No single scientist has devised the symbols of the elements. An organization called the International Union of Pure and Applied Chemistry (IUPAC) has determined the symbols of the elements on the Periodic Table.

Chemical symbols for compounds are written by combining the chemical symbols of the elements in the compound, along with subscripts to indicate the number of atoms of each element present. For example, water (H2O) is composed of two hydrogen atoms and one oxygen atom. The chemical symbols are always listed with the element that appears first in the compound listed first.
more electropositive element first, followed by electronegative elements
Chemical symbols of elements are formed by using one or two letters derived from the element's name in English or Latin. For example, the symbol for oxygen is "O," derived from its name. In some cases, the first letter of the element's name is used, while in others, the first and another letter are combined.
Auther Holmes is the Scientist who first proposed that theral convection in the mantle causes continental drift.

The scientist who first proposed that matter is made of atoms was John Dalton, in the early 19th century. Dalton developed atomic theory to explain chemical reactions and the behavior of gases.

A German scientist Alfred Wegener first proposed the idea of Continental Drift.

The first scientist to question the idea that atoms were indivisible was John Dalton, an English chemist, in the early 19th century. Dalton proposed that atoms were not actually indivisible, as previously believed, but rather could be rearranged in chemical reactions.
The chemical symbols are approved by IUPAC; symbols are derived from the name of the chemical element in Latin, frequently the first two letters.
