Identify two ions that have the following ground-state electron configurations: (c) [Kr]5s24d10

검증된 단계별 안내
1
Identify the given electron configuration: [Kr]5s^2 4d^10.
Recognize that this configuration corresponds to a filled 4d subshell and a filled 5s subshell, which is characteristic of a transition metal ion.
Determine the element with this electron configuration in its neutral state. The configuration [Kr]5s^2 4d^10 corresponds to Cadmium (Cd) in its neutral state.
Consider the possible ions that can be formed by removing electrons from the outermost shell. For Cadmium, the common ion is Cd^2+.
Identify another ion with the same electron configuration. Silver (Ag) can lose one electron to form Ag^+ with the same electron configuration as Cd^2+.

주요 개념

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

Electron Configuration

Electron configuration describes the distribution of electrons in an atom's orbitals. It is represented using a notation that indicates the energy levels and sublevels occupied by electrons. For example, the notation [Kr]5s²4d¹⁰ indicates that the atom has a core configuration similar to krypton, with additional electrons in the 5s and 4d orbitals.

Ionic Charge

Ionic charge refers to the electrical charge that an atom or molecule acquires when it loses or gains electrons. Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons. Understanding the ionic charge is essential for identifying ions based on their electron configurations.

Transition Metals

Transition metals are elements found in the d-block of the periodic table, characterized by their ability to form variable oxidation states and colored compounds. They typically have partially filled d orbitals, which play a crucial role in their chemical behavior. The electron configuration [Kr]5s²4d¹⁰ suggests that the ions in question may be derived from transition metals, which often exhibit complex electron arrangements.

Hydrogen is an unusual element because it behaves in some ways like the alkali metal elements and in other ways like nonmetals. Its properties can be explained in part by its electron configuration and by the values for its ionization energy and electron affinity. (a) Explain why the electron affinity of hydrogen is much closer to the values for the alkali elements than for the halogens.
