Question

When barium becomes positively charged, it forms a(n): (2 points)

cation
O anion
proton
O compound

Answer 1

Barium forms cation : Ba²⁺

Further explanation

Given

Barium element

Required

Ion type

Solution

Barium with the symbol Ba is an alkaline earth metal element having the atomic number 56

Electron configuration of Barium: [Xe] 6s2

If we look at this configuration, then Barium will try to achieve stability by removing 2 electrons so that the electron configuration is the same as the noble gas Xenon (Xe)

Because it removes 2 electrons, Barium has the number of protons> the number of electrons so that the charge is positive and forms a cation
