Science 9 Test Review Questions and Answers

In full sentences, describe the similarities and differences between each pair of terms listed below. Write the page number where you find the information.
a) Physical property and chemical property
b) Ductile and malleable
c) Products and reactants
d) Element and compound
e) Atom and molecule
f) Metal and nonmetal
g) Atomic number and mass number
h) Proton and neutron
i) Period and group
j) Noble gas and alkali metal

Answers
a)Physical property and chemical property
Both changes in matter, but a chemical property results in the production of a new substance.
b)Ductile and malleable
Both involve shaping metals, but ductile refers to shaping into a wire.
c)Products and reactants
Both are required to write an equation, but reactants are the starting materials and products are the newly formed ones.
d)Element and compound
Both are pure substances, but an element contains only one kind of atom.
e)Atom and molecule
Both are particles, but an atom is indivisible in a chemical change.
f)Metal and nonmetal
Both are elements, but a metal is shiny, malleable, and conducts electricity.
g)Atomic number and mass number
Both involve counting protons, but atomic number is the number of protons only, without neutrons.
h)Proton and neutron
Both are nuclear (subatomic) particles, but a proton is positive.
i)Period and group
Both are areas of the periodic table, but a period is a row and a group is a column of the periodic table.
j)Noble gas and alkali metal
Both are elements, but noble gases are unreactive. Noble gases are in the far right column; alkali are the far left column (first group)
k)Combustion and Corrosion
Both are reactions with oxygen, but corrosion is very slow.
