   The vertical columns of the periodic table are called groups. According to the IUPAC system of naming groups, there are 18 groups, with the group number ranging from 1 to 18. The elements in each group have the same number of valence electrons and hence, have similar chemical properties determined by the outermost electrons.

   All the elements of the periodic table are arranged in order of increasing atomic (proton) number. The table was named the periodic table because similar properties occur at regular intervals. Elements with similar properties are in columns called groups. Elements to the left of this line are metals. Elements in the same group of the periodic ...

   How did Mendeleev organize elements?

   • He then arranged the elements by putting those with similar properties below each other into groups. To make his classification work Mendeleev made a few changes to his order: group A vertical column in the periodic table containing elements with similar chemical properties. Mendeleev left gaps in his table to place elements not known at the time.

   Why did Mendeleev leave gaps in the periodic table?

   • group A vertical column in the periodic table containing elements with similar chemical properties. Mendeleev left gaps in his table to place elements not known at the time. By looking at the chemical properties and of the elements next to a gap, he could also predict the properties of these undiscovered elements.

   When were elements first classified?

   • The earliest attempt to classify the elements was in 1789, when Antoine Lavoisier grouped the elements based on their properties into gases, non-metals, metals and earths. Several other attempts were made to group elements together over the coming decades.

   When did chemist Dmitri Mendeleev create the periodic table?

   • Scientists had a rudimentary understanding of the periodic table of the elements centuries ago. But in the late 19th century, Russian chemist Dmitri Mendeleev published his first attempt at grouping chemical elements according to their atomic weights.
