What is the ground state electron configuration for the most stable anion of sulfur?
Write the ground state configuration for the nonmetal sulfur, and predict the ion it must form to be isoelectronic with the nearest noble gas. Answer: The ground state configuration for the nonmetal sulfur is written as: 1s22s22p63s23p4. Sulfur has 16 electrons.
What's the electron configuration of a Ca 2 ion Brainly?
Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. The calcium ion (Ca 2+), however, has two electrons less. Neutral calcium’s electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2.
What is the ground state configuration?
The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state).
What is the ground state electron configuration of the chloride ion Cl − CL −?
The electronic configuration for Cl- can, therefore, be designated as 1s22s22p63s23p6. Again, the electron configuration for the chloride ion is the same as that for Ca2+ and Argon.
