We can compare his proposed atom as that of a massive billiard ball. I n the 1800’s John Dalton proposed that an atom is spherical in shape and massive. What is an atom? Has anyone seen an atom? Interesting isn’t it? Ok ok ok, but before you feel sleepy and to have a better understanding of chemical bonding, let us look at the atom first. Atoms do their bondings by either sharing its outermost electrons (covalent bonding) or by making themselves charged ( + or -) through the transfer of their outermost electrons (ionic bonding).

Similarly, atoms (though they do not have emotions) in order to become stable, they bond with each other. One being emotionally attached with friends or with family members and, as a result, one feels relax and happy. Merriam Webster defines bonding as 'the formation of relationship' also 'the attaching of a material.' In short, bonding is a form of attachment.

Bonding, can be understood, as a sort of doing something together ( enjoying together) with family members and friends. Here, the module with help you understand the world of chemical bonding. In this part of the module, the teacher is required to discuss and clarify the concepts of atomic structure and the use of the periodic table to the students. REVIEW ON ATOMIC STRUCTURE AND THE PERIODIC TABLE LESSON 9 INTERPARTICLES ATTRACTIVE FORCES LESSON 1 REVIEW ON ATOMIC STRUCTURE AND PERIODIC TABLE Strictly speaking, this document ceased to be a manuscript because of its publication and be described appropriately as draft. Another purpose is for this to be used as a review material for non-chemistry major students enrolled in general chemistry.Ĭhemical bonds is one of the topics assigned to Grade 9 Science by the Philippine Department of Education (DepEd).Īs to the title, the word 'manuscript' is used instead of 'draft' just for convenience. I will appreciate if one can point out any oversimplification that may lead to misconceptions. The purpose of publishing this through Science 2.0 is to solicit comments and suggestions prior to a formal proposal for its use in the general chemistry classes particularly, in the junior high school science. This is the first of a series of lessons about chemical bonds.
