The reason for this is that the chemical reactivity of an atom of the element is solely determined by the number of its valence electrons, and not its inner electrons.Lewis symbols for atoms are combined to write Lewis structures for compounds or molecules with bonds between atoms. Lone electrons are represented as dots in the Lewis structure, whereas, bonds are represented as a single line in the structure. Lewis structures (also known as Lewis dot structures or electron dot structures) are diagrams that represent the valence electrons of atoms within a molecule. The Lewis theory is a theory proposed by Lewis for covalent bonding and drawing structures of the various compounds.

It is calculated by subtracting the number of valence electrons of the free atom from the number of electrons assigned to that atom in the Lewis structure. It is mined in China (worlds leading producer), Austria, Portugal and Bolivia It is an important starting reagent in the preparation of tungsten compounds. Tungsten is rather resistant to attack by acids, except for mixtures of concentrated nitric and hydrofluoric acids, and it can be attacked rapidly by alkaline oxidizing melts, such as fused mixtures of potassium nitrate and sodium hydroxide or sodium peroxide; aqueous alkalies, however, are without effect. China is the dominant producer of tungsten; in 2016 it produced over 80 percent of total tungsten mined, and it contained nearly two-thirds of the worlds reserves. The steps that must be followed while drawing a Lewis structure are listed below. The valence electron configuration for aluminum is 3s23p1. .recentcomments a{display:inline !important;padding:0 !important;margin:0 !important;} answer choices .
