The location of an electron within any specified element's atom is governed by using certain numbers. These are basically called quantum numbers. All the electrons are arranged in a regular manner in various orbitals.Answer and Explanation: ...

To determine the number of valence electrons in the atom of an element A with atomic number 20 and to identify its valence shell, follow these steps:Step 1: Write the Electronic Configuration The atomic number of element A is 2
A valence electron is an electron that 'lives' in the last electron shell (or valence shell) of an atom. The atom will have one or more electron shells based on how many electrons the atom has. The very last shell that the atom has holds the valence electrons. The number of valence ...
The rule is inapplicable to the transition and inner transition elements (we’ll get to that reason in a minute). For instance, Sodium (Na) resides in Period 3, Group 1, which implies that it has 3 shells and a single electron in its valence shell. ...
Valency is the count of an atom's electrons that participate in bond formation. Chlorine has a valency of one, as it needs one more electron to achieve a stable electron configuration. 11 Valence It encompasses the types of chemical bonds atoms can form, like ionic or covalent. Sodium (Na...
