Periodic Table Essay

How are the heavier naturally-occurring elements in the Periodic Table formed? Light elements are formed through the process of fusion of nuclei in stars and provides the energy to counter the gravitational attraction through outward pressure. Hydrogen is the first of the elements that will fuse either via the proton-proton chain reaction, in which hydrogen fuses to form helium or the CNO cycle where carbon, oxygen and nitrogen act as catalysts in the fusion of hydrogen. Since these 3 elements are

Periodic Table Research Paper Madison Swanson Manson Northwest Webster Abstract Today, the periodic table is used by many people worldwide to learn more about the elements located on it. It has evolved into a much easier piece of information to use because of all the many scientists and chemists that have revised it over the last hundred ish years. There are certain things on the periodic table that help to learn more about each element. Periodic families are used to help understand similarities

on the periodic table so without it there would be no chemistry. It has forever changed how people learn about and understand the elements and chemistry itself. The periodic table is named this because the elements are placed into periodic groupings based on their relations to one another. The periodic table has changed a lot over the years in order to develop into the periodic table used today. Hundreds of years have gone by and many people have contributed to creating the periodic table. A lot

The Periodic Table contains 118 elements, all different with shape, size, and what it’s made up of. Out of the 118, 3 were chosen and they will be discussed later in this paper. Those elements are Potassium, Sulfur, and Krypton. The first is Potassium. Potassium was first discovered and isolated by Sir Humphrey Davy, a Cornish chemist and inventor, in 1807. Potassium is highly reactive, but Davy isolated the element through a process what’s called electrolysis, a process by which an electric current

The periodic table of the elements was published in 1869 by Dmitri Mendeleev. He shows the elements in order according to the atomic weight. A pattern where similar properties for elements occur periodically. With the work of of the physicist Henry, the periodic table was known on the basis of increasing atomic number rather than an atomic weight. This table can be used to predicts the properties of elements that had not been discovered yet. It lists elements, in other words number of protons in

Explain how an element’s group in the periodic table can be used to predict its outer shell electrons. (3 marks) The element’s group in the periodic table predicts how many electrons are in it’s outer shell. For example, Sodium is in group 1, and has one electron in its outer shell. For elements in groups 13-18, the last digit of the group predicts how many electrons in its outer shell. For example, silicon is in group 14 and has 4 electrons in its outer shell. This does not apply to groups

Interpreting the Periodic Table Lab Report Name: Kelsey Cordero and Bruno Canteros Lab Partners: Ashley Fernandez, Lab Experiment: Interpreting the Periodic Table Date: January 15, 2015 Introduction: The periodic table is the most important chemistry reference there is. It arranges all the known elements in an informative array. Just like when entering a grocery store similar items are grouped together which makes an item easier to find. Elements are arranged left to right and top

Dmitri Mendeleev, who developed the periodic table of the elements, was one of sciences most influential leaders. Before Mendeleev, religion and beliefs shaped people’s choices rather than science and facts. Mendeleev’s fame and dedication changed that. Throughout his life, Mendeleev was a leader in science and the legacy he left behind led others to discover new elements and facilitate chemistry for generations to come.   Dmitri Ivanovich Mendeleev was born on February 8th, 1834 in Tobolsk, Russia

How was the Periodic Table Discovered? The periodic table is one of the most known things in science. It has elements, metals, non-metals, solids, liquids and gases. The beginning of the periodic table starts back in 1669 when a German merchant and alchemist named Hennig Brad began creating a Philosophers Stone. He then discovered Phosphorus. A few years later in 1809 47 elements had been discovered, in 1863 chemist John Newlands began forming the elements in groups and discovering more which was
