Use the periodic table to determine the element corresponding to each electron configuration. a. [Ar] 4s²3d¹⁰4p⁶ b. [Ar] 4s²3d² c. [Kr] 5s²4d¹⁰5p²

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, the configuration [Ar] 4s² 3d² indicates that the element has the same electron configuration as argon, plus two electrons in the 4s sublevel and two in the 3d sublevel.

Periodic Table

The periodic table organizes elements based on their atomic number, electron configurations, and recurring chemical properties. Elements in the same group often exhibit similar behaviors due to their similar valence electron configurations. Understanding the layout of the periodic table is essential for identifying elements based on their electron configurations.

Transition Metals

Transition metals are elements found in groups 3 to 12 of the periodic table, characterized by the presence of d electrons. They often exhibit unique properties such as variable oxidation states and the ability to form colored compounds. The electron configuration [Ar] 4s² 3d² corresponds to titanium (Ti), a transition metal, which plays a significant role in various chemical reactions and applications.
