Ionic Bonds and Chlorine Stability

The video tutorial explains the ions present in sodium chloride (NaCl). It begins by identifying sodium as a metal and chlorine as a nonmetal, which form an ionic bond. The tutorial uses the periodic table to show how sodium loses an electron to become a positive ion (Na+) and chlorine gains an electron to become a negative ion (Cl-). The video concludes by summarizing the ionic structure of NaCl.

What is the chemical formula for sodium chloride?

• NaCl

• Na2Cl

• NaCl2

• ClNa

In which group of the periodic table is sodium found?

• Group 1

• Group 2

• Group 18

• Group 17

What type of bond is formed between a metal and a nonmetal?

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

What happens to electrons during the formation of an ionic bond?

• They remain unchanged

• They are transferred from metal to nonmetal

• They are transferred from nonmetal to metal

• They are shared equally

What charge does a sodium ion typically have?

• 2-

• 1-

• 2+

Why is chlorine stable after gaining an electron?

• It forms a covalent bond

• It loses energy

• It becomes a metal

• It has a full outer shell

What is the result of sodium transferring its valence electron to chlorine?
