Valency in terms of electronic theory refers to the number of bonds an atom can form to achieve a stable electron configuration. It is determined by the number of electrons an atom needs to gain, lose, or share to fill its outermost energy level and achieve a full valence shell.

What is the valency for Rubidium?
The valency for Rubidium is +1 because it readily loses one electron to achieve a stable electronic configuration.
How do you calculate the valency of an element from its electronic configuration?
To calculate the valency of an element from its electronic configuration, determine the number of electrons in the outermost shell. The valency is typically the number of electrons needed to complete the outermost shell to achieve a stable octet (eight electrons). For example, elements in group 1 have a valency of 1, while elements in group 17 have a valency of 7.
Valency of titanium?
Titanium has (max.) 4 valence electrons, possible oxidation states: +4, +3, +2, (+1, rare).
What is the valency of lithium?
The valency of lithium is 1. It has one valence electron in its outer shell.
What is the valency of Ferricyanide?
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.
What is the valency and electronic configuration of oxygen?
Electron configuration for oxygen (O) is 1s2 2s2 2p4. The valency is 2-.
What is the valency for Rubidium?
The valency for Rubidium is +1 because it readily loses one electron to achieve a stable electronic configuration.
Why some elements in the periodic table have more than one valency?
because the valency is no of electrons present in last shell and different element have different electronic configuration.
How calculate valency?
Valency is calculated in this way... 1. Find atm no of that element. 2. Write down electronic configuration. 3. Take the valence shell electron number. 4. The number of electrons to be lost are added as the valency.

How do you find out valency of mixture or compound?
To find the valency of a mixture or compound, you need to know the individual valencies of the elements involved. Valency is determined by the number of electrons an atom gains, loses, or shares to achieve a stable electron configuration. For example, in water (H2O), hydrogen has a valency of +1 and oxygen has a valency of -2, resulting in a compound with a total valency of zero.
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+.

How do you find valencies of an atom using atomic number or electronic configuration?
The number of electrons on the external level is generally equivalent to valency.

Valency of titanium?
Titanium has (max.) 4 valence electrons, possible oxidation states: +4, +3, +2, (+1, rare).
How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
What is meant by electronic theory?
Electronic theory is the theory of the behavior of the electron under various conditions including a free electron, a bound electron in either an outer or inner orbit of the atom.
