Resonance structure
Resonance
Potassium oxide (K2O) is an ionic compound, not a molecule, and does not have a Lewis structure.
Resonance
They run experiments that can determine the bond strength of a molecule.
CaCO3 does not have a lewis structure because this molecule is composed of ions. (Ca+2 and CO3-2). you have to draw the lewis structure of the ions separately, as shown in the parenthesis.
Calcium hydride, or CaH2, forms an orthorhombic lattice structure. For a Lewis structure of a single CaH2 molecule, simply place the Ca atom in the center single bonded to two H atoms.

Resonance
dots
resonance forms are individual lewis structure in cases where two or more lewis structure are equally good descriptions of a single molecule .
They run experiments that can determine the bond strength of a molecule.
Draw the Lewis Structure
The correct Lewis structure for a molecule of the compound C2H2 contains an alkyne bond. This is a triple bond between two C atoms. It has a linear bond geometry and no lone pairs.
The difference between the Lewis dot structure and the structural formula is that the formula only shows the bonds that have formed whereas the dot structure shows all the valence electrons, including lone pairs, in that molecule.
CaCO3 does not have a lewis structure because this molecule is composed of ions. (Ca+2 and CO3-2). you have to draw the lewis structure of the ions separately, as shown in the parenthesis.
Calcium hydride, or CaH2, forms an orthorhombic lattice structure. For a Lewis structure of a single CaH2 molecule, simply place the Ca atom in the center single bonded to two H atoms.
