mendeleev's name for a column of elements was groups.
Chemical properties as they possessed the same number of valence electrons, leading to similar reactivity and bonding behavior. This organization allowed Mendeleev to identify patterns and predict the properties of undiscovered elements.
Columns are also known as Groups or Families. Rows are also known as Periods or Energy levels
The elements in column 13 of the periodic table (Group 13) typically have an oxidation number of +3 in their compounds. This includes elements such as boron, aluminum, gallium, indium, and thallium.
Elements in the same column, or vertical column, are known as "group" or "family." Each group contains elements with similar chemical properties due to their shared number of valence electrons.
there are 36 electrons in a valence shell. -cmoney

He left too many spaces between the elements......
Yes, this affirmation is true.
Mendeleev predicted the name "eka-aluminium" for the element that is now known as gallium. This naming convention was based on the positions of the elements in his periodic table.
