Chemistry is one of the most fascinating and enormous fields in science. It deals with the
study of matter, how they react and interact. It can be said that it is an interesting yet
difficult subject that is taught in academic institutions. However, chemistry plays a
significant role in our daily lives for everything that we see, touch, smell, and use are
composed of tiny particles that make up the elements.
The most known instrument in the world of chemistry is the so-called Periodic Table of
Elements. The periodic table of elements contains the data of all chemically known
elements in an orderly manner. Furthermore, periodic tables are colored to classify the
necessary information such as the type of the element.
Referring to the Figure 1, the most basic part of a written element is denoted b

addition to this, element name is commonly formed based on the of element is identified
discoverer, where was it discover, planet’s name and other factors
of naming.
b – the atomic number
The atomic number can be identified by the number of protons present in the
nucleus. With this, an element can be known according to the atomic number: the
element with the least proton comes first while the element with the most protons
comes last.
c – the atomic weight
The atomic mass, also atomic weight, refers to the quantity of protons and neutrons
altogether present in a nucleus of an element. It is also the average weight of all the
isotopes of one atom.
Let us take a closer look of the origin and the first element that was born.
The expansion of the Big Bang approximately 15 billion years ago, gave birth to the first
atomic particles. The hot dense state of the universe never allowed quarks, electrons, and
protons to combine until the cool down of the Big Bang. Particles are bumping into each
other, later the formation of nuclei composed of protons and neutrons. While time is
passing by, the cool down allowed stable atoms to form where nuclei attracts electron to
orbit and nuclear reactions of these atomic particles formed the first stars.

in the universe. When one electron started orbiting one proton,
