A neutral atom in its ground state contains 28 electrons. this element is considered a <span>transition </span>element, and has 8 electrons in orbitals with l = 2.
Electron configuration: ₂₈X 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁸ 4s².
l is azimuthal quantum number, l = 2 describes d orbital. There is eight electrons in 3d orbital.
The ground state ion that has unpaired electrons is <u>Sc²⁺ ion</u>; option C is correct.
<h3>
What is ground state ion?</h3>
The ground state ion is the state in which all its electrons are in the lowest energy orbitals possible. You can get positive ions by removing electrons until you reach a noble gas configuration.
Ground state ion configurations are the foundation for understanding molecular bonding, properties, and structures. From the electrons in an atom to the differing orbitals and hybridization, the ground state ion configuration throws light on many different atomic properties.
For example, the electronic configuration of Sc²⁺ is 1s²2s²2p⁶3s²3p⁶ 3d¹ 4s.
In conclusion, understanding electronic configuration leads to an understanding of the periodic table.

Answer:
MgF2 - Salt
H2SO4 - Acid
Explanation:
Arrhenius Definition
Arrhenius acid is a substance that dissociates in water to form hydroxide (H+) ions.
Arrhenius base is a substance that dissociates in water to form hydroxide (OH–) ions.
H+
OH-
S2-
O2-
MgF2 - Salt as no Hydrogen
H2SO4 - Acid as converts to HSO4- and H+ upon dissociation in water.
