explain in detail the formation of ionic compound calcium chloride with electron transfer diagram.
Answers
Ca=20
EC=2,8,8,2
Cl=17
EC=2,8,7
Ca transfer it's 2 electrons to Cl
to form Ca +2
Explanation:
Calcium has 20 electrons which can be written as 2,8,8,2. Thus Calcium has 2 valence electrons which it wants to give away to attain octet by having 8 electrons in its outermost orbit.
Chlorine has 17 electrons which can be written as 2,8,7. Thus Chlorine has 7 valence electrons and it wants to add one more electron in its outermost orbit to attain octet by having 8 electrons in its outermost orbit.
In Calcium Chloride molecule, there is one calcium atom and two chlorine atoms. Each Chlorine atom wants one more electron to complete its octet. So, two chlorine atoms will need two more electrons to complete their octet.
