CaCl2 is an Ionic molecule. With Electronegativities of 1.00 and 3.16, a difference of 2.16, this falls into the category of Ionic Bond.
The scale I have always used is 0-0.39 Non Polar Covalent, 0.4-1.79 Polar Covalent and 1.8 and Up Ionic. If you have a sample to test, you could heat it on a hot plate, Ionic compounds don't melt too well, you could also dissolve it in water as ionic compound typically dissolve well in water.
Depends. If you mean Chlorine, which goes around as Cl2, then no because electron cloud density is evenly shared in the covalent bond as they are both equally as electronegative.
If you mean Chloride compounds, then usually the answer is yes since Chlorine is a highly electronegative substance that strongly attracts the electron cloud density to it to create a permanent dipole.
Neither, calcium chloride, CaCl2, is ionic. (Metal and non-metal)
Calcium carbonate forms a ionic lattice. It is not a covalent compound.
Yes
The bonding in calcium fluoride (not "flouride") is ionic, not covalent.
NH3 is a polar-covalently bonded compound.
Calcium Phosphate is very polar because it is an ionic compound.
The name of the compound Na2CO3 is sodium carbonate. It has: 2 atoms of sodium (Na) 1 atom of Carbon 3 atoms of Oxygen bound together with ionic and polar-covalent bonds
Polar Covalent
The answer to this question is somewhat strange. Calcium Bromide is an Ionic compound therefore the terms polar and nonpolar don't really apply because there is no bond. There are however two completely different charges between the atoms therefore making it, in a sense, the strongest kind of polar molecule- an ionic polar. So Calcium Bromide is Polar.
Calcium carbonate (CaCO3) is an ionic compound (to some extent) , all ionic compounds are polar.
Methanol is a polar covalent compound.
It is not possible for the polar covalent compound to have a lower melting point than the non-polar covalent compound because they have ionic bonds.
The bonding in calcium fluoride (not "flouride") is ionic, not covalent.
I2 is a non-polar covalent compound.
Yes a compound can be both if it has polar bonds that are not matched on the opposite side by the same polar bond.
Zinc carbonate is ionically bonded, which could be viewed as maximally polar, but "polar" in chemistry is usually reserved for a description of covalent bonds.
No. sulphur dioxide has polar covalent bond and is a polar covalent compound.
N2 is non-polar covalent compound
Calcium and lithium individually are both elements with metallic bonding and not any of polar, covalent, or ionic bonding. They could be described as non covalent.
The formual is suspect- such a compound would be covalent.
