- v. Answer true or false. (a) Mendeleev discovered that, when elements are arranged in order of increasing atomic weight, certain sets of properties recur periodically. (b) Main-group elements are those in the columns 3A to 8A of the Periodic Table. (e) Nonmetals are found at the top of the Periodic Table, metalloids in the middle, and metals at the bottom. (d) Among the 116 known elements, there are approximately equal numbers of metals and nonmetals. (e) A horizontal row in the Periodic Table is called a group. () The Group 1A elements are called the "alkali metals." (g) The alkali metals react with water to give hydrogen gas and a metal hydroxide, MOH, where “M" is the metal. (h) The halogens are Group 7A elements. (1) The boiling points of noble gases (Group 8A elements) increase in going from top to bottom of the column.arrow_forward5.
