## Has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d3?

1 Answer. Stefan V. If you are referring to a neutral atom, then Vanadium (V) has that particular electron configuration. This means that the atom you’re looking for has an atomic mass of 23, which corresponds to the atomic mass of Vanadium, a transition metal located in the fourth row, group 5 of the periodic table.

Which atom has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d2?

antimony atom
So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.

### What is the electron configuration 1s2 2s2 2p6 3s2 3p5?

The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.

How do you calculate electron configuration?

Let’s look at an example configuration for the element sodium (Na): 1s22s22p63s1

• Notice that this electron configuration is just a repeating string that goes like this: (number) (letter)(raised number)(number) (letter)(raised number)
• …and so on.
• #### How to calculate electron configuration?

– Write the electronic configuration of the atoms. Consult a diagram of electron orbital shells. – Bonding electrons are, essentially, the electrons that stick together and fall into the lowest states. – Anti-bonding electrons are the “free” or unbonded electrons that are pushed to higher orbital states. – Apply the formula,

What is the electron affinity of gold?

The electron affinity ( EA) is the energy released to add an electron to an elements in the gaseous state.

• In general successive electron affinity increase in magnitude EA1 < EA2 < EA3 and so on.
• First electron affinity increases across the period
• First electron affinity decreases down the group
• Exceptions are nitrogen,fluorine,berylium etc.
• ## What is the electron configuration of all elements?

Shells. The maximum number of electrons that can be accommodated in a shell is based on the principal quantum number (n).

• Subshells. The subshells into which electrons are distributed are based on the azimuthal quantum number (denoted by ‘l’).
• Notation. The electron configuration of an atom is written with the help of subshell labels.
• What is the electron configuration of Ca?

[Ar] 4s²Calcium / Electron configuration

### What are the valence electrons of Ca?

From the electronic configuration we know that the outermost shell of Ca is the fourth shell and the number of electrons in that shell is the valence electrons. Here there are two valence electrons in the outermost shell. So the number of valence electrons in Ca is 2.

How can we calculate valency of CA?

Thus the valency of calcium is 2 since it has 2 valence electrons. 2. If in the valence shell, the number of electrons is > 3, the atom is of a non metal. To find the valency of a non metal, subtract the number of valence electrons from 8.

#### What is the atomic number of CA?

20Calcium / Atomic number
