What happens to the electrons of metal elements when forimg ionic compound with nonmetals?
Generally the electrons are transfered from the metal elements to the nonmetalic elements so that both form stable electron configurations. For example, in sodium chloride one sodium atom loses an electron so that it has the stable electron configuration of Neon and chlorine gains one electron so that it has the stable electron configuration of Argon. This results in negativley charged chlorine atoms and positively charged sodium atoms which are then attracted to each other and form the ionic bond. Having a lot of those atoms and therefore a lot of those bonds gives an ionic compound. Generally no bonds are fully ionic or covalent; they have what is called percent ionic character that is a measurement of how much the bond resembles an ionic bond rather than a covalent bond (in covalent bonds electrons are shared between the atoms).

when forming ionic compound , they want to gain or lose the smallest number of valence electron.
Metal like Sodium Chloride. Sodium is the Metal and Chloride is the Nonmetal.
ionic bond is formed.
Every row of the periodic table is the beginning of another shell. and as you go left to right on any row, every square adds an electron. 1 electron in the outer shell would… be something like Hydrogen or lithium, or sodium. 2 electrons in the outer most shell would be Beryllium, Magnesium, or Calcium for example. And these are all metals . The exception to this is Helium, which has 2 electrons in its outer shell, but the first shell is an exception on this rule.
it attaches to the nonmetal
It becomes a cation - loses electrons
Ionic reaction or chemical reaction generally
Generally so because the electronegativity of the nonmetal far exceeds the metal's electronegativity and thus the nonmetal will " pull " the electron(s) into it's valance shel…l.
The electrons form an Ionic Bond, which is essentially an electrical attraction between opposite charges.
At least one, and usually all, of the valence electrons of the metal atom is donated to the valence shell of the nonmetal atom.
Compounds between metals and nonmetals are predominantly ionic because there is a large difference in electronegativity between most metals and most nonmetals.
When cesium reacts with oxygen to form an ionic compound each metal atom loses 2 electrons and each nonmetal atom gains?
Each caesium atom loses an electron and the oxygen atom gain twoelectrons (for Cs 2 O).
The more electronegative atom gains electrons from the other and fills its valence shell. The other atom loses all electrons in the outermost shell (there are many exceptions …when it comes to transition elements) and obtain the stable configuration in the previous shell.
If the electrons are "stolen" from the metal by the nonmetal, anionic bond is formed. If the electrons are shared between the metal and the nonmetal, acovalent bond is formed.… If the electrons "resonate" between the metal and the nonmetal, aresonance bond is formed.
It is true of binary ionic compounds but not necessarily ofcompounds containing polyatomic ions.
