Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. ...
In a binaryioniccompound, one of the elements is Cl.Which of the following would the other element most likely to be? Cl I Mg Br Binary = two parts Since Cl-Cl would be covalent – not right and the same would be for the other halogens:I, and Br. Mg is a metal forms a cation...
barium has a reactivity similar to magnesium, calcium, and strontium. However, barium is more reactive than these metals. The normal oxidation state of barium is +2. Recently, research studies have found a +1 barium form as well. Barium can react with chalcogens in the form of exothermic ...
