Honors Chemistry Unit 4 Test Questions And Answers
Ionic Bond ANS 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 ANS 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 ANS 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 ANS Bonds where the electrons are not equally shared--there is a preference for one
nucleus over the other



Semimetal ANS Metallic bonds where the electrons are more tightly held; these substances will exhibit fewer
metallic properties and more covalent properties



Diatomic Molecules ANS Br2, I2, N2, Cl2, H2,O2, F2; a molecule consisting of two atoms



Naming Covalent Compounds Prefixes ANS 1-mono

2-di

3-tri

4-tetra

5-penta

6-hexa

7-hepta

8-octa

9-nona

10-deca
