# What is valence shell electron configuration?

## What is valence shell electron configuration?

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.

## How do you write valence electron configuration?

Write the valence electron configuration of each element by first indicating the filled inner shells using the symbol for the nearest preceding noble gas and then listing the principal quantum number of its valence shell, its valence orbitals, and the number of valence electrons in each orbital as superscripts.

What is the valence shell electron configuration of Group 14 elements?

The elements of group 14 are Carbon ( C ), Silicon (Si), Germanium (Ge), Tin (Sn) and Lead (Pb). The general outer electronic configuration of group 14 elements is ns2np2.

### How do you calculate valence shell?

For neutral atoms, the number of valence electrons is equal to the atom’s main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.

How do you calculate the Valency of an element from its electronic configuration?

Answer: The valency of an element is determined by the number of valence electrons present in the outermost shell of its atom. The number of electrons lost or gained (or shared) by one atom of an element to achieve the nearest inert gas electron configuration, gives us the valency of the element.
