Ganesha Education University

I. Identity

Subject                         : Chemistry

Class/Semester             : X/1

Time Allocation            : 45 minutes

Standard Competence: 1. Understanding atomic structure, unsure periodicity properties, and chemical bonding.

II. Basic Competence

1.2 Compare ionic bond making process, covalent bond, coordination covalent bond and metallic bond then the relationships with physical properties of compound that form.

III. Indicator

• Explain the forming process of ionic bonding and the example compounds.

IV. Matter

  1. Pre requisite concepts/conceptions
  • Ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
  • Electron configuration is the arrangement of electrons of an atom, a molecule, or other physical structure.
  • Positive and negative ion forming.
  • Ionic bonding form from electrostatic interaction from Positive with negative ion forming.

  1. Matter Description

An ionic bond is a type of chemical bond that involves a metal and a nonmetal ion (or polyatomic ions such as ammonium) through electrostatic attraction. In short, it is a bond formed by the attraction between two oppositely charged ions.

The metal donates one or more electrons, forming a positively charged ion or cation with a stable electron configuration. These electrons then enter the non metal, causing it to form a negatively charged ion or anion which also has a stable electron configuration. The electrostatic attraction between the oppositely charged ions causes them to come together and form a bond.

For example, common table salt is sodium chloride. When sodium (Na) and chlorine (Cl) are combined, the sodium atoms each lose an electron, forming a cation (Na+), and the chlorine atoms each gain an electron to form an anion (Cl). These ions are then attracted to each other in a 1:1 ratio to form sodium chloride (NaCl).

Na + Cl → Na+ + Cl → NaCl

Sodium and chlorine bonding ionically to form sodium chloride. Sodium loses its outer electron to give it a noble gas electron configuration, and this electron enters the chlorine atom exothermically. The oppositely charged ions are then attracted to each other, and their bonding releases energy. The net transfer of energy is that energy leaves the atoms, so the reaction is able to take place.

V. Learning and Teaching Strategies

  • Approach         : deductive
  • Method            : lecture/talk
  • Technique         : lecture the matter with example.
