Elements are the substances that make up everything in the universe, known and unknown. This means that elements are what make up matter, and everything you see, hear and touch. There are 118 elements known to man, some that you may know include gold, iron and oxygen. Each of these have distinguishing qualities and they come in 3 different states of matter, solid, liquid and gas. Some of these are man-made but most have been discovered. The things that make each element have a distinguished quality, is that they have different types of atoms.
Atoms are the basic building blocks of matter, and cannot be broken down to a further point. Each atom is made up of protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, while the electrons stay far apart from each other, and revolve around the center. This is called the Bohr model, made by Neil Bohr in 1913.
Neil Bohr was born on October 7th 1885. His father was a physicist and Neil graduated from Cambridge in 1911. His studies were theoretical, and the following year he worked in a laboratory in Manchester. It …show more content…
This shows the amount of electrons that one atom of an element has. Elements have very different qualities from one another like melting points, freezing points and boiling points. The element with the highest boiling point is Tungsten at 3143 Celsius, and the element with the lowest freezing point is Helium at -268.93 Celsius. They can look different from each other, and one could see this by looking all around them. Most of the elements that you see occur naturally, but some are manmade. Polonium and plutonium are examples of manmade elements. Elements like carbon, helium and nitrogen are one the most common in nature. All matter is theorized to come from the Big Bang, hydrogen being the first to form.
