First let us identify its ground state configuration.
[Xe]6s1
The inner electron is the number of electron 54 (in Xe).
Inner electrons: 54
The valence electron and outer electron in this one is the same because it is in 6s. 1.
Outer electrons: 1
Valence electrons: 1
<h3>What is valence electron?</h3>
A valence electron is an electron that is part of an atom's outer shell in chemistry and physics.
If the outer shell is open, the valence electron can take part in the formation of a chemical bond.
Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
The chemical properties of an element, such as its valence—whether it can connect with other elements and, if so, how quickly and with how many—may be affected by the existence of valence electrons.
In this approach, the electrical arrangement of an element greatly influences its reactivity.
<h3>What is electron?</h3>
The elementary charge, commonly known as the electric charge, has an electric charge of 1.602176634 coulombs, which is used as a standard unit of charge for subatomic particles.
The electron charge is identical to the proton charge, within the limits of experimental precision, but with the opposite sign.
Because the Himalayan mountains seperate India from the rest of Asia, it is a subcontinent(subcontinent is a distinguishable part of a continent) and India has many geographical features of a continent, but it is not big enough to be one...which is another reason why its called subcontinent.
A balanced chemical equation is needed ,because it helps to determine the mole ratio of acid and base.
The mole ratio ensures that the number of moles of H+ provided by the acid is equal to number of moles of OH- ion provided by the base, For neutralization to occur, this must be the case.
It has to be noted that sodium is an element which belongs in the first column of the periodic table. This means that it has a valence electron of 1 which further means that it is capable of donating one of its electron to another element during reaction. This is exactly the explanation as to why it becomes charged +1 after the reaction.
