All neutral atoms contain a specific amount of electrons. The amount of total electrons in a neutral atom will always be equal to its number of protons (also known as the atomic number). While all electrons play a role, none of the electrons play a bigger role than the valence electrons....

Valence electrons are the electrons in the outermost electron shell of an atom. The number of electrons in an atom's outermost valence shell governs its bonding behavior. That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. Within...

Valence electrons in an atom are the electrons (normally in the outermost shell) that can be shared or transferred to form bonds. In fact, in an atom, the inner electrons (beyond the outermost shell) are unusable and do not directly determine the chemistry of the elements....
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
Valence electrons:Valence electrons (VE) are generally negatively charged particles. These electrons are arranged in different orbits or shells. They are important for the formation of chemical bonds and for the interaction between atoms. Valence electrons are also called outer-shell electrons. Valence...
Neutral Atoms: A neutral atom is one that has an equal number of protons and electrons. The positive charge of the protons and the negative charge of the electrons will cancel each other out. In the case of argon, it has 18 protons and thus will be neutral if it has 18 electrons ...
