Section 1: Compare and Contrast Ionic and Molecular Bonding

Name:______Date:______Period:____

VALANCE ELCTRONS & STRONG ATOMS:

1) How many valence electrons do the following atoms have?

2) Write the electron configuration for the following elements:

a) Sr:______b) P:______

# of valance electrons:______# of valance electrons:______

3) How does the size of the atom affect its ability to hold onto an electron? Mighty Mouse…..

4) Cl and K are reacted. Which atom receive the electron and which atom loose the electron and why?

5) How many electrons would the following atoms loose to abide to the “octet rule”

a) Li:______b) Sr:______c) Cs:______

6) How many electrons would the following atoms gain to abide to the “octet rule”:

a) C:______b) Se:______c) Cl:______

IONIC VS COVALENT BONDING

7) Draw two atoms in ionic bonding. Be sure to show which atom takes the charge:

8) Draw two atoms in covalent bonding. Find someway to show how the charge is distributed. Be creative!

What happens in Ionic Bonding: Draw the Flourine-20 and Potassium - 50, including the nucleus’s protons and neutrons, correct energy levels, and correct number of electrons in energy levels.

Electron Configuration for F:______

Electron Configuration for K:______

1) Make the valence electrons a different color.

2) Draw an arrow at the bottom of the picture that shows the direction the valence electron is being pulled.

3) Draw another arrow from the valence electron that is going to be pulled to its new location

4) Label the side of the atom that is positive and the side that is negative.

Calculating Ionic and Molecular Bonding:

Directions: Find if the following bonds will be ionic/ polar covalent/ non-polar covalent

1) Fe and Cl:
