Interpretation: The unknown element Z and the electron does
Concept Introduction:
Formation of ions:
Atom possesses equal number of protons and electrons and remains electrically neutral. By gaining (accepting electrons) or losing (donating electrons) one or more electrons, converts the neutral atom into a charged particle called IONS.
Cation: The loss of one or more electrons by a neutral atom leaves the atom positively charged called cation.
Anion: The gain of one or more electrons by a neutral atom leaves the neutral atom negatively charged called anion.
The symbolic representation of ions:
The electrons are reside in the principal quantum number ‘n’; by losing and gaining electron, reduces and increases in the electron count in the electronic configuration of the atom; for a cation adding positive charge as a superscript to the symbol of the element and for the anion adding negative charge as superscript to the symbol of the element.
