ALEKS UPDATED TEST QUESTIONS AND
CORRECT ANSWERS
●● Atoms
Answer: Basic unit of matter which cannot be broken down and contain
mostly empty space; contains three parts: the electron, proton, and
neutron
●● Elements
Answer: A pure substance that contains only one type of atom
●● Compound
Answer: Two or more elements that are chemically bonded; includes
ionic and covalent
●● Mixture
Answer: Two or more substances that are together but not bonded
●● Pure Substance
Answer: Substance that contains only one kind of compound
●● Bose-Einstein Condensate
,Answer: The state of matter with the lowest energy; basically a very cold
solid
●● Solid
Answer: A state of matter with strong bonds
●● Liquid
Answer: A state of matter with weak bonds
●● Gas
Answer: A state of matter with no bonds
●● Plasma
Answer: The state of matter with the highest energy; it uses ionization
instead of bonds
●● Robert Boyle
Answer: First to define an element; any substance is a substance unless
it can be broken down
●● John Dalton
Answer: Used and combined previous ideas to discuss the atom;
elements are made of atoms; all atoms of an element are identical; atoms
,of different elements are different; law of constant composition; atoms
are invisible
●● Law of Constant Composition
Answer: Atoms of one element can combine with other elements to form
compounds; a given compound always has the same relative numbers
and types of atoms
●● J.J. Thomson
Answer: Discovered electrons and protons and developed the plum
pudding model of an atom
●● Electrons
Answer: The negatively charged particle in an atom; circles around the
nucleus in the electron cloud
●● Proton
Answer: The positively charged particle in an atom; located in the
nucleus; determine the element
●● Neutron
Answer: The neutral particle in an atom; it has no charge and is located
in the nucleus
, ●● Plum Pudding Model
Answer: A model of the atom that depicts a sphere of positive charge
with electrons scattered throughout
●● Ernest Rutherford
Answer: Conducted an experiment in which he shot alpha particles at
gold foil; roved there was a small, dense nucleus with a positive charge
and that protons are positive
●● Metals
Answer: Elements located on the left side of the periodic table that want
to lose electrons
●● Characteristics of Metals
Answer: - Malleable
- Ductile
- Conductive
- Lustrous
●● Malleable
Answer: The ability to be molded into shapes
●● Ductile
