is cacl2 electrovalent compound
Answers
Answer:
CaCl2 or Calcium Chloride is an ionic bond and not a covalent bond. Since there should be sharing of electrons between two atoms to be a covalent bonding. In case of calcium chloride, the calcium gives up an electron to each chlorine atom, becoming Ca2+ ions and chlorine become Cl– ions.
Step-by-step explanation:
An ionic bond is formed between a metal and a nonmetal. Calcium is in group 2 on the periodic table (an alkali earth metal), and has a +2 charge. Chloride is from the halogens which has a -1 charge (halogens are non metals).
The other way to determine the bond character is to use the electronegativity values from a chart. Chlorine has a value of 3.0 and Calcium a value of 1.0. Subtract and find the absolute value, and you get 2.0.
The scale you use is 1.8-2.9 is an ionic bond, 0.5-1.8 is polar covalent, and 0.0-0.4 is nonpolar covalent. So in that regard, CaCl2 is ionic.
