Ionic and Covalent Bonding Concepts

Why do atoms form bonds with each other?

• To become more positive.

• To increase their overall energy.

• To reduce their overall energy and find a balance.

• To become more negative.

What is the bond length between two atoms?

• The distance where the atoms are furthest apart.

• The distance where the atoms have the highest energy.

• The distance where the attractive forces are much stronger than repulsive forces.

• The distance between two nuclei where their energy is lowest.

What happens in a covalent bond?

• Atoms completely give away electrons.

• Atoms completely take electrons from each other.

• Atoms share electrons between them.

• Atoms repel each other.

What does "electronegativity" describe about an atom?

• Its size.

• Its ability to attract shared electrons.

• Its number of protons.

• Its overall charge.

What happens to electrons in a nonpolar covalent bond?

• They are completely transferred.

• They are shared unevenly.

• They are shared equally.

• They are lost by one atom.

How is an ionic bond formed?

• By sharing electrons equally.

• By sharing electrons unevenly.

• By transferring electrons from one atom to another.

• By two atoms becoming neutral.

Which of these is a property of ionic compounds?

• They are usually soft solids, liquids, or gases.

• Their solutions do not conduct electricity.

• They are often crystalline in their solid form.

• They are formed by sharing electrons.

Which of these is a property of covalent compounds?

• They are usually crystalline solids.

• Their solutions conduct electricity.

• They are formed by transferring electrons.

• They can be soft solids, liquids, or gases at room temperature.
