Answer:
It is false
Step-by-step explanation:
Barium does not gain electrons to make its valences shell full. In truth, Barium loses electrons to attain a complete octet configuration of its shell.
This is because, barium is electropositive and not electronegative.
- As with most metals, barium will prefer to lose two electrons when forming bonds.
- The loss of two electrons makes it isoelectronic with the corresponding noble gas.
