Unit 6: Notes 1 & 2 Video Lecture Honors Chem

What is the main difference between ionic and covalent bonds?

• Both ionic and covalent bonds involve sharing electrons.

• Ionic bonds only occur between nonmetals.

• Ionic bonds transfer electrons, while covalent bonds share them.

• Ionic bonds involve sharing electrons, while covalent bonds transfer them.

What is the main reason atoms form bonds?

• To become unstable

• To mimic noble gases and achieve stability

• To lose all their electrons

• To increase their size

Which of the following is a property of covalent compounds?

• They are usually gases or liquids at room temperature.

• They are made of metals and nonmetals.

• They have high melting points.

• They conduct electricity well.

What does it mean when an element is diatomic?

• It always exists as a pair of atoms when pure.

• It exists as a single atom in nature.

• It cannot form bonds with other elements.

• It forms bonds with metals only.

Which of the following is a property of covalent compounds?

• Good electrical conductivity

• High melting points

• Low melting points and poor electrical conductivity

What happens to bond length as the number of shared electrons increases?

• It becomes unpredictable

• It increases

• It decreases
