<h3><em /></h3><h3><em>Please make sure to re-write this so your teacher doesn't think your cheating!</em></h3>

Explanation:

To write the Potassium electron configuration, we first need to know the number of electrons for the K atom (there are 19 electrons). When we write the configuration we'll put all 29 electrons in orbitals around the nucleus of the Potassium atom.

Draw four possible Lewis structures of the molecule xenon trioxide, XeO3, one each with zero, one, two, or three Xe−O double bon

algol [13]

Answer:

See the image below

Explanation:

To draw a Lewis structure of a molecule, you place the least electronegative atom (Xe) as the central atom, with the more electronegative atoms (O) surrounding it.

Then you distribute the electrons around the atoms, giving every one an octet and placing any extra electrons on the central atom.

This procedure gives you four possible Lewis structures, so the actual structure is a resonance hybrid of them all.

Structure D has no formal charges, so it is the major contributor.
