What tripositive ion has the electron configuration 3Kr4 4d3?

Key Concepts

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, '3Kr4 4d3' indicates that the ion has electrons filling up to the 4d subshell, which is crucial for determining the ion's chemical properties.

Tripositive Ion

A tripositive ion, or a cation with a +3 charge, is formed when an atom loses three electrons. This process affects the electron configuration and can significantly alter the atom's reactivity and bonding characteristics. Understanding how to derive the correct electron configuration for a tripositive ion is essential for identifying the element.

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 complex ions. The electron configuration of transition metals often involves the d orbitals, which play a key role in their chemical behavior. Recognizing the properties of transition metals helps in identifying the specific tripositive ion in question.
