No. It only has ionic bonds.
Compounds with both ionic and covalent bonds contain polyatomic ions.
No, NH3 contains only covalent bonds.
Yes it does.
CCl4 is a covalent bond. Their difference in electronegativity isn't that great
Calcium cyanide contains both ionic and covalent bonds: There are calcium cations and cyanide anions, and the cyanide anions contain internal covalent bonds, specifically triple bonds between carbon and nitrogen.
Calcium has both ionic and covalent bonds.
Ionic and covalent bonds both result in a full outer electron shell.
A nonbinary ionic compound. Covalent bonds are molecular - nonmetal.
Fluorine forms both ionic bonds and covalent bonds, the former being more common.
Bonds aren't strictly covalent or ionic - it's a whole grey area. CaOH2 probably has bonds with both covalent and ionic properties.
The first is covalent bonding, the second is ionic bonding. Both involve ions. Google 'covalent' and 'ionic' for specific definitions. :)
The bonds in stannous choride are polar covalent.
