What is electronic configration in O2?
The electronic configuration of oxygen is: [He]2s2.2p4.
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 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+.

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 noble gas does oxygen want to be like?
Oxygen receives 2 electrons, so it has the electronic configuration like neon.
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.
How do you get the electronic configuration of oxygen?
The electron configuration of oxygen is 1s22s22p4.
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 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.
Valency of titanium?
Titanium has (max.) 4 valence electrons, possible oxidation states: +4, +3, +2, (+1, rare).
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.
What is the valency of oxygen?
Oxygen has 2 as its valency.
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 value of oxide ion and phosphate ion?
Oxide - O2- electronic configuration of oxygen atom: 1s2, 2s2 2p4. electronic configuration of oxygen ion: 1s2, 2s2 2p6. phosphate - PO43-
Why are two molecules of oxygen more stable than three molecules of oxygen?
This is because in nitrogen the 2p subshells are filled by 3 electrons which is half filled electronic configuration. But oxygen has to lose an electron to attain the half filled electronic electronic configuration. Hence nitrogen is more stable than oxygen.
