The electron configuration of potassium to be predicted and the atom attaining noble gas configuration to be shown. 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.

Interpretation Introduction

Interpretation: The electron configuration of potassium to be predicted and the atom attaining noble gas configuration to be shown.

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.
