Lewis dot structure of Al & Al3+

A simple notation used to represent valence electrons in an atom is called Lewis symbol. According to him, atoms achieve stable octet by gaining, loosing or sharing electrons. In electron dot structure, valence electrons are represented in the form of dots. Atoms combine with other atoms to complete their octet configuration to become stable. When electrons are shared between each other, there is a formation of covalent bond. The atomic number of Al is 13 and its electronic configuration is 2,8,3. Since there are 3valence electrons, we will show only these 3 electrons in electron dot structure Al3+ ion is formed when it looses 3 electrons. It is a cation carrying positive charge. Due to loss of electron valence shell is vacant. It means there is a presence of shell without electrons. Electron dot structure of aluminium ions can be written as (Al)3+
