Which of these chemical elements is represented on the atomic table by a single letter?

Each element is grouped on the periodic table according to its different chemical properties. These differences are based on the number and spatial distribution of electrons in an atom's outermost orbital shell. Electrons in the outermost orbital can be shared with atoms of other elements, resulting in chemical bonding. Alternatively, they can be exchanged in a form of ionic bonding. The periodic table, devised by Dmitri Mendeleev in the 1860s, organizes these elements into rows and columns, with each row representing a specific element's atomic number.

Elements with similar properties are grouped together in rows called periods. Each period has a different length, with the first period consisting of two elements (hydrogen and helium), the second having eight elements, and so on. The elements within each period are also grouped into columns, which have specific names such as the alkali metals, the halogens, and the noble gases.

Most of the elements have a symbol that relates to their English name, but there are exceptions. For example, silver is denoted by the symbol Ag derived from its Latin name argentum, and mercury is symbolized by Hg based on its Latin name hydrargyrum.

All of the 118 elements in the periodic table are composed, microscopically, of individual atoms. However, most of them also exist as a combination of two or more atoms in a molecule. To represent a molecule on the periodic table, we add a subscript to the element's symbol. For example, oxygen is represented by O2 because it consists of two atoms of oxygen joined together.
