How do you find the electron configuration?

To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.

### How do you write configuration?

Writing Electron Configurations. When writing an electron configuration, first write the energy level (the period), then the subshell to be filled and the superscript, which is the number of electrons in that subshell. The total number of electrons is the atomic number, Z.

### Has an electron configuration ending in 3p2?

2 Answers. BRIAN M. The electron configuration 1s22s22p63s23p2 is the element Silicon.

What element is 3d3?

Also, if you look at the last number/letter combination, you can go directly to that spot on the periodic table to determine the element. Example: 1s2 2s2 2p6 3s2 3p6 4s2 3d3 (This has a total of 23 electrons which equals the atomic number of V – Vanadium.)

What is the electron configuration of K ⁺?

The full electron configuration of Potassium (K) is 1s22s22p63s23p64s1. The abbreviated form – [Ar]4s1 – means the electron configuration of Argon (Ar), plus one electron in the 4s orbital. Argon has 18 electrons.

#### What element has the valence configuration of 2p3?

Nitrogen
Element with electron configuration 1s2 2s2 2p3 is Nitrogen (N.)

#### What is 1s 2s 2p?

1s will be filled first, with the maximum of 2 electrons. • 2s will be filled next, with the maximum of 2 electrons. • 2p will be filled next, with the maximum of 6 electrons.

What does 1s 2s 2p mean?

The superscript is the number of electrons in the level. The number in front of the energy level indicates relative energy. For example, 1s is lower energy than 2s, which in turn is lower energy than 2p. The number in front of the energy level also indicates its distance from the nucleus.

What has the electron configuration 1s22s22p63s23p3?

Phosphorus has the electron configuration 1s22s22p63s23p3. Log in for more information. This answer has been confirmed as correct and helpful. All the elements in a particular group of the periodic table have the same number of Valence electrons.

## What is the electron configuration for each element?

The electron configuration of an atom of any element is the of electrons per sublevel of the energy levels of an atom in its ground state.

## What is an example of electron configuration?

Hydrogen (Z = 1): 1s 1

• Helium (Z = 2): 1s 2
• Lithium (Z = 3): 1s 2 2s 1
• Beryllium (Z = 4): 1s 2 2s 2
• Boron (Z = 5): 1s 2 2s 2 2p 1
• Carbon (Z = 6): 1s 2 2s 2 2p 2
• Nitrogen (Z = 7): 1s 2 2s 2 2p 3
• Oxygen (Z = 8): 1s 2 2s 2 2p 4
• Fluorine (Z = 9): 1s 2 2s 2 2p 5
• Neon (Z = 10): 1s 2 2s 2 2p 6
• What element has this electron configuration?

The electron configuration 1s22s22p63s23p2 is the element Silicon. The key to deciphering this is to look at the last bit of information of the electron configuration 3p2. The ‘3’ informs us that the element is in the 3rd Energy Level or row of the periodic table.
