A description of how to write the name for CaCl2 (Calcium chloride). First we determine whether CaCl2 is an ionic or molecular (covalent) compound using the periodic table. From the periodic table Ca is a metal and Cl is a nonmetal.Therefore CaCl2 is an ionic compound since it consists of a metal and nonmetal.Since CaCl2 is an ionic compound we name CaCl2 using the name for the metal (Ca) directly from the periodic table and then changing the element name Chlorine to Chloride.Therefor the name for CaCl2 is Calcium Chloride.ince CaCl2 is an ionic compound we name CaCl2 using the name for the metal (Ca) directly from the periodic table and then changing the element name Chlorine to Chloride. Therefor the name for CaCl2 is Calcium Chloride.
A covalent bond is a bond between two nonmetals, where the electrons are essentially shared. For example water is H2O. Oxygen needs two more electrons to have a full valence (â¦ outer shell) and each hydrogen needs one electron, so they share electrons to form the stable compound water.Cl (Hydrogen Chloride) is a covalent compound and forms a covalent bond. However, if water is added to hydrogen chloride, it forms hydrochloric acid which is an ionic compoun â¦ d that has ionic bonds. 2 people found this useful.
