All neutral atoms have same number of electrons as that of protons known as the
The loss or gain of electron results in the formation of ions. The loss of electron forms cation results in positive charge on parent atom whereas the gain of electron forms anion results in negative charge on parent atom.
Interpretation:
The number of electrons present in Br- ion should be determined.
Concept Introduction:
All neutral atoms have same number of electrons as that of protons known as the atomic number of the element. Every element has a unique atomic number through which it is identified. The number of protons remain intact.
The loss or gain of electron results in the formation of ions. The loss of electron forms cation results in positive charge on parent atom whereas the gain of electron forms anion results in negative charge on parent atom.
