What are the exceptions in the Periodic Table?

$\huge\mathcal\colorbox{cyan}{{\color{white}{AŋʂᏯɛཞ♡࿐}}}$

The periodic table is composed of seven horizontal rows or periods and is numbered between 1 to 7. There is a regular gradation in the properties of elements in the horizontal rows(periods) from left to right. The periodic table is composed of eight vertical columns or groups. They are numbered between 1 to 8.

What are the exceptions in the Periodic Table?

$\huge\mathcal\colorbox{cyan}{{\color{white}{AŋʂᏯɛཞ♡࿐}}}$

Exceptions to the States of the Periodic Table

Mercury. The shiny metal Mercury at room temperature unlike all metals in the periodic table exists as a liquid.

Bromine. Again another liquid in the periodic table, located in Group 7 Bromine is the only other known liquid in the periodic table.

3→ Halogens are highly reactive nonmetallic elements in group 17 of the periodic table. As you can see in the periodic table shown in the Figure below, the halogens include the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). ... As a result, it is one of the least common elements on Earth.
