Answer:
please mark me as brillent
Explanation:
the formula formed between :- Sodium and chlorine
Formation of sodium chloride (NaCl): In sodium chloride; sodium is a metal (alkali metal) and chlorine is non-metal. Sodium has one valence electron and chlorine has seven valence electrons.
the formula formed between :-Calcium and florine
Calcium fluoride. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF2.
Other anions: Calcium chloride; Calcium bromi...
Other cations: Beryllium fluoride; Magnesium fl...
Chemical formula: CaF2
the formula formed between :-Sodium and Oxygen
Sodium has a valency of 1+, which means it donates 1 electron in order to complete its octet. (Remember metals donate electrons, non-metals accept electrons). Therefore, in order to complete their outermost shells two Na atoms are required to bond with oxygen. Hence the formula is Na2O.
