Exploring Covalent Bonding: Definitions and Examples

What type of elements participate in covalent bonding?

• Metals only

• Metals and nonmetals

• Nonmetals only

• Metalloids only

How can you identify if an element is a metal or a nonmetal using the periodic table?

• By its color on the periodic table

• By its atomic mass

• By its position relative to the staircase line

• By its atomic number

In covalent bonds, how are electrons handled?

• They are gained from the environment

• They are shared between atoms

• They are lost to the environment

• They are transferred from one atom to another

What kind of charges do atoms in covalent bonds typically have?

• No charges at all

• Full positive charges

• Full negative charges

• Partial charges or neutral

Which of the following molecules is covalent?

• NaCl

• NaBr

• Al2S3

• H2O

What does a stick represent in a covalent bond diagram?

• One electron

• A neutron

• A proton

• Two electrons

In the Cl2 molecule, how do the chlorine atoms achieve a full valence shell?

• By gaining electrons

• By transferring electrons

• By sharing electrons

• By losing electrons

What analogy is used to explain the sharing of electrons in covalent bonds?

• Two friends sharing a book

• Two friends sharing a car

• Two friends sharing a meal

• Two friends sharing a pair of shoes

In the H2O molecule, how many valence electrons does oxygen have before bonding?

• 8

• 6

• 4

• 2

What is the purpose of Lewis structures in covalent bonding?

• To show the atomic mass

• To show metallic bonds

• To show how to draw more complex molecules

• To show ionic bonds
