What is the formula of the compound formed between chlorine and calcium? cacicicacaci2cica2

the formula  of the compound that  is formed  between  chlorine and calcium  is CaCl2

explanation

chlorine (non  metal)  react  with Calcium ( a metal)  to  form an ionic compound  CaCl2

Ionic compound   is formed when metal  loses electrons to form cation ( a  positively charged ion)  while  non metal  gains electrons  to  form anion (  a  negatively  charged ion)

An ionic compound is formed when calcium   metal(Ca) loses two electron to form   Ca2+ cation ,  while   2 chlorine atom  gain  one electron each to form cl- anions.

Therefore the formula  of ionic compound formed between chlorine  and calcium is CaCl2

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
