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.
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 ?
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
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.
