Write the ground state electron configuration for calcium (Ca).
Understand the Problem
The question is asking for the electron configuration of calcium in its ground state, which involves determining how electrons are distributed among the atomic orbitals. Calcium has 20 electrons, and we need to arrange them according to the Aufbau principle, filling the lowest energy levels first.
Answer
1s2 2s2 2p6 3s2 3p6 4s2
The ground state electron configuration for calcium (Ca) is 1s2 2s2 2p6 3s2 3p6 4s2.
Answer for screen readers
The ground state electron configuration for calcium (Ca) is 1s2 2s2 2p6 3s2 3p6 4s2.
More Information
Calcium has an atomic number of 20, indicating it has 20 electrons in the ground state.
Tips
A common mistake is to incorrectly fill the orbitals out of order. Ensure you follow the Aufbau principle.
