Briefly explain why sodium readily loses an electron to form a positive ion, while chlorine readily gains an electron to form a negative ion, relating this to their electron configurations.
Briefly explain why sodium readily loses an electron to form a positive ion, while chlorine readily gains an electron to form a negative ion, relating this to their electron configurations.
Sodium has one valence electron and chlorine has seven valence electrons. Sodium loses one to achieve a full octet. Chlorine gains one to achieve a full octet.
Describe the role of electrostatic forces in the formation of an ionic bond between sodium and chlorine.
Describe the role of electrostatic forces in the formation of an ionic bond between sodium and chlorine.
The electrostatic forces are the attractive forces between the positive sodium ion and negative chloride ion.
Explain how the transfer of an electron from sodium to chlorine leads to the formation of sodium chloride (NaCl).
Explain how the transfer of an electron from sodium to chlorine leads to the formation of sodium chloride (NaCl).
A sodium atom transfers an electron to a chlorine atom to form $Na^+$ and $Cl^-$. These ions attract and form NaCl.

Study Notes
- Chemical Bonds are formed using the electric pull between positive and negative ions
- Ionic bonds are formed when electrons are transferred completely
- An example of formation of ionic bonds is Sodium Chloride
Sodium and Chlorine
- Sodium has 11 protons and 11 electrons
- Chlorine has 17 protons and 17 electrons
- Sodium has one electron in its outer valence shell
- Chlorine has seven electrons in its valence shell
- it is easier Sodium to lose just one electron than for Chlorine to gain seven electrons
