| Question | Answer |
| Chlorine molecules (Cl₂) form single covalent bonds between chlorine atoms. Explain what the 'single covalent bond' means? Hint- Valence Electrons | A pair of electrons is shared between the Cl atoms so that each Cl atom has 8 valence electrons. A single covalent bond is formed. |
| Oxygen molecules (O₂) form double covalent bonds between oxygen atoms. Explain how this bonding occurs? | Two pairs of electrons are shared between the O atoms so that each O atom has 8 valence electrons. |
| Draw a Lewis Structure diagram for H₂, HCl and N₂ | |
| Draw a Lewis Structure diagram for H₂O, CO₂ and CH₄ | |
| What shape is made when there are 4 electron pairs around a central atom, all of which are bonding pairs? What is the bond angle? | Tetrahedral, Bond angle is 109⁰ |
| What shape is made when there are 3 electron pairs around a central atom, two of which are bonding pairs and one is a lone pair? What is the bond angle? | V-shaped or Bent, Bond angle is >120⁰ |
| What shape is made when there are 2 electron pairs around a central atom? What is the bond angle? | Linear, Bond angle is 180⁰ |
| What shape is made when there are 4 electron pairs around a central atom, 3 of which are bonding pairs, and 1 lone pair? What is the bond angle? | Trigonal Pyramid, Bond angle is at >109⁰ |
| What shape is made when there are 3 electron pairs around a central atoms, all of which are bonding pairs? What is the bond angle? | Trigonal Planar, Bond angle is at 120⁰ |
| What shape is made when there are 4 electron pairs around a central atom, 2 of which are bonding pairs and 2 of which are lone pairs? What is the bond angle? | V Shaped or Bent, Bond angle is >109⁰ |
| Draw the molecular shape of CH₄ | |
