3What is the name of an ionic compound that consists of lithium ions and iodide ions? [blank_start]_________[blank_end]
- Alithium iodide
4Ionic compounds are named for their positive metal ion first, then their negative [blank_start]______[blank_end] ion.
- Anonmetal
5How are ionic compounds named?
- Apositive ion comes first in the compound name
- Bnegative ion comes first in the compound name
- Cion in the higher numbered period comes first in the compound name
- Dtwo of the above
6All compounds form when atoms of different [blank_start]_________[blank_end] share or transfer electrons
- Aelements
7Compounds in which electrons are transferred from one atom to another are called _________?
- Achemical compounds
- Bionic bonds
- Ccovalent compounds
- Dionic compounds
8Because the positive and negative charges cancel out, an ionic compound is [blank_start]_______[blank_end] in charge.
- Aneutral
9 A [blank_start]_________[blank_end] consists of many alternating positive and negative ions bonded together in a matrix.
- Acrystal
10Many compounds form molecules, but ionic compounds form what?
- Aionic compounds form compounds as well
- Bcrystals
- Cionic bonds
- Dionic molecules
11Ionic compounds generally form between:
- Anonmetals and nonmetals
- Btransition metals and nonmetals
- Cnonmetals and metals
- Dhalogens and metals
12True or False: Ionic compounds are named for their positive and negative ions. The name of the positive ion always comes first, followed by the name of the negative ion.
- AVerdadero
- BFalso
13The crystal structure of ionic compounds is strong and[blank_start]_____[blank_end].
- Arigid
14True or False: Solid ionic compounds are poor conductors of electricity.
- AVerdadero
- BFalso
15Dissolved ionic compounds are called ________.
- Aions
- Batoms
- Celectrolytes
- Dhalgoens
16Why are solid ionic compounds poor conductors of electricity?
- AThe strong bonds between their positively charged ions lock them into place in the crystal. Therefore, the charged particles can move freely and carry electric current,
- BThere are no bonds in their crystals to create and carry electrical currents.
- CThe strong bonds between their oppositely charged ions lock them into place in the crystal. Therefore, the charged particles cannot move freely and carry electric current,
17The rigid crystals of ionic compounds are ______?
- Asoft
- Bmalleable
- Crough
- Dbrittle
18Are the rigid crystals of ionic compounds more or less likely to shatter when struck?
- Aless likely
- Bmore likely
- CRigid crystals cannot be broken
19True or False: The human body needs several ions for good health.
- AVerdadero
- BFalso
20Ionic compounds consist of oppositely charged ions that are held together by [blank_start]________[blank_end].
- Aionic bonds
21Ionic compounds exist as [blank_start]_________[blank_end] rather than molecules.
- Acrystals
22A crystal consists of many _______________ ions bonded together in a matrix.
- Aalternating positive and negative
- Balternating neutral
- Calternating negative
23True or False: Ionic compounds are good conductors of electricity but only when dissolved in water.
- AVerdadero
- BFalso
