different elements absorb and emit different wavelengths of light. (2) Gamow thought that nuclear fusions took place in the first minutes after the Big Bang‚ because he assumed that the initial components of the universe would have been seperate protons‚ neutrons and electrons. He hoped that they could build bigger atoms by fusion in the heat of the Big Bang‚ because nucleosynthesis‚ which

Electron Transfer /Chemiosmosis: the movement of protons (H+) down a concentration gradient through ATP synthase that can HARNESS THE ENERGY OF THAT GRADIENT (proton-motive force) to bond ADP and phosphate to create ATP through oxidative phosphorylation * Occurs during the Light Dependent Reaction * 90% of ATP is produced this way

Modern theories For a long time‚ it was thought that the proton‚ neutron‚ and electron were the elementary particles‚ as well as the smallest. Since the Atomic Theory was formulated‚ many new particles have been discovered. The new theories concerning these particles and predicted particles attempts to explain every phenomena in physics. This is also called the Universal Theory of Matter. Dark Matter and Dark Energy Dark matter is an assumed kind of matter which unlike ordinary matter does

Isotopes are different types of atoms (nuclides) of the same chemical element‚ each having a different number of neutrons. In a corresponding manner‚ isotopes differ in mass number (or number of nucleons) but never in atomic number.[1] The number of protons (the atomic number) is the same because that is what characterizes a chemical element. For example‚ carbon-12‚ carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12‚ 13 and 14‚ respectively. The atomic number of carbon

1. Atomic and Molecular Structure a. Students know how to relate the position of an element in the periodic table to its atomic number and atomic mass. The Periodic Table organizes elements by their atomic number - from hydrogen (1) to whatever is the highest one currently known (>105). It is arranged so that similiar members fall in a list such as Chlorine Bromine etc.. The average atomic weight is usually shown with each element‚ but due to isotopes (caused buy nuclear varations)

(0 net carbon emission) The fundamental physical components of a typical dual-chamber MFC are the electrolyte‚ an anode and a cathode partitioned by a proton exchange membrane as shown in figure1 (Du‚ Li and Gu 2007). At the anode‚ microbial respiration oxidizes available substrates to carbon dioxide results in liberation of electrons and protons. These electrons are transported out of the cell to the electrolytes via electrochemically active carriers‚ also known as

difference between atoms of different elements. - The number of protons in an atom determines the element to which the atom belongs. - The atomic number of an element shows: * The number of protons in the nucleus of an atom of the element * The number of electrons in the neutral atom of that element * The position of the element in the Periodic Table Mass number (A) - For any atom‚ the mass number is the sum of the number of protons and the number of neutrons.

Effect of ions on living organisms (24 marks) An ion is a charged atom or molecule. This is because it does not have an equal amount of protons and electrons‚ therefore giving the atom an overall charge. An example of an ion is ‚ this is sodium and the plus sign represents an overall positive charge. Ions are very important to living organisms as they are essential for life‚ they play an important role within the cell allowing mechanisms within the living organisms such as respiration‚ to take
