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
