In which Year did physics education came to Liberia? 1. electron ion molecule neutron (2) (ii) The atom of carbon is represented as: What is the mass number of this carbon atom? Carbon atoms with 7 neutrons have atomic mass of 13 (6 protons + 7 neutrons = 13). Advertisement Remove all ads. Overview of Atomic Structure. Describe and draw the structure of the atom. A positively charged sodium ion (Na +) is formed by the removal of one electron from a sodium atom. i) For Sodium atom (Na): Atomic number = 11 • Number of protons = 11 How to write the atomic structure of sodium - 1799011 Rachna11 is waiting for your help. Question Papers 10. It is as though the outer shell has vanished.The next shell in is full. When sodium reacts with non-metals (for example chlorine) it will lose its outer electron.Its outer shell will then have no electrons. Because atoms want to fill that outer electron shell, they will give away or take electrons from other atoms causing ions to form. Sodium chloride (table salt) is formed when an atom of sodium gives an electron to chlorine making the sodium a positive ion and the chlorine a negative ion. For each electron shell atom diagram, the element symbol is listed in the nucleus. Draw the Lewis electron dot structure for the following elements: a) Li b) Cr c) Rb d) Kr e) Ge 2.
