주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Quantum Numbers

Quantum numbers are numerical values that describe the unique quantum state of an electron in an atom. The four quantum numbers include the principal quantum number (n), which indicates the energy level, and the azimuthal quantum number (l), which describes the shape of the orbital. Understanding these numbers is essential for determining the electron configuration and the specific electron being removed during ionization.

Principal Quantum Number

Electron Configuration

Electron configuration refers to the distribution of electrons in an atom's orbitals. For iron (Fe), the electron configuration is [Ar] 4s² 3d⁶. When iron loses electrons to form ions, the electrons are removed from the outermost energy levels first, which is crucial for identifying which electron is lost when transitioning from Fe²⁺ to Fe³⁺.

Electron Configuration Example

Ionization

Ionization is the process of removing one or more electrons from an atom or ion, resulting in a positively charged ion. In the case of Fe²⁺ to Fe³⁺, one electron is removed from the 3d subshell. Understanding the ionization process helps in determining the specific quantum numbers of the electron that is lost during the transition between these two oxidation states.

The ionization energy of an atom can be measured by photo-electron spectroscopy, in which light of wavelength l is directed at an atom, causing an electron to be ejected. The kinetic energy of the ejected electron 1EK2 is measured by determining its velocity, v since EK = 1/2 mv2. The Ei is then calculated using the relationship that the energy of the inci-dent light equals the sum of Ei plus EK. (a) What is the ionization energy of rubidium atoms in kilo-joules per mole if light with l = 58.4 nm produces elec-trons with a velocity of 2.450 * 106m/s? (The mass of an electron is 9.109 * 10-31 kg.)
