The bonding between K^+ ions and F^- ions in potassium fluoride is covalent ioni

Question

The bonding between K^+ ions and F^- ions in potassium fluoride is covalent ionic nonpolar polar Sulfur forms a simple (monatomic) ion with a charge of 6- 2- 2+ 6+ Magnesium forms a simple (monatomic) ion with a charge of 2- 2+ 4+ 8+ The formula of the ionic compound formed by magnesium and bromine is MgBr Mg_2Br MgBr_2 Mg_2Br_3 The correct name for Lil is indium lithide iodine lithide lithium indide lithium iodide The bond in Br_2 is double covalent ionic single covalent triple covalent The correct name for I_2O_5 is diiodine pentoxide diiodopentoxide iridium pentoxide pentaoxodiiodine When HC1 is formed, a Cl atom gives one valence electron to an H atom an H atom gives one valence electron to a Cl atom a pair of valence electrons is shared, one each from the H atom and the Cl atom a pair of valence electrons is shared, none from the H atom and two from the Cl atom The Lewis formula for CCI_4 has 0 lone pairs 1 double bond 4 ionic bonds The correct Lewis formula for carbon dioxide is

Explanation / Answer

19) ionic

20) 2- monoatomic sulfur will form ion with charge 2-

21) 2+   monoatomic Magnesium will form ion with charge 2+

22) MgBr2   Mg has +2 valency and Br has -1 valencey so Mg2+ and 2Br-
