A row of elements is known as a Period, while a column is known as a group, or family.
The horizontal row on the periodic table is called the "period". The vertical column is called the "group".
A row on the periodic table is a horizontal arrangement of elements that share similar properties. These elements have the same number of electron shells. Each row represents one energy level or electron shell in an atom.
The gradual changes in properties across a row in the periodic table are called periodic trends. These trends include atomic size, ionization energy, electron affinity, electronegativity and metallic character.
