Chemical Bonding Quiz

What are chemical bonds?

• Physical barriers between atoms

• Mutual electrical attractions between nuclei and valence electrons of different atoms

• Random connections between atoms

• Strong forces that repel atoms from each other

What is the natural tendency of atoms in terms of potential energy?

• To maintain a constant potential energy

• To lower their potential energy by forming chemical bonds

• To have no potential energy

• To increase their potential energy by staying alone

What is the main difference between ionic and covalent bonding?

• Ionic bonding involves electron sharing, while covalent bonding involves electron transfer

• Ionic bonding only occurs in metals, while covalent bonding only occurs in non-metals

• Ionic bonding is weaker than covalent bonding

• Ionic bonding involves electron transfer, while covalent bonding involves electron sharing

How do chemists determine if a bond is ionic or covalent?

• By observing the physical state of the compound

• By looking at the color of the atoms involved

• By calculating the difference in electronegativity between the atoms

• By measuring the bond length

What is a polar covalent bond?

• A bond where electrons are not shared at all

• A bond where electrons are completely transferred from one atom to another

• A bond where electrons are shared equally between two atoms

• A bond where electrons are shared but tend to favor one atom over the other

In an ionic bond, what happens to the electrons?

• They are completely transferred from one atom to another

• They are repelled by the nuclei

• They are lost in space

• They are shared equally between the atoms

What is the role of valence electrons in chemical bonding?

• They are not involved in bonding

• They determine the color of the compound

• They are the electrons in the outermost energy level and are involved in bonding

• They are responsible for the physical state of the compound

How do metals and non-metals behave in terms of electron transfer?

• Metals tend to gain electrons, while non-metals tend to lose electrons

• Metals and non-metals always share electrons

• Metals and non-metals do not participate in electron transfer

• Metals tend to lose electrons, while non-metals tend to gain electrons

What is the purpose of chemical bonds in atoms?

• To make atoms unstable

• To store potential energy and make atoms more stable

• To repel other atoms

• To increase potential energy

How do atoms bond in covalent bonding?

• By losing all their electrons

• By repelling each other

• By sharing a pair of electrons

• By completely transferring electrons
