Element M and X has to be determined from the given data. Concept Introduction: According to physical and chemical properties, the elements can be further divided into metals, non-metals and metalloids. In a group, the metallic character of an element increases from top to bottom whereas in a period, it decreases from left to right. Nonmetals are elements that usually contain 4-8 outer shell electrons. A nonmetal can be easily broken, that is they are brittle. They cannot conduct heat and electricity. Metals are elements that usually contain 1-3 outer shell electrons. They can conduct heat and electricity. Metals usually look shining and lustrous. K B r is a brittle white solid that conducts electricity on molten state or when dissolved in water. Potassium and bromide react to form K B r . The melting point of K B r is 734 ° C
