Chapter 28: Problem 40

What is the ground-state electron configuration of nickel (Ni, atomic number 28 )?

Short Answer

Expert verified
Answer: The ground-state electron configuration of nickel (Ni) is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8.

Step by step solution

01

Know the atomic number and symbol for element

In this case, the atomic number (Z) of nickel (Ni) is 28, which means it has 28 electrons.
02

Apply Aufbau principle and Pauli Exclusion principle

Using the periodic table and the Aufbau principle, we fill the electron orbitals with the electrons based on their increasing order of energy levels. Remember that each orbital can contain a maximum of two electrons, in accordance with the Pauli Exclusion principle.
03

Determine the electron configuration using proper notation

Following the Aufbau principle, we fill the appropriate orbitals in order and write down the electron configuration: 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 4s^(2) 3d^(8) So, the ground-state electron configuration for nickel (Ni) is: Ni: 1s^(2) 2s^(2) 2p^(6) 3s^(2) 3p^(6) 4s^(2) 3d^(8)

Many lasers, including the helium-neon, can produce beams at more than one wavelength. Photons can stimulate emission and cause transitions between the \(20.66-\mathrm{eV}\) metastable state and several different states of lower energy. One such state is 18.38 eV above the ground state. What is the wavelength for this transition? If only these photons leave the laser to form the beam, what color is the beam?
An x-ray diffraction experiment using 16 -keV x-rays is repeated using electrons instead of \(x\) -rays. What should the kinetic energy of the electrons be in order to produce the same diffraction pattern as the x-rays (using the same crystal)?
