Periodic Table Groups Names. The periodic table today is arranged with two different parts, the groups and the periods. Select the group and identify the periodic table elements.
The number of each element corresponds to the number of protons in its nucleus (which is the same as the number of electrons orbiting that nucleus). Element groups are important because they can be used to predict the properties of elements based on their position on the periodic table. Common properties abundance in earth's crust
How many groups does the periodic table contain?
A classification system can have as many as 18 groups, if you're looking at the columns. The group number increases by one for every additional column, up to a maximum of 18. In the periodic table, the vertical columns are called ‘groups’ and the horizontal rows are called ‘periods’. Alkali metals are soft, ductile, and good conductors of electricity and heat.
