ionic compound formulas\nan ionic compound made from calcium and chlorine,\nwhat is the formula for the ionic compound made from calcium (ca) and chlorine (cl)?\nca and is in group 2,\ncl and is in group 7a or 17,\ncl₂ca\nclca\ncacl₂\nca₂cl
Answer
Explanation:
Step1: Determine calcium ion charge
Calcium in group 2 loses 2 electrons, forming $Ca^{2 + }$.
Step2: Determine chlorine ion charge
Chlorine in group 17 gains 1 electron, forming $Cl^{-}$.
Step3: Balance charges
To balance the +2 charge of calcium, we need 2 chloride ions. So the formula is $CaCl_{2}$.
Answer:
$CaCl_{2}$
