Barium is highly likely to form positively charged ions because it is a metal in Group 2 of the periodic table, which tends to lose two electrons to achieve a stable electron configuration. This results in the formation of Ba2+ ions when barium atoms lose two electrons.
To become more stable, calcium is likely to lose two electrons to achieve a full outer shell of electrons, forming a positive 2+ ion.

Yes, in the reaction between barium and oxygen to form an ionic compound, barium atoms will lose 2 electrons to form a Barium cation with a 2+ charge. Oxygen will gain those 2 electrons to form an oxide anion with a 2- charge.
Two electrons are donated by Barium to an oxidant (nonmetal, eg. O2) by which barium gets oxidised.Ba --> Ba2+ + 2e-This is because Ba is in group 2 of the periodic system, belonging to the 'earth alkali' metals and so it has 2 electrons (2e-) in its valency (or outer) shell (2,8,18,18,8,2). Hence Ba2+ configuration is (2,8,18,18,8,-), with an empty (-) 6th shell (the 'P' shell) like Xenon.
Two electrons.
Barium loses 2 as it is in group 2 and it's easier to lose two than to gain more than this.
Metals will LOSE electrons to become stable.

Barium oxide, as an ionic compound, involves electron transfer between barium and oxygen ions. Barium (Ba) tends to lose two electrons to become a Ba2+ cation, and oxygen (O) tends to gain two electrons to become an O2- anion, forming a stable ionic compound. This electron transfer leads to the creation of a strong ionic bond between the barium and oxygen ions in barium oxide.

Tantalum needs to lose 2 electrons to become stable. Tantalum has 73 protons, so losing 2 electrons will give it a full outer shell of 71 electrons, which is the most stable configuration for the element.
When barium and oxygen are brought together in a chemical reaction, they will likely form barium oxide (BaO). Barium will tend to lose its two valence electrons, while oxygen will tend to gain two electrons to form a stable compound.
It'll have to lose two to have a stable octet.
Calcium (Ca) typically loses 2 electrons to become more stable when bonding, as it has 2 valence electrons in its outer shell. By losing these electrons, calcium achieves a full octet, making it more stable.
