two are lost
The combination of calcium, fluorine, potassium, and oxygen would form a salt compound. Specifically, calcium and potassium would lose their outer electrons to form Ca2+ and K+ ions, while fluorine would gain an electron to form F- ions. Oxygen would also gain electrons to form O2- ions. This could result in the formation of compounds like calcium fluoride (CaF2) and potassium oxide (K2O).
Negative ions form when atoms GAIN valence electrons.
The valence electrons of calcium will tend to give away electrons, as it is an alkaline earth metal with two valence electrons. This makes it more energetically favorable for calcium to lose these two electrons and achieve a full outer electron shell by forming a 2+ cation.
When calcium and oxygen combine to form calcium oxide, the individual properties of the elements do change. The new compound will have different chemical and physical properties than the original elements.
If two chlorine atoms attract electrons from two calcium atoms, they will form ionic bonds. The chlorine atoms will gain one electron each to achieve a full outer shell, forming chloride ions, while the calcium atoms will lose two electrons each to become calcium ions. The resulting compound will be calcium chloride, with the formula CaCl2.

Two electrons are transferred in the ionic bond between Calcium and Oxygen. Calcium (Ca) loses two electrons to form Ca2+ ions, while Oxygen (O) gains two electrons to form O2- ions, resulting in the transfer of two electrons in total.
When atoms lose or gain electrons, they form ions. These are charged particles.
Negative ions form when atoms GAIN valence electrons.
No. They gain electrons
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
The valence electrons of calcium will tend to give away electrons, as it is an alkaline earth metal with two valence electrons. This makes it more energetically favorable for calcium to lose these two electrons and achieve a full outer electron shell by forming a 2+ cation.
Iron can both gain and lose electrons depending on the reaction it is involved in. In general, iron tends to lose electrons to form positively charged ions, such as Fe2+ or Fe3+, but it can also gain electrons to form negatively charged ions, such as Fe2-.

No. Atoms of an element lose or gain electrons to form ions.
Yes, xenon can form monatomic ions, known as xenon ions. Xenon can lose electrons to form positively charged xenon ions or gain electrons to form negatively charged xenon ions.
