Cual es la razón de que la molécula de oxigeno de calcio sea caO y no sea ca2O. o caO 2

In calcium oxide (CaO), oxygen and calcium are respectively a non-metal and a metal, whose bonding is based on the exchange of electrons to form an ionic bond, which balances their charges and makes it chemically stable.

Explanation:

What is the reason that in the calcium oxide molecule is caO and not Ca₂O or CaO₂?

Calcium is a metallic element -a soft metal- that is capable of bonding with a non-metallic element such as oxygen to form an ionic bond, so that each Ca atom will bond to a single O atom.

CaO (calcium oxide)

          Ca              +         O       ---→       Ca⁺²    +      O ⁻²

     2   8    8   2               2   6                  2  8   8       2  8

The electron exchange that is observed occurs between +atom and atom, and for this reason the chemical formula of calcium oxide is CaO.

Calcium oxide (lime) is obtained by heating calcium carbonate (CaCO₃) to very high temperatures through the following reaction

                                CaCO₃ + heat → CaO + CO₂

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the dependant variable is spilled water

the independent is the heat
