Periodic table. Columns are called groups. Elements in the same group have similar properties. Rows are called periods. Groups (vertical) 1A = alkali metals. 2A = alkaline earth metals. 7A = halogens. 8A = noble gases. Element: A substance made of atoms of one element. Compound: A substance made of atoms of 2 or more elements chemically bound ...
Periodic Table of Elements Exercize
Vertical columns on the periodic table represent families of elements with similar chemical properties called . groups. What are known as the main group or representative elements are designated by the numbers 1A through 8A (Group A elements). The elements known as . transition metals (Group B elements) span the distance between groups 2A and 3A.
