The two main types of chemical bonds are ionic and covalent bonds. To tell if Br2 is ionic or covalent (also called molecular) we look at the Periodic Table that and see that Br2 is made up of two non-metals. A compound formed as a result of two nonmetals reacting with each other and sharing electrons is called a covalent compound. So Calcium will lose its 2 electrons to 2 moles of bromine. Name common inorganic compounds using standard conventions and recognize the common names of frequently used substances. Ionic bond occurs when there is a complete transfer of electrons from one atom (metal) to another atom (nonmetal). These ions attract each other and formed the ionic compound CdBr2. In ionic bonding, more than 1 electron can be donated or received to satisfy the octet rule. The compound NCl3 is an ionic compound (metal and nonmetal), and therefore does not require prefixes- -so NCl3 is nitrogen trichloride. KNO2 (Potassium nitrite) is a yellowish white crystalline solid. Covalent compounds do not possess an electric charge which means covalent compounds are neutral. Classify compounds as ionic, covalent, or polar covalent bonds. If the difference is greater than 1.7, the bond will be ionic in nature.

Polarity occurs when the electron pushing elements, found on the left side of the periodic table, exchanges electrons with the electron pulling elements, on the right side of the table. When we have a non-metal and a non-metal the compound is considered non-polar covalent.Because we have a non-metal and non-metal in Br2 there will be no difference in electronegativity between the non-metal and non-metal. Group 18 elements, the noble gases, do not form ions. Bromine needs 1 electron to fill its outermost shell. Electronegativity is the measure of the ability of an atom to attract electrons in a chemical bond. Predict which of the following compounds are ionic and which are covalent, based on the location of their constituent atoms in the periodic table: (a) Cl2co (b) Mno (c) NCIS (d) CoBr2 (e) K2s (1) CO (9) CaF2 (6) CaO () IBI (k) CO2 3. i.
