Lewis dot structures were invented by a guy named Lewis. Each dot in a Lewis Structure represents a valence electron, and each atom is denoted with its atomic symbol. To draw a Lewis Structure, start with the atomic symbol in the middle, then put dots around the symbol until all of the valence electrons are represented. Try to envision a box around the atom symbol, and the electrons on each side of the box. The valence electrons should be drawn around the element symbol one on each side before pairing the electrons up. The maximum number of electrons that could be on one side of a Lewis Structure is two, and the maximum number of electrons around an element symbol is eight. To figure out how many valence electrons each element has, use the Periodic Table. Remember, the number of valance electrons for Group A elements is equal to the Group A number the element is in on the Periodic Table. Explain the Lewis dot model below. What does it mean? Whats its connection to ionic bonds, octet rule, and ion formation.
Electron Affinity
When an element undergoes a chemical reaction, it either gains energy or loses energy. This gain or loss of energy is due to the phenomena that occur at atomic level. During reaction, atoms either gain electrons from other atoms or lose electrons to other atoms, and in that process, energy is produced.
P-Block Elements
Elements which are present on the right side of the periodic table are called p-block elements. In addition to the noble gases, they include the families of boron, mercury, nitrogen, oxygen and fluorine. These elements have diverse real-life implementations that we regularly experience around us.
Metals and Non-metals
The periodic table is composed of metals, semi-metals and nonmetal elements. The physical and chemical properties of metals and nonmetals differ from each other. The study of metals and nonmetals will help one to understand the appropriate application of the particular element.
