Worked practice questions

In which type of bonding are pairs of electrons shared between atoms?

  1. Covalent bonding
  2. Ionic bonding
  3. Metallic bonding
  4. Hydrogen bonding
Show answer and solution

Correct answer: A. Covalent bonding

1. When atoms bond, electrons are either shared or exchanged. 2. Covalent bonding is the form where pairs of electrons are shared between atoms. 3. Ionic bonding is the other route, where electrons are transferred rather than shared. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 6: Chemical bonding_

What happens to electrons when an ionic bond is formed?

  1. They are shared evenly between atoms
  2. They leave the sample completely
  3. They stay fixed on their own atom
  4. They move from one atom to another
Show answer and solution

Correct answer: D. They move from one atom to another

1. Ionic bonding happens when the two atoms differ strongly in electronegativity. 2. One or more electrons are transferred from one atom to another. 3. The atom that loses electrons becomes a positive cation and the atom that gains them becomes a negative anion. 4. The two opposite ions are then held together by electrostatic attraction. 5. Sharing electrons evenly is covalent bonding, which is the other pattern entirely. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 6: Chemical bonding_

What actually holds a piece of metal together in metallic bonding?

  1. Nuclei attract each other directly
  2. Shared pairs sit between nuclei
  3. Opposite ions attract each other
  4. Nuclei attract delocalised electrons
Show answer and solution

Correct answer: D. Nuclei attract delocalised electrons

1. In a metal the valence electrons are delocalised, so they do not stay near one nucleus. 2. The positive atomic nuclei sit in a sea of these delocalised electrons. 3. Metallic bonding is the electrostatic attraction between those positive nuclei and the delocalised electrons. 4. Because the electrons are free to move, metals conduct electricity well. 5. Because the nuclei are packed closely, metals also conduct heat well. 6. Shared pairs sitting between two nuclei describes a covalent bond, not a metallic one. 7. Opposite ions attracting each other describes an ionic bond instead. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 6: Chemical bonding_
