Respuesta :
Since barium is in group 2. Atoms in group 2 lose 2 electrons to form ions with a + 2 charge. The resulting ion barium forms is Ba^+2.
Answer: Barium will form ion having a charge of +2
Explanation:
An ion is formed when an atom looses or gains electrons.
- When an atom looses electrons, it leads to the formation of positive ion known as cation.
- When an atom gains electrons, it leads to the formation of negative ion known as anion.
We are given:
Barium is the 56th element of the periodic table having electronic configuration of [tex][Xe]6s^2[/tex]
This element will loose 2 electrons to form [tex]Ba^{2+}[/tex] ion
Hence, barium will form ion having a charge of +2
