## What is condensed electron configuration?

The condensed electron configuration includes the symbol for the nearest, smaller noble gas in square brackets and then the symbols for occupied orbitals that contain valence electrons. If you add the values in the exponents of the complete electron configuration you get 39, which is correct for yttrium.

## Which of the following is the correct electron configuration for hafnium HF )?

Electron configuration of Hafnium is – [Xe] 4f14 5d2 6s2.

What is the condensed electron configuration of Mo3+?

Mo: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d4 Mo 3+: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s0 4d3 Mo is 42 on the periodic table, since the question asks for Mo3+, you have to subtract 3 electrons. Usually, it would take you at least 8 steps to determine the electron configuration.

How do you write a condensed noble gas configuration?

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium’s noble gas configuration becomes [Ne]3s1.

### What is the orbital notation for Hf?

The 4f orbital is now full of electrons. So, the remaining two electrons will enter the 5d orbital. Therefore, the hafnium(Hf) electron configuration will be 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d2 6s2.

### How many unpaired electrons are there in the ground state of Hf?

Fluorine has one unpaired electron in the ground state.

Which element has the following electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d3?

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.

What is the electron configuration for HF 72?

Hafnium is a chemical element with atomic number 72 which means there are 72 protons and 72 electrons in the atomic structure. The chemical symbol for Hafnium is Hf. Electron Configuration and Oxidation States of Hafnium Electron configuration of Hafnium is [Xe] 4f14 5d2 6s2.

## What is the electron configuration of the hafnium atom?

The electron configuration of the hafnium (Hf) atom can be done in two ways. Electron configuration through orbital (Aufbau principle) Electron configuration through orbitals follows different principles. For example Aufbau principle, Hund’s principle, Pauli’s exclusion principle.

## What are the electron configurations of elements?

List of Electron Configurations of Elements NUMBER ELEMENT ELECTRON CONFIGURATION 1 Hydrogen 1s 1 2 Helium 1s 2 3 Lithium [He]2s 1 4 Beryllium [He]2s 2

What is the Order of the electrons in the ground state?

The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers.
