6.1 Ionic Bonding Notes

Stable Electron Configurations

 The _____________________ occupied energy level of an atom is filled with electrons,

◦

the atom is ______________ and not likely to _____________

◦

_______electrons in the highest energy level signifies the atom is stable

Electron Dot Diagram

 model of an atom in which each ________ represents a _______________ electron.

 The symbol in the center represents the ________________ and all the other electrons in the atom.

Stable Electron Configurations

 ________________ gases are the ______________ stable elements.

 The highest occupied energy level of a noble gas atom is completely ________________ with

______ valence electrons.

 Other elements tend to react to achieve electron configurations similar to those of noble gases.

Elements achieve stable electron configurations…

 By __________________________ of electrons from one atom to another

 This is known as __________________________________

Ionic Bonding

 Atoms will _________________ electrons from one to another in order to achieve a

__________________ electron configuration

 Occurs between a __________________ and a __________________.

Formation of Ions

 ______________= atom that has a net ________________ or ________________ electric charge



When an atom gains or losses an electron, the number of ______________ is _____ longer equal to the

number of ______________________, so the atom becomes charged.

 The charge on an ion is represented by a plus or minus sign.

◦

______________=atom that ________________________________________ electron

◦

______________=atom that ______________________ electron

 Two types of ions:

◦

Anion

◦

Cation

ANIONS

 An ion with a _______________________ charge is an ________________________.

CATIONS

 An ion with a _____________________ charge is a ________________.
