At the Family Tree DNA Conference in November, James Irvine and Maurice Gleeson both presented sessions on utilizing a combination of STR and SNP data and various tools in analyzing their individual projects. Mauriceâs presentation was titled âCombining SNPs, STRs and Genealogy to build a Surname Origins Tree.â.
SO4 (2-) is a sulfate anion, and it has sulfur-oxygen single bonds. These single bonds are shorter than normal sulfur-oxygen single bonds but longer than a sulfur-oxygen carbon bond. This phenomenon is called resonance. C) SF6 has entirely covalent sulfur-fluorine bonds and is octahedral.D) CaI2 is an ionic compound, with the calcium and iodide ions in a lattice structure.O4 (2-) is a sulfate anion, and it has sulfur-oxygen single bonds.

There are two types of ionic binary compounds, Type1: The binary ionic compound in which cation can has only one form (charge), like Na+, Mg+2 and Al+3. Few examples of type 1 binary ionic compounds are as, NaCl, KBr, LiF, CaI2, AlF3, MgBr2 etc. Type2: The binary ionic compound in which cation can have the multiple forms (charge), like Fe+2 and Fe+3.
