Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 Short-hand version: [Ar] 4s^2 Note: The "^" symbol means the the following number is in the form of a superscript.
1s2 2s2 2p63s23p64s2
Calcium (Ca) has 20 electrons and its electron configuration is [Ar] 4s². To attain a noble gas electron configuration, calcium needs to lose two electrons to achieve the stable electron configuration of argon ([Ar] 4s² 3d¹⁰).
The correct full electron configuration for neon (Ne) is 1s2 2s2 2p6.
No, the electron configuration is incorrect. The correct electron configuration for an element with 52 electrons would be Kr 5s2 4d10 5p6.
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).

Calcium loses two electrons to obtain a noble-gas electron configuration.
No, the electron configuration is incorrect. The correct electron configuration for an element with 52 electrons would be Kr 5s2 4d10 5p6.
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
The element with this electron configuration is calcium (Ca), which has 20 electrons.
The electron configuration provided seems to be incorrect. The correct electron configuration for an element is based on the Aufbau principle, which governs the way electrons fill energy levels and sublevels. Double-check the electron configuration using the correct order of filling for orbitals.
