Atomic Structure Quiz Sample Questions 1. Why do only the number of protons and the number of neutrons make up the atomic mass of an element‚ but not the electrons? We generally do not use the number of electrons when calculating the atomic mass of an atom because they weigh so little (precisely 1/1836 AMU)‚ and only in precise calculations are the masses of the electrons included in atomic mass. 2. What was the difference between Mendeleev’s table and Mosley’s new arrangement? Mendeleev arranged

The Great Metabolic Race Metabolism comprises of a vital set of biochemical reactions that all living organisms require to sustain life. For a marathon runner‚ their physiological response to strenuous exercise depletes both their fats and carbohydrate storage in order to supply energy in the form of Adenosine Triphosphate (ATP). ATP is the energy form that the human body uses for biological processes such as movement and synthesis of biomacromolecules. In regards to running a marathon‚ the athlete

atom can move up and down the energy levels‚ one level at a time‚ and can never stop in between. Every hydrogen atom is made up of a single electron - proton system. Because the negative electron is attracted to the positive proton‚ potential energy is created inside the atom.<br><br>He figured that the farther away the electron is from the proton‚ the greater the potential energy is inside. In conclusion‚ since hydrogen atoms emit light energy in specific frequencies‚ the hydrogen atom must be within

puzzle made of smaller pieces. After the discovery of the electron and proton as subatomic particles J.J. Thomson had started to discover atomic theory that gave a complete explanation of atomic structure. According to Thomson protons are embedded in the atoms like a water melon and electrons are present in atoms to make the atom electrically neutral. He called this the “plum pudding” model‚ in the model the electrons and protons are uniformly mixed throughout the atom. His discovery of atomic theory

As positively charged particles (protons) move from the inter-membrane of the mitochondria into the first chamber and are pumped into the matrix‚ a charge that can power the axle rotation is generated. This charge occurs because the protons are moving back and forth from an area of high concentration‚ i.e very crowded‚ to an area of low concentration‚ i.e not crowded. With this continuous proton movement‚ the axle has enough power to rotate‚ as its rotating a reaction
