Fast what bond transfers electrons Atoms, Elements, and Compounds - ppt video online down - 13 forces – electromagnetic force electrons (-) are interested in the protons ( ) within the nucleus due to the distinction in electric powered price. Momentum (kinetic electricity!) Maintains electrons from falling into the nucleus electrons “orbit” the nucleus just like earth orbits the sun. 2 forming chemical bonds the force that holds two atoms collectively is known as a chemical bond . The valence electrons are the electrons worried in forming chemical bonds. Factors have a tendency to react to acquire eight electrons. That is name a solid octet. Noble gases (group viiia/18) have this shape (octet) and are inert (does now not form bonds). Atoms can gain, lose, or share electrons to attain an octet. 15 how are factors extraordinary? atoms of various elements include unique numbers of protons inside the nucleus. Because the number of protons is so essential, it is referred to as the atomic range. Every detail has a completely unique atomic wide variety. 7 early version of the atom in 1897 english physicist j. J. Thomson located debris that were too small to be atoms. Those poor particles had been in the end referred to as “electrons.?? thomas idea the electrons have been evenly disbursed within the atom, like raisins in bread. (Bread , raisins – ). 10 internal an atom protons and neutrons are an awful lot large and more massive than electrons. The mass of the nucleus determines the mass of an atom. The electrons surround the nucleus and shape the electron cloud.
5 structure of the atom for you to understand atoms, we need to apprehend the concept of electrical price. We realize of two distinctive varieties of electric powered rate and we call them high quality and bad. Fantastic and bad: entice fantastic and tremendous: repel terrible and terrible: repel. 20 x c isotopic symbol a typical isotopic symbol takes this form: x = detail symbol a = mass quantity (# protons # neutrons) z = atomic range (# proteins) n = # neutrons a – z = n a typical isotopic symbol takes this form: ex: the isotopic image for carbon might be: a z 12 6 x c. 19 an exception: isotopes isotopes are atoms of the equal detail which have one-of-a-kind numbers of neutrons. Recollect: the mass number tells you the wide variety of protons plus the number of neutrons. How are these carbon isotopes exceptional?.
