How are the elements arranged on the periodic table?
The periodic table is a chart showing all the elements arranged in order of increasing atomic number. The vertical columns in the periodic table are called groups.
How did Mendeleev make the periodic table two dimensional?
Mendeleev – He made the table two-dimensional rather than a list. He arranged the elements in order of atomic weight but had the Newlands Octave elements underneath each other. The vertical columns are called groups and the horizontal rows are called periods. The term periodic refers to the fact that the properties swing to and fro like a pendulum.
Why are the vertical columns on the periodic table called periods?
The vertical columns are called groups and the horizontal rows are called periods. The term periodic refers to the fact that the properties swing to and fro like a pendulum. Some elements had not been discovered at the time of Mendeleev writing up his table so he left gaps to indicate where elements ought to be.
