Section 13.1

How is chemical bonding different than a chemical bond?

• Bonding is the action of forming new substances

• A bond is the interaction that holds atoms together

• Both A and B

• Neither A nor B

What energy level is filled first?

• The level closest to the nucleus

• The level farthest from the nucleus

• The level with the most amount of electrons

• The level with the least amount of electrons

How is the 1st energy level different from the 2nd energy level?

• The first energy level can only hold up to 8 electrons while the second energy level can only hold 2 electrons

• The first energy level can only hold 2 electrons while the second energy level can hold up to 8 electrons

• The first energy level maintains a positive charge while the second energy level always has a negative charge

• The first energy level always has a negative charge while the second energy level maintains a positive charge

How can the number of electrons be determined in an atom?

• From the atomic number

• From the number of protons

• Both A and B

• Neither A nor B

What are valence electrons?

• The total number of electrons in an atom

• The number of electrons in the outermost shell

• The number of electrons in the second shell

• The number of protons in the outermost shell
