Write the complete ground state electron configuration of Ca.
Understand the Problem
The question is asking for the complete ground state electron configuration of the element calcium (Ca). In order to determine this, we need to understand the arrangement of electrons in the atom and how they fill the various atomic orbitals. Calcium has an atomic number of 20, meaning it has 20 electrons. The electron configuration will involve filling the orbitals following the Aufbau principle, Hund's rule, and the Pauli exclusion principle.
Answer
1s² 2s² 2p⁶ 3s² 3p⁶ 4s²
The final answer is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s².
Answer for screen readers
The final answer is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s².
More Information
Calcium (Ca), with an atomic number of 20, has its electrons arranged in a specific sequence across different atomic orbitals, describing how electrons are distributed in an atom.
Tips
A common mistake is to forget the order in which orbitals are filled or to miscalculate the total number of electrons. Rest assured each step adheres to the rules and principles governing electron configurations.
