Proton Saga

Science would not be where it is today if not for those who have devoted a great deal of their life to making new discoveries and figuring different aspects of the universe. Over 30 different scientists have added on the development of atomic theory, and made science changing discoveries that are still today quite impressive, even in comparison to modern day scientists. There are countless scientists involved in the evolution of atomic theory, but less than 50 have majorly impacted the way we view

The initial hypothesis of this lab was mostly refuted by the data with some exceptions. While most of the data showed that there was no true relationship between the number of valence electrons and the number of spectral lines, a few of the elements did prove to have said relationship. For instance, the elements Lithium, Sodium, Barium, and Potassium all had valence electron numbers that lined up with the wavelengths. Additionally, when reviewing the first graph, it is clear that there is no obvious

The race for an answer is over! All the scientists out there, put down your beakers and eyedroppers for just a moment and educate yourselves through this article. A new discovery in chemistry has shaken the science world as we know it. Joseph John Thomson, an incredible scientist living amongst us today has discovered a new negative particle, one he has appropriately named the “electron”. Now we’re sure all of you are asking the same question: How did he do it? And of course, we have the answer

The electron arrangement of an atom represents the particular orbitals in which are occupied by electrons in an atom. The relationship between the electron arrangement of elements and their position in the periodic table rely on an element's period, in which corresponds to the element's highest occupied energy level. This is due to periodic properties, this basically means that the elements properties are predictable based on their position within the periodic table. The periodic table is a result

The main components that make up copper are protons, neutrons, and electrons. Protons are positively charged, electrons are negatively charged, and neutrons don’t have a charge. The nucleus is at the center of the atom, and it contains protons and neutrons. Electrons are “stored” in energy levels. Since protons have a +1 charge and neutrons don’t have a charge, the nucleus is positively charged. The two stable copper isotopes that should be describe are 63Cu and 65Cu. The composition of 63Cu is 0

he atom or Atomos, which means uncuttable or indivisible, took many years to get to our understanding now. Back then they didn’t have the technology that we have now like microscopes, to figure everything out. Some important people who helped were Greek philosopher Leucippus and his student Democritus. They were the first came up with the idea that matter is made up of of tiny particles. They thought that if you cut something in half a lot times, that you will eventually reach a particle that can't

by a system of electrons, equal in number to the number of nuclear protons. It consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All electrons bind to the nucleus through an electromagnetic force. A ground of electrons bound together form individual molecules. An atom with an equal number of protons and electrons will hold a neutral charge. An ion has either a positive

report I will be analysing carbon 14 a radioisotope. A radioisotope is a radioactive isotope and isotopes are atoms that have the same number of protons but different number of neutrons in their nuclei. Carbon-14 is a radioisotope of the element carbon. Structure of Carbon 14- The diagram above shows the structure of carbon 14. Carbon-14 has six protons in the nucleus and six neutrons, giving carbon-14 an atomic mass of 12. It also has an extra two neutrons which makes the total eight neutrons

Atoms are made up of three tiny elements, a negative charge particles that spin around the shell outside of the nucleus, and it also consists of a protons that has a positive charge electron, and a neutrons that has neutral or no charge particles. Normally, protons and electrons balance each other by numbers to allow the atom acquire an electrically neutrally charge. The most easily shared electrons are the electrons furthest away from the nucleus of an atom. Ions are the atoms that are missing from

(Lucas & Wright, 2001) • Rutherford’s understanding of the atom was that the protons were clustered together in the nucleus. The nucleus is then surrounded by empty space occupied by electrons. (Lucas & Wright, 2001) 1897: James Johnson Thomson • Thomson discovered the electron. He used a cathode ray tube (an electron gun) with a
