because thing with less density float to the top when things with more density float to the bottom. It also becomes colder.
