Chemical Bonding

Question 1

Valence electrons

Answer 1

electrons in the outer most energy level of an atom

Question 2

Octet Rule

Answer 2

all atoms bond in order to achieve noble gas configuration, which is 8 electrons in their valence energy level

Question 3

Covalent bond

Answer 3

results from sharing electrons between nonmetals. the compound formed is called a molecule

Question 4

Molecular formula

Answer 4

shows the number and types of atoms in a molecule

Question 5

Ionic bonding

Answer 5

results from the transfer of electrons between metals and nonmetals, metals lose electrons to form cat-ions , non-metals gain electrons to form anions

Question 6

monoatomic ion

Answer 6

ion with one atom , like Li+ or Br-

Question 7

Polyatomic ions

Answer 7

ions with many atoms and the charge on the ion applies to the entire group of atoms (eg, NH4+)
