WebValency of an element can be determined by knowing its electronic configuration. For Example: The atomic number of Sodium is 11. It's electronic configuration is 2,8,1. There is only 1 electron present in the valence shell of Sodium. So, it will donate its 1 electron in order to attain a stable noble configuration. WebWhile the term ‘chemical formula’ typically refers to the molecular formula of a compound (which denotes the total number of atoms of each constituent element in one molecule of the compound), the compositions of chemical compounds can be expressed in several ways, as listed in this subsection. Molecular Formula:

WebThe valency of an element determines the number of bonds that an atom can make as part of a complex. The electrons in the atom's outermost orbit are referred to as valence electrons. Valency of Carbon The atomic number of carbon is 6 with the electronic configuration of carbon represented as 1 s 2 2 s 2 2 p 2. WebThe elements of groups 1, 2, 13, 14, 15, 16, and 17 are known as the main group elements or normal elements. The elements of groups 3, 4, 5, 6, 7, 8, 9, 11 and 12 are known as the transition elements. Group 18 is called … specially selected lattice cut kettle chips
