Answer: The ion formed is [tex]Z^{2+}[/tex]
Explanation:
An ion is formed when an atom looses or gains electron.
- When an atom looses electrons, it will form a positive ion known as cation.
- When an atom gains electrons, it will form a negative ion known as anion.
We are given:
Atomic number of element Z = 20
The electronic configuration of neutral atom = [tex]1s^22s^22p^63s^23p^64s^2[/tex]
The electronic configuration of the ion = [tex]1s^22s^22p^63s^23p^6[/tex]
As, the given element is loosing 2 electrons. So, it will form a positive ion having charge of +2.
Hence, the ion formed is [tex]Z^{2+}[/tex]
