What is the electron configuration for aluminum? type your answer... Copy and paste the valence into this box: type your answer... This contains how many valence electrons: type your answer... Aluminum will become a(n) choose your answer... Vwhich means it choose your answer... Which Noble gas will aluminum want to become like(use the symbol)? type your answer... What is the electron configuration for this Noble gas? type your answer.... Knowing how many valence electrons Al has, and how to tell which type of ion an element will become, adjust Al's electron configuration and place Al's ion electron configuration in the box. type your answer... What do you notice about these two configurations (choose the best answer) choose your answer... V
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.
Ionic compounds : These are formed by the transfer of electrons from one atom to another.
Atoms lose or gain electrons to attain noble gas configuration.
Number of electrons lose or gain = Valence electrons OR (8 - Valence electrons)
If an atom lose electrons it form a Cation.
If an atom gain electrons it form an anion.
