The given pictures to be predicted as Cl − and Cl − . Concept Introduction: Atomic radii: The distance between the nucleus and the outermost electron of the atom. Ionic radii: The distance between the nucleus and the outermost electron of the ion. 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 in superscript to the symbol of the element and for the anion adding negative charge in superscript to the symbol of the element.

Interpretation Introduction

Interpretation:

The given pictures to be predicted as Cl− and Cl−.

Concept Introduction:

Atomic radii: The distance between the nucleus and the outermost electron of the atom.

Ionic radii: The distance between the nucleus and the outermost electron of the ion.

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 in superscript to the symbol of the element and for the anion adding negative charge in superscript to the symbol of the element.
