the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron
One.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
Sodium would need to gain 7 electrons to fill its valance shell. Instead of doing that, however, sodium will lose the one valence electron it does have, leaving behind the shell below it, which is already full.

4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
A chloride ion has a larger radius than a sodium ion, because the chloride has an additional complete valence shell of electrons compared to a sodium ion, but a sodium atom has lost the only electron in this valence shell that the sodium atom ever included to form a sodium ion.
The electrons in the outermost shell is called as valence electron. These electrons are free and they are involved in bonding reactions.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
The maximum number of electrons that might be found in the valence shell is eight.
The electrons found in the outermost shell (or energy level) are known as the valence electrons.
Electrons in the outermost shell of an atom/ion are called valence electrons
yes indeed :)
Valence electrons can determine the reactivity of the atom. An atom with a full shell of valence electrons, like neon, will be less reactive than an atom with only one electron in its valence shell, like sodium.
Yes. Valence electrons are the electrons found in the outermost shell / energy level
Valence electrons
Outermost shell
Before : One electron in the valence shell After reaction w/ Cl gas: none electron in the valence shell
For group 1 elements : lithium , sodium, potassium...etc All of them have one valence electrons , however Rubidium(Rb) have two valence electrons. Therefore, Cesium have one valence electrons. :D
