Lesson Worksheet: Types of Chemical Bonding Chemistry • 10th Grade

In this worksheet, we will practice describing the different types of chemical bonding, understanding the concept of valency, and representing chemical bonds using Lewis structures.

Q1:

The valence shell of boron is the second electron shell and contains 3 electrons. How many covalent bonds can boron form by sharing its electrons?

Q2:

Hydrogen has a single electron in its valence shell. How many covalent bonds can it form?

Q3:

The valence shell of oxygen is the second electron shell and contains 6 electrons. How many covalent bonds can oxygen form?

Q4:

The valence shell of carbon is the second electron shell and contains 4 electrons. How many covalent bonds can carbon form?

Q5:

Which of the following statements about chemical bonding is false?

  • AIn covalent bonding, electrons are shared between atoms.
  • BMolecular compounds can only contain covalent or ionic bonding, never both.
  • CIn ionic bonding, electrons are transferred between atoms, forming ions.
  • DChemical bonding involves electrostatic attractions between oppositely charged particles.
  • EIn metallic bonding, a sea of delocalized electrons is formed.

Q6:

How many electrons does an atom of strontium lose when forming the ionic compound SrI2?

Q7:

Which of the following pairs of atoms are unlikely to form a covalent bond?

  • ANeon and argon
  • BNitrogen and oxygen
  • CSulfur and chlorine
  • DCarbon and fluorine
  • EBoron and hydrogen

Q8:

Which of the following is the correct Lewis structure for a fluoride ion?

  • A
  • B
  • C
  • D
  • E

Q9:

How many atoms of bromine are usually needed to form an ionic compound with a single atom of aluminum?

Q10:

The Lewis structure for a molecular compound of potassium and sulfur is shown below. How can you tell this compound is ionically bonded?

  • AIonic compounds always contain atoms in a 2 : 1 ratio.
  • BThe atoms are sharing electrons to obtain full outer shells but have not become ions.
  • CSulfur atoms can only form ionic bonds.
  • DThe atoms have either lost or gained electrons to become ions and obtain full outer shells.
  • EThe atoms are surrounded by a sea of delocalized electrons.
