first we will make the shells as required then if the outer shell is going to have less than 8 electrons we will minus it from 8 and there comes our valancy

Valency of titanium?
Titanium has (max.) 4 valence electrons, possible oxidation states: +4, +3, +2, (+1, rare).
How do you find valency of an element?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
What is the valency of an element sodium chloride?
the valency of element sodium chloride is 1
Why do helium neon argon have a 0 valency?
Noble gases such as helium, neon, argon etc have completely filled valence orbitals, and hence have sable electronic configuration. They do not form bond with other elements. In other words, they are chemically inert and have zero valency.
How do you calculate valency of bromide?
You have to use configuration of electrons (spdf). In this case it will only go up to d. if we use the short hand configuration then bromine is 3d10 4s2 4p5. remember d goes before everything.
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.
What is the valency and electronic configuration of oxygen?
Electron configuration for oxygen (O) is 1s2 2s2 2p4. The valency is 2-.
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.
Is the electronic configuration of calcium 2882 or 2891?
The electronic configuration of Calcium is 2-8-8-2, therefore the valency of Calcium is +2.
Valency of titanium?
Titanium has (max.) 4 valence electrons, possible oxidation states: +4, +3, +2, (+1, rare).
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.
Does sodium three electrons in its valence shell yes or no?
no it has 1 electron in it's vallence.. sinc it is 1st group element and it has total 11 atoms so it's electronic configuration is (2,8,1).. so it's valency is 1
How do you find out valency of mixture or compound?
By the formula 2n2 , we can find no of electrons in shells like, if atomic no. of X is 17 so the electronic configuration is 2,8,7. so the valency is 1 in order to complete its octave.
What is the valency of the smallest element?
the smallest element is hydrogen of which its valency is one.
How do you find valency of an element?

What is the valency of an element sodium chloride?
the valency of element sodium chloride is 1
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+.
