Science Periodic Table Essay - 700 Words.
The Periodic Table Chemically speaking, the periodic table was a major factor in improving the study of elements, in which then the study of these elements expands into broader studies such as atoms and sub-atoms. This essay will talk about the history of the development of the periodic table and will further discuss the how and why it was created.The periodic table consists of elements that are grouped together based on the knowledge that the elements have similar properties. The periodic table is arranged by periods and groups. The atomic number usually increases when moving across a row or period. The atomic structure of an atom consists of an electron, a proton, and a neutron.Atomic radius is the physical size of an atom while ionization energy is the energy required to completely pull one electron away from an atom. When it comes to the periodic table, there are accepted periodic trends for both atomic radius and ionization energy.
The periodic table orders elements by increasing atomic number, which is the number of protons in the atom of an element. The rows of the periodic table are called periods. All elements within a period share the same highest electron energy level. The columns of the periodic table are called groups.The history of the periodic table is a long and intriguing tale. But to get to our modern day periodic table we first must know what elements themselves are and how they are made up. There are many contributions from different scientists throughout the ages, such as Aristotle or Democritus.
Everything in the universe contains the atoms of at least one or more elements. The periodic table lists all the known elements and groups together those with similar properties. A case study video.
