The alkali metal, halogen, transition element, noble gas, lanthanide element, actinide element and alkaline earth metal, from the given elements, are to be determined. Concept introduction: The substances that cannot be degraded into any other simple substances are known as elements. Metals are solid materials used to conduct electricity. Metals are used in making jewelry, coins, and decorative art. Metal alloys are used in building structures and vehicles. Examples of metals include cadmium, zinc, mercury, aluminum, gold, tin, silver and many more. Alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table also known as S-block. The halogens are five non-metallic elements found in group 17 (VIIA) of the periodic table. Transition elements are the elements categorized between the S-block and P-block elements of the periodic table. Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. Lanthanides are the elements that fall under the lanthanum family. They are usually shown in the periodic table as the first row in a separate block, underneath the transition metals. Actinides are the elements that fall under the actinium family. They are usually shown in the periodic table as the second row in a separate block, underneath the transition metals. Alkaline earth metals are the elements that lie in group 2 (IIA).
