Purpose of Strategic Intervention Material (SIM) This learning package is intended to supplement your classroom learning while working independently . The activities and exercises will widen your understanding of the different concepts you should learn.

How to use this Strategic Intervention Material (SIM)? •Keep this material neat and clean. •Thoroughly read every page. •Follow carefully all instructions indicated in every activity. •Answer all questions independently and honestly. •Write all your answers on a sheet of paper. •Be sure to compare your answers to the KEY TO CORRECTIONS only after you have answered the given tasks. •If you have questions or clarifications ask your teacher.

Do you want to know

the electron’s address?

Come on! Let’s do the succeeding tasks and activities.

GUIDE CARD

Activity 1MY ENERGY LEVEL!

Hello! Let us find how many sublevels exist in an energy level of an electron. Observe the data on the table.

ACTIVITY CARD

Activity 2HOW DO I FIT IN MY ORBITALS?

Do you find it easy to do the previous activity? Now, let us do the next exciting one!

Activity 3SPIN ME UP! SPIN ME DOWN!Wow! Great Job! Let’s do the spinning up and down of an electron as it fill the orbitals.

Activity 4MY E-CONFIGURATION!

Using your periodic table, lets write the electronic configuration of some common elements. I know that you have already an idea on how to do it. Right? Just follow the correct order on writing it.

Let me give you an example…

Silicon(14)- 1s22s22p63s23p2

Chlorine(17)-1s22s22p63s23p5I.Electron Configurations 1. Write the complete electron configuration for each atom on the blank line. LithiumFluorine __________Carbon __________ArgonSulfur __________Nickel __________RubidiumXeon

II. What elements are represented by each of the following electron configurations? a. 1s2 2s2 2p5

b. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p65s2 4d10 5p4

c. 1s2 2s2 2p6 3s2 3p6 4s2

d. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5

Since you already knew how to write the electron configuration, now its time to do it in reverse. Given the configuration, you are going to tell the element that it represents. I’ll give you an example.

1s22s22p63s2 Magnesium (Mg)Note: For you to get it easily, just count the number of electrons. The number of electrons will tell you the number of protons which is also equal to the atomic number.

Activity 5ORBITAL NOTATION

VS. E-CONFIGURATIONIsn’t it amazing??? Isn’t it surprising… In this activity, you are going to write the orbital notation from an electron configuration.

Don’t worry my friend…I will give you an example.

Ca 1s22s22p63s23p6 4s2

Mg 1s22s22p63s2

Ti 1s22s22p63s23p64s2

3d2

Remember that the total number of arrows are equal to the total number of electrons in an electron configuration. Take note with some rules in filling up the orbitals.

a. an electron can be represented by spin, one spinning up and one spinning down.

b. in filling the orbitals with electron,it should start with lowest energy level

c. an orbital in the same sublevel should be filled with one electron before sharing

d.an orbital has a maximum number of two electrons.

Good Job!

Do you understand now the concepts on the Electronic Configurations and Orbital

Notations? Well, An assesstment will be given on the next page to test the level

of your understanding. Are you ready???

BRAIN BATTLE!DIRECTIONS: Read the questions below.

Choose the best answer and write it on the space provided. Each item is worth 2 points. Good luck!

Turn to the Key Card to Check your answers.

1. How many orbitals are in the following sublevels?a) 3p sublevel = _____ d) 3d sublevel =

_____b) 2s sublevel = _____ e) 4f sublevel =

_____c) 4p sublevel = _____

2. Write the full electron configuration for each atom. a) Phosphorus = _______________________________b) Gold = _______________________________c) Iodine = _______________________________ 3. Give the symbol and names of the elements that correspond to these configurations of an atom. Where does this element belong in the period table (e.g. noble gas, metalloid, etc..) a) 1s22s22p63s1 = _________________________________b) 1s22s22p63s23p64s23d8 = _________________________________c) 1s22s22p63s23p64s23d104p4 = _________________________________
