WebGenerally, within one row (period) the elements are metals to the left, and non-metals to the right, with the elements having similar chemical behaviours placed in the same column. Table rows are commonly called periods and columns are called groups. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are ... Web5 de nov. de 2024 · As you move down an element group (column), the size of atoms increases. This is because each atom further down the column has more protons and neutrons and also gains an additional electron energy shell. As you move across an element period (row), the overall size of atoms decreases slightly.
WebIn a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group).
