MCQ’s on Families of Elements on the Periodic Table

1. MCQ’s on Families of Elements on the Periodic Table Michele Mabel E. Langcauon Ramon Magsaysay (Cubao) High School

2. 1.) Which of the following chemical families contain mostly metals? a. 1, 2, and 3 b. 12, 13, and 14 c. 15, 16, and 17 d. 16, 17, and 18

3. 2.) Which of the following can be used to assess the position and reactivity of an element on the Periodic Table? a. Valence number b. Atomic number c. Atomic mass d. Period number

4. 3.) Which of the following chemical families contain metalloids? a. 1 and 2 b. 7 and 8 c. 14 and 15 d. 17 and 18

5. 4.) Which family of elements most violently reacts with halogens and water? a. Alkali metals b. Alkaline earth metals c. Transition metals d. Noble gases

6. 5.) Which family of elements reacts with halogens to form ionic compounds with the following general chemical formula: AB2? a. Alkali metals b. Alkaline earth metals c. Transition metals d. Noble

7. Correct! Congratulations. Metals are found on the left side of the ladder-like line in the periodic table and nonmetals are found on the right side of the ladder-like line. Elements that fall on the ladder-like line are considered metalloids except for aluminum.

8. Correct! Congratulations. A. ) Valence number , because it is the number of electrons in the outer shell that are used by the atom in forming chemical bonds.

9. Correct! Congratulations. C.) Families 15 and 16, because the elements in this group falls on the ladder-like line which separates the metals and the nonmetals.

10. Correct! Congratulations. A.) Alkali metals, because the elements in this group are highly reactive. Elements in this group has 1 valence electron which can be donated to family 17 elements, having 7 valence electrons to form ionic compounds.

11. Correct! Congratulations. B.) Alkaline earth metals, because these metals has 2 valence electrons and halogens has 1 valence electron.

12. Sorry! Please try again.

13. It’s the end of the test. THANK YOU!
