What is the key to the formation of different types of chemical bonds?

• Difference in atomic mass

• Difference in electronegativity

• Difference in atomic radius

• Difference in ionization energy

When the electronegativity difference between two atoms is more than 2, what type of bond is formed?

• Ionic bond

• Hydrogen bond

• Covalent bond

• Metallic bond

In an ionic bond, what is the charge of the sodium ion?

• Depends on the situation

• Positive

• Negative

• Neutral

What type of bond is formed when two atoms share two electrons?

• Metallic bond

• Ionic bond

• Hydrogen bond

• Covalent bond

In a polar covalent bond, which atom pulls the electron density towards itself?

• The less electronegative atom

• The more electronegative atom

• Both atoms equally

• Neither atom

If the electronegativity difference between two atoms is less than 0.5, what type of covalent bond is formed?

• Metallic bond

• Ionic bond

• Nonpolar covalent bond

• Polar covalent bond

How can you predict the type of bond that will form between two elements?

• By comparing their atomic mass

• By comparing their ionization energy

• By comparing their electronegativites

• By comparing their atomic radius

In a nonpolar covalent bond, how are the electrons shared between the atoms?

• One atom completely steals the electrons

• Neither atom shares the electrons

• Both atoms share the electrons evenly

• One atom holds the electrons more tightly

What is the main way atoms bind to one another, other than ionic and covalent bonds?

• Metallic bonding

• Dipole-dipole interactions

• Van der Waals forces

• Hydrogen bonding

What is the result of sodium and chlorine forming an ionic bond?

• Negatively charged sodium ion and positively charged chloride ion

• Neutral sodium ion and neutral chloride ion

• Positively charged sodium ion and negatively charged chloride ion

• No ions are formed
