Lesson Worksheet: Types of Chemical Bonding Chemistry
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.
Hydrogen has a single electron in its valence shell. How many covalent bonds can it form?
The valence shell of carbon is the second electron shell and contains 4 electrons. How many covalent bonds can carbon form?
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.
How many electrons does an atom of strontium lose when forming the ionic compound ?
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
How many atoms of bromine are usually needed to form an ionic compound with a single atom of aluminum?
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.
