Why is Chromium electron configuration Ar 4s1 3d5?

Solution : Cr has `[Ar]4s^1 3d^5` electronic configuration because half filled orbital are more stable than other orbitals.

Which element has the electronic configuration AR 4s13d10?

Why copper has (ar) 4s1 3d10 instead of (ar) 4s2 3d9 electronic configuration? – Brainly.in.

## Which element has the electron configuration AR 3d104s2?

Arsenic

The element with an electronic configuration of (Ar)4s23d104p3 ( A r ) 4 s 2 3 d 10 4 p 3 is Arsenic. This is because Ar represents 18 atoms, 2 atoms are in 4s2 4 s 2 , a0 atoms in 3d10, and 3 atoms in 4p^3. All the atoms are (18 + 2 + 10 +3) =33. The element with atomic number 33 in the periodic table is Arsenic.

### Why do we write AR in electron configuration?

When we write the configuration we’ll put all 18 electrons in orbitals around the nucleus of the Argon atom. In writing the electron configuration for Argon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Argon go in the 2s orbital.

#### What is orbital diagram of AR?

Electron configuration, Valence electrons, and Orbital diagram of Argon in tabular form

Name of atom Argon (Ar)
Number of electrons per shell [2, 8, 8]
Number of valence electrons 8
Electron configuration 1s22s22p63s23p6 or [Ne] 3s23p6
Orbital diagram Consists of five orbitals – 1s, 2s, 2p, 3s, and 3p.

Why is 3d5 more stable than 4s2?

This is so because half filled d orbitals have extra stability. So in case of Cr, one electron from the 4s orbital goes to the 3d orbital to make it half filled, and Cr attains extra stable state.

Which of the following is incorrect match Ar 3d5 4s1?

1. [Ar]3d54s1→ 4th period, 6th group. 2.

## Why electronic configuration of chromium is 3d5 4s1 instead of 3d4 4s2?

Electronic configuration of Cr is [Ar]3d5 4s1, instead of the expected [Ar]3d4 4s2. This is so because half filled d orbitals have extra stability. So in case of Cr, one electron from the 4s orbital goes to the 3d orbital to make it half filled, and Cr attains extra stable state.

### Which element corresponds to this electron configuration Ar 4s1?

The provided condensed electron structure [Ar]4s1 [ A r ] 4 s 1 represents the element Potassium.

#### Which of the following has the ground state electron configuration AR 3d104s1 group of answer choices?

1 Answer. The element is copper.

Which one of the following has the ground state electron configuration AR 3d104s1?

The ground state electron configuration for copper is Ar 3d104s1.

Which element has the electronic configuration Ar 4s13d10?

## What element is represented by the electron configuration Ar 4s23d8 Ar 4s23d8?

Answer and Explanation: This element is nickel and it has the atomic number 28. This element is arsenic and it has the atomic number 33.

### What is 1s 2s 2p 3s 3p?

1s 2s 2p 3s 3p represents the electron orbital energy levels.

#### What do you mean by 3d5?

And so we know that because we have five Electrons, this is going to be three D 1. This is three D 1, three D two etcetera. 12345. So three D five is actually manganese and we can represent the electron configuration of manganese.

How many electrons are in AR?

2,8,8Argon / Electrons per shell

Why the electron configuration of Cr is Ar 4s1 3d5 rather than Ar 4s2 3d4?

Answer: Electronic configuration of Cr is [Ar]3d5 4s1, instead of the expected [Ar]3d4 4s2. This is so because half filled d orbitals have extra stability. So in case of Cr, one electron from the 4s orbital goes to the 3d orbital to make it half filled, and Cr attains extra stable state.

## What element is Ar 3d5 4s1?

Why Chromium has [Ar] 3d5 4s1 and Copper has [Ar] 3d10 4s1? Socratic.

### Which of the following ions has electronic configuration of Ar 3d⁵?

Correct option d Co3+Explanation :The electronic configuration of the given ions is :Thus Co3+ is the ion with the desired configuration.

#### Which atom is indicated by the following electronic configuration Ar 4s¹?

Solution. The electronic configuration of the element is [Ar] 4s2 3d1= 1s2 2s2 2p6 3s2 3p6 4s23d1. Hence, the element with the electronic configuration [Ar] 4s2 3d1 is scandium (Sc).

Why is 3d5 more stable?

Due to stable electronic configuration of 3d5 & 3d10 as half filled & fully filled d-orbitals are most stable as compared to 3d4 & 3d9 . It is because of symmetrical distribution of electron density as well as greater transition energies.

Why 3d4 is not possible?

It is not true that 3d4 configuration in the ground state is not possible. It is possible but it is less stable and as every atom wants to be more stable, therefore one electron from 4s goes to 3d to obtain 3d. This doesnot mean that 3d4 is unstable, but it is less stable than half filled 3d5.
