3. Let’s Recap!

4. Matter is said to be made up by tiny particles. What kind of particles are these? Say something about these particles.

5. What comes to your mind when you hear the word “atom”?

6. Let’s watch a short video!

7. Let’s Play a Game!

8. “Building an Atom”

9. Building an Atom Direction: Identify the parts of the atom and paste it on its right position in the illustration.

10. Basic Structure of Atom

11. Objectives: a) describe the structure of atom; b) label the different parts of the structure of atom; and c) appreciate the role of atom in locating the elements in periodic table; At the end of the lesson, the learners should be able to;

12. Activity Time!

13. “Know Me Better”

14. “Know Me Better” Direction: Recall your knowledge. Based on the video that you watched, fill in the blanks the correct answers and answer the guided questions provided in your activity sheets.

15. An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids.

16. Atomic Particles Atoms consist of three basic particles:

37. For each of the following substances, place the symbol of the first element in its spot on the periodic table using red ink. Then, place the symbol of the second element in the substance in its spot using black ink. Direction:

38. For each of the following substances, place the symbol of the first element in its spot on the periodic table using red ink. Then, place the symbol of the second element in the substance in its spot using black ink. Direction:

39. For each of the following substances, place the symbol of the first element in its spot on the periodic table using red ink. Then, place the symbol of the second element in the substance in its spot using black ink. Direction:

40. Atoms form bonds with one another to become stable and attain the electronic configuration of the nearest noble gas through the form Covalent Bond is the coming together or sharing of electron pairs of two non-metal atoms in order to attain stability in its outer valence shell.

41. Chlorine 7 electrons on its outermost shell 17 total valence electron It needs 1 more electron to complete its octet

42. Chlorine 7 electrons on its outermost shell 17 total valence electron It needs 1 more electron to complete its octet

43. Chlorine 7 electrons on its outermost shell 17 total valence electron It needs 1 more electron to complete its octet

44. Chlorine 7 electrons on its outermost shell 17 total valence electron It needs 1 more electron to complete its octet

45. Chlorine 7 electrons on its outermost shell 17 total valence electron It needs 1 more electron to complete its octet

46. Atoms form bonds with one another to become stable and attain the electronic configuration of the nearest noble gas through the form Ionic Bond is the transfer of electrons between two or more metal and nonmetal atoms to form electrostatic attraction. Covalent Bond is the coming together or sharing of electron pairs of two non-metal atoms in order to attain stability in its outer valence shell.

47. Common Ionic Compounds

48. Common Ionic Compounds Sodium Chloride (NaCl) Table salt Hard and crystalline, white and odorless As solid, poor conductor of electricity When dissolved in water is good conductor if electricity and heat Often use for flavoring, preservative and antiseptic

49. Common Ionic Compounds Monosodium Glutamate ( C 5 H 8 NO 4 Na ) Vetsin or MSG Hard and crystalline, white and odorless, high boiling and melting point When dissolved in water, is a good conductor if electricity and heat Use for flavoring

50. Common Ionic Compounds Sodium Bicarbonate ( NaHCO 3 ) Baking Soda White crystalline and odorless High boiling and melting point When dissolved in water, is a good conductor if electricity and heat Use for ingredients of cakes and soft drinks and stain remover

51. Common Ionic Compounds Potassium Nitrate ( KNO 3 ) Matchsticks White crystalline and odorless High boiling and melting point When dissolved in water is good conductor if electricity and heat Explosive, flammable Use for fertilizers, rocket propellants, fireworks and main ingredient for match

52. Common Ionic Compounds Sodium Hypochlorite ( NaClO ) Bleach Chlorine-like and sweetish odor Unstable and explosive in higher temperatures but stable and non-explosive in lower temperatures Soluble in water, corrosive Use in oxidation of starch, disinfecting agents

53. A. Direction: Fill the tables by identifying the type of elements present in the substance. Use “M” for METAL and “NM” for NON-METALS and identify the type of chemical bond in its compounds. FORMULA 1 ST ELEMENT (M or NM) 2 ND ELEMENT (M or NM) Ionic or Covalent? CsF       PbCl 2       MnO 2       C 6 H 6       CO 2       B.
