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 electronic configration in O2?
The electronic configuration of oxygen is: [He]2s2.2p4.
Does oxygen exihibit variable valency?
it does. for example in H2O oxygen has a valency 2 while in hydrogen peroxide H2O2 oxygen exhibits valency 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+.

What noble gas does oxygen want to be like?
Oxygen receives 2 electrons, so it has the electronic configuration like neon.
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 get the electronic configuration of oxygen?
The electron configuration of oxygen is 1s22s22p4.

How is the valency of oxygen two?
The valency of oxygen is two because oxygen typically forms covalent bonds by sharing two electrons with other atoms. This allows oxygen to achieve a stable octet configuration, which is energetically favorable.
What is electronic configration in O2?
The electronic configuration of oxygen is: [He]2s2.2p4.
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 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.
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 number of outer electrons is in oxygen?
6. Oxygen has an electronic configuration of [He]2s22p4
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.
Why the valency of oxygen is 2?
Oxygen has 6 valence electrons in its outer shell, which allows it to form two bonds with other atoms to achieve a stable octet configuration. This results in an oxidation state of -2 for oxygen in most compounds, making its valency 2.
Valency of titanium?
Titanium has (max.) 4 valence electrons, possible oxidation states: +4, +3, +2, (+1, rare).
