How many electrons are used to draw the electron-dot structure for calcium chloride (an ionic compound with the formula cacl2)?
1 answer:
Lewis structure is drawn in following steps,
1) Calculate the total number of electrons in valence shell of all elements,
Ca = 2
Cl = 7
Cl = 7
------------------------
Total valence electrons = 16
2) Draw central atom (Ca) in center surrounded by remaining elements (Cl) and draw a single bond between central atom and surrounding atoms. Subtract 2 electrons per bond from total valence electrons. And divide the remaining electrons on the most electronegative element. The structure will be as shown below,
Result:
So it required 16 electrons to draw the Lewis Structure of CaCl₂<span />
