What is an atom?
The smallest particle into which an
element can be divided and still be the
same substance. The meaning of it’s
name is “not able to be divided”.
40 Points
What is a proton?
Positively charged particle located in the
nucleus of the atom.
60 Points
What is an electron?
Negatively charged particle of the atom
surrounding the nucleus.
80 Points
What is a neutron?
Particle located in the nucleus of the
atom with no charge.
100 Points
What is the nucleus?
A dense, positively charged area of the
atom.
120 Points
What is an isotope?
An atom that has the same number of
protons but different numbers of
neutrons?
20 Points
What is they contributed to
the development of the
atomic theory?
What did Democritus, Dalton, Thomson,
Rutherford and Bohr all have in
common?
40 Points
Who is Thomson?
Scientist who created the plum pudding
model of the atom.
60 Points
What are the electrons?
The plums in the plum pudding model of
the atom.
80 Points
What is an electron?
Atomic particle with the least mass.
100 Points
What is the nucleus?
The dense positively charged part of the
atom. Most of the atom’s mass is found
here.
120 Points
What are electron clouds?
Erwin Schrodinger discovered that these
are areas where the electrons are likely
to be found.
20 Points
What is the atomic number?
The number that is the same for all
atoms of an element.
40 Points
What is an ion?
An atom that loses or gains one or more
electrons and becomes a charged
particle.
60 Points
What is the mass number?
The sum of the protons and neutrons in
the nucleus of an atom.
80 Points
What are isotopes?
Atoms of the same element that have the
same number of protons and a different
number of neutrons.
100 Points
What is the atomic mass?
The weighted average of the masses of
all the naturally occurring isotopes of an
atom.
120 Points
What is strong force?
The force that holds the protons together
in the nucleus of an atom.
20 Points
What is periodic?
Something that occurs or repeats at
regular intervals.
40 Points
What is The Periodic Table
of Elements?
The chart that lists all the elements
arranged by atomic number and set-up
in patterns that repeat
60 Points
What are metalloids?
Elements that are directly on the zig-zag
line or close to it and have properties of
both metals and nonmetals, sometimes
they are called semiconductors.
80 Points
What are alkali metals?
Group one on the periodic table with one
electron in it’s outer energy level and
very reactive. (Lithium and Sodium are
examples)
100 Points
What are alkaline-earth
metals?
Group two on the periodic table…has
two electrons in the outer energy level
and is reactive. (Beryllium and Calcium
are examples)
120 Points
What are halogens?
Second to the last group on the periodic
table…group 17…very reactive.
(Chlorine and Flourine are examples)
20 Points
What is a group or family?
A vertical column on the periodic table
40 Points
What is a period?
Name we give a horizontal row on the
periodic table
60 Points
What are the Noble Gases?
Elements in group 18…unreactive, do
not combine with other elements to form
compounds.
80 Points
What are the transition
elements?
Groups 3-12 on the periodic table…also
includes two special series of elements
on the bottom of the table.
100 Points
What are metals?
Most are solid at room temperature and
are good conductors of electricity.
120 Points
What is across each period?
The physical and chemical properties of
elements change…..
20 Points
What are metals?
This is what most of the periodic table is made
up of and they are located to the left of the zigzag line on the periodic table…they are mostly
solid at room temperature and good
conductors of heat and electricity.
40 Points
What are nonmetals?
These elements are located to the right
of the zig-zag line on the periodic
table…they contain many gases and are
poor conductors of electricity and heat.
60 Points
What are lanthanides and
actinides?
The two names of the special transition
elements series located at the bottom of
the periodic table.
80 Points
Who is Dimitri Mendeleev?
The scientist who discovered a repeating
pattern to the arrangement of the
periodic table and gave it its name.
100 Points
What is Mg?
The chemical symbol for Magnesium.
120 Points
What is 20?
The atomic number of Calcium>
20 Points
What is increasing atomic
mass?
Mendeleev arranged the elements by
their…
40 Points
What is 12?
An atom of carbon with 6 protons, 6
electrons, and 6 neutrons would have a
mass number of…
60 Points
What is nitrogen?
About 20% of the air we breathe is
oxygen…this element makes up the
most part of the air we breathe….almost
80%.
80 Points
What is a radioactive
isotope?
An unstable atom with a nucleus that will
change over time.
100 Points
What is 92?
The total number of naturally occurring
elements there are in the world?

What is periodic law?
States that the properties of elements
change periodically with the elements’
atomic numbers.
