The Lewis structure of CaO involves a calcium (Ca) atom with two valence electrons and an oxygen (O) atom with six valence electrons. The Ca atom donates its two valence electrons to the O atom, forming a bond. This results in a compound with a calcium cation (Ca^2+) and an oxide anion (O^2-).
In a CaO molecule, there are a total of 16 electrons: 10 electrons from calcium (Ca) and 6 electrons from oxygen (O).
In calcium hydroxide, the bond between calcium and hydroxide ions is ionic because calcium loses electrons to form a cation and hydroxide gains electrons to form an anion, resulting in electrostatic attraction. The bond within the hydroxide ion (O-H) is covalent, as the oxygen and hydrogen atoms share electrons to form a stable molecule.
Since calcium (Ca) is in Group 2 and oxygen (O) is in Group 16, the electron configuration for Ca is [Ar]4s² and for O is [He]2s²2p⁴. Calcium will lose 2 electrons to achieve a stable electron configuration of [Ar], while oxygen will gain 2 electrons to achieve a stable electron configuration of [He]2s²2p⁶. The electron shell diagram for calcium oxide (CaO) will show the transfer of these electrons from calcium to oxygen, resulting in Ca²⁺ and O²⁻ ions being attracted to each other electrostatically.
Ionic bond. Calcium (Ca) will lose two electrons to become a positively charged ion, while oxygen (O) will gain two electrons to become a negatively charged ion. These opposite charges will attract each other, forming an ionic bond between the two atoms.
Answers: oxygen, fluorine, oxygen, sulfur.
Ca has 2 electrons in outer shell (valence electrons) and O has six. Because of this, Ca loses 2 electrons which O gains, and Ca becomes a Ca2+ ion, and O becomes an O2- ion. These then bond to form CaO. Ca2+ + O2- → CaO

H, He, Li, Be, C, N, O, F, Ne, Na, etc to Ca. After Ca all have electrons in a d orbital.
An example is calcium(11)oxide. Ca^2+ cation interact with O^2- anion

Ionic bond. Calcium (Ca) will lose two electrons to become a positively charged ion, while oxygen (O) will gain two electrons to become a negatively charged ion. These opposite charges will attract each other, forming an ionic bond between the two atoms.
No, MgO forms an ionic bond because magnesium (Mg) loses electrons to oxygen (O), resulting in the formation of Mg2+ cations and O2- anions. This complete transfer of electrons creates an electrostatic attraction between the ions, making MgO an ionic compound.
The bond between Ca and O in calcium oxide (CaO) is considered ionic. Calcium, being a metal, donates electrons to oxygen, a nonmetal, resulting in the formation of ions with opposite charges that are attracted to each other.
Length: C = O < C − O; Strength: C = O > C - O; greater number of electrons between nuclei pull atoms together and require greater energy to break the bond.
