Which compound most likely has atoms held together by covalent bonds? A. Methane, CHA

B. Lithium fluoride, UIF

C. Sodium chloride, Naci

D. Magnesium chloride, MgCl2

Alpha particles have positive charge, beta particles have negative charge, and answer 4 just doesn’t make sense. thus, you are left with only one possible answer.

You know how the first one if filled up like the objects do the same but with the other categories

Mistures i think, hope it

A- electron repulsion favors a tetrahedral shape, so the orbitals are 109.5° apart from each other. of a hydrogen atom on methane. they may also contain lone pairs—this explains the geometry of water, which is sp3 hybridized due to the lone pair, which occupies one of the four hybrid orbitals.
