Capitolo 6, Problema 80b
The following electron configurations represent excited states. Identify the element and write its ground-state condensed electron configuration. (b) 3Ar44s13d104p25p1
Guida verificata passo dopo passo1
Identify the given electron configuration: \([\text{Ar}]4s^13d^{10}4p^25p^1\).
Recognize that this configuration is an excited state because electrons are in higher energy levels than expected for the ground state.
Determine the total number of electrons by adding the electrons in the configuration: 18 (from Ar) + 1 (from 4s) + 10 (from 3d) + 2 (from 4p) + 1 (from 5p) = 32 electrons.
Identify the element with 32 electrons, which is Germanium (Ge).
Write the ground-state electron configuration for Germanium: \([\text{Ar}]4s^23d^{10}4p^2\).

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Electron Configuration
Electron configuration describes the distribution of electrons in an atom's orbitals. It is typically represented in a notation that indicates the energy levels and sublevels occupied by electrons. Understanding how to read and write electron configurations is essential for identifying the element and determining its ground state.

Electron Configuration Example
Excited State vs. Ground State
The ground state of an atom is its lowest energy configuration, where electrons occupy the lowest available energy levels. An excited state occurs when one or more electrons have absorbed energy and moved to higher energy levels. Recognizing the difference between these states is crucial for converting an excited state configuration back to its ground state.

Condensed Electron Configuration
Condensed electron configuration is a shorthand notation that simplifies the representation of an atom's electron arrangement by using the nearest noble gas to represent core electrons. This method makes it easier to visualize and write configurations, especially for larger elements, and is particularly useful when identifying the ground state of an element from its excited state.

If you put 120 volts of electricity through a pickle, the pickle will smoke and start glowing orange-yellow. The light is emitted because sodium ions in the pickle become excited; their return to the ground state results in light emission. b. What is the energy of 1.00 mol of these photons? (A mole of photons is called an Einstein.)
