The periodic table is a chart that organizes the elements based on their atomic properties. Elements in the periodic table are organized according to the periodic law. The periodic law states that chemical and physical properties of elements are periodic functions of their atomic numbers (the number of protons in the nucleus). As the atomic number of elements increases, different elements display similar characteristics at regular intervals.


Periodic law states that elements are arranged _______________________________________________________________.

a)

in alphabetical order.

b)

from largest to smallest.

c)

as periodic functions of their atomic numbers.

d)

there is no rhyme or reason.

26.

In 1869, Dmitri Mendeleev developed the first periodic table, organizing the elements according to atomic weight. When he ordered the elements, he noticed that there were patterns of repeating properties. The modern periodic table sequences elements from left to right by atomic number.
