Barium forms cation : Ba²⁺

<h3>Further explanation</h3>

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

ANSWER FAST, EASY POINTS
abruzzese [7]

Answer:

Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
