Honors Chemistry Unit 4 Test with comprehensive Questions and
Answers
Ionic Bond✔️✔️Force of attraction between two oppositely charged ions formed by one particle
losing electrons and another gaining electrons; formed when one atom takes an electron from
another atom--ions are the result (one positive, one negative)--they stick together because of
opposite charges; difference between electronegativities is high; formula unit; metals--low
electronegativity--lose electrons to form cations; nonmetals--high electronegativity--gain
electrons to form anions; metals-nonmetals
Covalent Bond✔️✔️Electrons are shared between atoms with relatively high electronegativity
(nonmetals); formed when both atoms have a strong attraction to the electron, so they share the
electron--neither atom has a charge; molecules; difference between electronegativities is low;
unequal sharing-polar covalent bond; equal non polar covalent bond; nonmetals-nonmetals
Metallic Bond✔️✔️Metal bonded with a metal; two or more metals atoms bonded together; occurs
when neither atom has a strong attraction to the electrons; metals have low electronegativity
values; metals bonded with other metals have "spare" electrons that end up forming the "sea of
electrons"
Polar Covalent Bond✔️✔️Bonds where the electrons are not equally shared--there is a preference
for one nucleus over the other
Semimetal✔️✔️Metallic bonds where the electrons are more tightly held; these substances will
exhibit fewer metallic properties and more covalent properties
Diatomic Molecules✔️✔️Br2, I2, N2, Cl2, H2,O2, F2; a molecule consisting of two atoms
Naming Covalent Compounds Prefixes✔️✔️1-mono
2-di
3-tri
4-tetra
