what happens when a sodium atom loses an electron in its outer energy shell?
When a sodium atom loses an electron in its outer energy shell, or its valence shell it becomes a positively charged ion, a sodium cation with a charge of +1. It gives up the electron and undergoes potential bonding in order to acquire stability and or an octet of 8 electrons in its electron shell.
Answer : When a sodium atom loses an electrons in its outer energy then it will form a cation.
Explanation :
The sodium is metal that belongs to group 1 with atomic number 11.
The electronic configuration of sodium is, \(1s^22s^22p^63s^1\)
As we know that sodium atom loses an electron easily to acquire the stability.
The electronic configuration of sodium ion is, \(1s^22s^22p^6\)
According to the question, when a sodium atom loses an electron in its outer energy shell or valence shell then it becomes a cation which is a positively charged ion. That means sodium cation \((Na^+)\) having charge (+1).
Hence, when a sodium atom loses an electrons in its outer energy then it will form a cation.
