Which neutral atom is isoelectronic with each of the following ions? Ga³⁺, Zr⁴⁺, Mn⁷⁺, I⁻, Pb²⁺.

검증된 단계별 안내

Identify the atomic number of each element in the ions: Gallium (Ga), Zirconium (Zr), Manganese (Mn), Iodine (I), and Lead (Pb).

Determine the number of electrons in each ion by considering the charge. For cations (positive charge), subtract the charge from the atomic number; for anions (negative charge), add the charge to the atomic number.

Find the neutral atom that has the same number of electrons as each ion. This can be done by matching the electron count obtained in the previous step to the atomic number of a neutral atom.

Verify that the neutral atom and the ion have the same electron configuration by writing out the electron configuration for both and comparing them.

Confirm that each match is correct by ensuring that the total number of electrons in the neutral atom equals the total number of electrons in the ion, accounting for the ion's charge.

주요 개념

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

Isoelectronic Species

Isoelectronic species are atoms, ions, or molecules that have the same number of electrons, resulting in identical electron configurations. This concept is crucial for determining which neutral atom corresponds to a given ion, as it allows for the comparison of electron counts despite differences in charge.

Electron Configuration

Electron configuration describes the distribution of electrons among the various orbitals of an atom. Understanding how to write and interpret electron configurations is essential for identifying isoelectronic species, as it reveals how many electrons a neutral atom or ion possesses and how they are arranged.

Charge and Electron Count

The charge of an ion indicates the number of electrons lost or gained compared to its neutral atom. For example, a +3 charge means the ion has three fewer electrons than its neutral counterpart. This relationship is fundamental when determining which neutral atom is isoelectronic with a given ion, as it directly affects the total electron count.

Which neutral atom is isoelectronic with each of the following ions? Ga3+, Zr4+, Mn7+, I−, Pb2+.
