Our electronegativity difference calculator uses the above formula. To tell if SO2 (Sulfur dioxide) is ionic or covalent (also called molecular) we look at the Periodic Table that and see that S is a non-metal and O is a non-metal. What is electronegativity? Write the correct name for these compounds. It was discovered in 1934 by Denbigh and Whytlaw-Gray. Biochemical Nomenclature and Related Documents, London:Portland Press, 1992. /**/, /**/, /* Ca2+ + CO32- --> CaCO3, 2.D; FeO --> Fe + O2- --> Iron must have a charge of +2 to make a neutral compound --> Fe2+ + O2- --> Iron(II) Oxide, 3.A; Al(NO3)3 --> Al3+ + (NO3-)3 --> Aluminum nitrate, 4.B; Phosphorus trichloride --> P + 3Cl --> PCl3, 5.D, LiClO4; Lithium perchlorate --> Li+ + ClO4- --> LiClO4, 6. a. Beryllium Oxalate; BeC2O4 --> Be2+ + C2O42- --> Beryllium Oxalate, b. Strontium is a type I cation and there is no need for a Roman Numeral. The two main types of chemical bonds are ionic and covalent bonds. The anions are all of the first type, and gain electrons until they have the same number as the nearest noble gas. Such acids include sulfuric acid (H2SO4) or carbonic acid (H2CO3). There are ionic compounds which is a compound formed by a positive metal ion and a negative nonmetal ion.
