The correct option is A Elements are arranged by their atomic numbers.
The periodic table of elements, usually shortened to just the periodic
table is a tabular arrangement of the chemical elements, ordered by their
atomic number, electron configuration, and recurring chemical properties, whose
structure shows periodic trends. Generally, 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 the
halogens; and group 18 are the noble gases. Also displayed are four simple
rectangular areas or blocks associated with the filling of different atomic
orbitals.
