Chapter 6-7 Chemistry Test
bonding - ✔✔ correct answer chemical combination of atoms
compounds - ✔✔ correct answer result of chemical combinations of atoms
octet - ✔✔ correct answer having eight valence electrons that is the most stable
Why do atoms bond? - ✔✔ correct answer atoms are trying to achieve an octet
How can an octet be achieved? - ✔✔ correct answer 1. gaining/losing electrons
2. sharing electrons
Octet Rule - ✔✔ correct answer atoms tend to lose, gain or share valence electrons with other atoms
in order to get eight electrons in their outermost energy level
Two Types of Bonds - ✔✔ correct answer 1. Covalent Bonds
2. Ionic Bonds
Covalent Bonds - ✔✔ correct answer Result from the sharing of an electron pair between the nuclei
of two atoms
Ionic Bonds - ✔✔ correct answer Result from atoms transferring electrons (one atom gives, one
atom takes)
Ionic Bonding - ✔✔ correct answer Usually occurs between metals and non-metals
Covalent Bonding - ✔✔ correct answer Usually occurs between non-metals and other
non-metals/semi-metals
covalent bond - ✔✔ correct answer a bond in which one or more pair of valence electrons are
shared between atoms
molecule - ✔✔ correct answer the result of covalently bonded atoms
, Chapter 6-7 Chemistry Test
diatomic molecule - ✔✔ correct answer molecule consisting of two of the same atoms
single bond - ✔✔ correct answer one pair of electrons shared between atoms
double bond - ✔✔ correct answer two pair of electrons shared between atoms
triple bond - ✔✔ correct answer three pair of electrons shared between atoms
structural formula - ✔✔ correct answer a chemical formula showing the linkage of the atoms in a
molecule diagrammatically using the chemical symbol and lines
resonance structures - ✔✔ correct answer structural formulas for molecules that vary in the
arrangement of the electrons
polyatomic ion - ✔✔ correct answer a group of covalently bonded atoms that loses or gains
electrons
OH^- - ✔✔ correct answer Hydroxide
NO3^- - ✔✔ correct answer Nitrate
CH3COO^- - ✔✔ correct answer Acetate
HCO3^- - ✔✔ correct answer Bicarbonate
