What does the electron in the outer most level determine?
It is generally called the valence electron as it determines the valency of electrons.
What is the valency of barium?
As Barium's atomic number is 56 and as it has 2 electrons in its outer shell (this is also due to the fact that it is in Group 2) its valency is 2. It loses 2 electrons to attain the electronic configuration of Xenon whose atomic number is 54, so it is electropositive and is a metal.Therefore its valency is 2+.

Which element has highest valency?
The element with the highest valency is fluorine, which has a valency of 7. This means that fluorine can form compounds by gaining one electron to complete its outer shell and reach a stable electron configuration.
What is the formula for valency?
The valency of an element is determined by the number of electrons it gains, loses, or shares to achieve a stable electron configuration. It is typically the same as the number of electrons an element needs to gain or lose to achieve a full outer shell (octet). For example, elements in Group 1 have a valency of +1 because they lose one electron to achieve stability, while elements in Group 17 have a valency of -1 because they gain one electron to achieve stability.
What is the valency of 31st element?
The 31st element is Gallium (Ga) with an atomic number of 31. Gallium commonly exhibits a valency of +3 in chemical compounds due to the three valence electrons in its outer shell.
What is the valency of neon and argon?
valency of argon is 0 that the shell is completely filled
What is the valancy of brelium?
The valency of beryllium is +2. Beryllium typically forms compounds in which it loses its two outer electrons to achieve a stable electron configuration.
What is the valency of ne?
Neon (Ne) is a noble gas and has a valency of 0. It is stable with a full outer shell of electrons.
What is the valency of Bromide?
-1 valency
How do you find valency?
The valency of an element measures its ability to combine with other elements. This valency is determined by the number of electrons in the outer shell of each atom of an element.
If an atom Y contains 6 electrons in the outer shell what will be its valency?
It needs two more electrons to complete octet and hence its valency will be two if it is non metallic.
What is the valency of helium?
Helium has a valency of 0 because it has a full outer shell with 2 electrons, making it stable and unreactive.
What is the valency of boron?
Boron typically has a valency of 3 because it has 3 valence electrons in its outer shell. This means it tends to form compounds where it can share or donate those 3 electrons to achieve a stable electron configuration.
What is the most important factor in an elements place in the periodic table?
Its elemental weight
How many valance electrons are in magnesium?
Magnesium has 2 electrons in its outer most shell and these 2 are the valency electrons.
Why does neon have zero valency?
Neon has a complete outer electron shell with 8 electrons, making it stable and unreactive. Since it does not need to gain, lose, or share electrons to achieve a stable electron configuration, it is considered to have zero valency.
Why is the valency of chlorine one?
Chlorine has a valency of one because it has seven valence electrons in its outer shell. By gaining one electron, chlorine can achieve a stable electron configuration similar to that of a noble gas, specifically argon, which has a full outer shell with eight electrons.
