Science Final Review 5/21
As
a
result
of
Rutherford
?
s
gold
foil
experiment
scientists
inferred
that
an
atom
?
s
charge
must
be
concentrated
in
the
of
the
atom
.
Mendeleev
created
the
first
periodic
table
by
arranging
elements
in
order
of
atomic
.
The
atomic
number
of
an
element
is
the
number

You
can
predict
an
element

based
on
its
location
on
the
periodic

Metals

The
two
most
common
alkaline
earth
metals
are
and
.
At
room
temperature
,
more
than
half
of
the
nonmetal
elements
are
.
The
elements
that
do
not
react
to
form
compounds
under
normal
conditions
are
the

Beta
radiation
consists
of
particles
that
are
identical

Measurements
of
half

life
make
radioactive
isotopes
useful
for
determining
the
ages
of

The
elements

the
same
column

The
most
reactive
metals
on
the
periodic
table

found
in

Most

A

be
pulled

In
an

the

Elements

Fluorine
,
chlorine
,
bromine

and
iodine
are
all
part
of
the
family
.
The
atomic
nuclei
of
unstable
isotopes
release
fast

moving
particles
and
energy
in
a
process
called

The
half

life
of
a
radioactive
isotope
is
the
length
of
time
needed
for
half
of
the
atoms
of
a
sample
to

Radioactive
isotopes
called
can
be
used
to
detect
some
medical
problems
.
A
piece
of
paper
will
provide
protection
from

The
series
of
electron
orbits
in

s
model

Sun
or

The
modern
periodic
table
is
organized
according
to
.
The
horizontal
rows
on
the
periodic
table
are
known
as
or
.
Nonmetals
can
be
found
on
the
side
of
the
periodic
table
.
Atoms
with
the
same
number
of
protons
and
different
numbers
of
neutrons
are
called
.
Scientific
theories
often
make
use
of
,
which
are
representations
of
an
idea
to
help
scientists
understand
what
they
cannot
directly
observe
.
Each
element
is
given
a
specific
that
usually
consists
of
one
or
two
letters
.
A
column
of
elements
on
the
periodic
table
is
called
a
or
a
because
they
have
similar
.
Elements
that
easily
transmit
electricity
and
heat
display
the
property
known
as
.
The
spontaneous
emission
of
radiation
by
an
unstable
atomic
nucleus
was
named
by
Marie
Curie
.
Mendeleev
discovered
that
periodic
patterns
appeared
when
he
arranged
the
elements
in
order
of
increasing
.
The
property
of
an
element
that
indicates
the
number
of
protons
in
its
atoms
is
the
of
that
element
.
The
chemical
reactivity
of
metals
tends
to
from
left
to
right
across
the
periodic
table
.
In
1869
,
Dmitri
Mendeleev
created
the
first
version
of
the

Most
metals
are
in
the
state
or
phase
at
room
temperature
.
The
is
the
very
small
center
of
an
atom
.
Elements
known
as
are
located
to
the
right
of
the
metalloids
on
the
periodic
table
.
At
room
temperature
,
all
the
metalloids
are
solids
,
while
many
of
the
nonmetals
are
.
Because
radioactive
isotopes
decay
at
a
predictable
rate
,
the
half
-
life
can
be
used
to
tell
how
old
a
material
is
by
the
process
of
.
Two
ways
a
proton
and
a
neutron
are
similar
are
they
have
the
same
and
are
both
located
in
the
.
Atoms
are
neutral
because
they
have
equal
numbers
of
and

The
mass
of
a

n
)
is
so
small
that
it
doesn
?
t
really
change
the
mass
of
an
atom

When
uranium

decays
into
lead

,
the
difference
between
the
mass
of
uranium
and
lead
is

while
the
difference
between
their
atomic
numbers
is

A

The
properties
of
solid
metals
can
be
explained
by
the
of
and
the
bonding
among
the
metal
atoms
.
Orderly
crystal
shapes
,
high
melting
points
,
and
electrical
conductivity
when
dissolved
in
water
are
properties
of
compounds
.
When
electrons
are
between
two
atoms
,
a
covalent
bond
is
formed
.
A
low
melting
point
is
one
property
of
compounds
.
A
nonpolar
bond
is
formed
when
two
atoms
share
electrons
.
The
overall
charge
on
an
atom
is
;
the
overall
charge
on
a
compound
is
(
overall
)
.
When
an
atom
loses
an
electron
,
it
becomes
a
(
n
)
charged
.
A
bond
is
when
two
pairs
of
electrons
are
shared
between
two
atoms
.
Aluminum
foil
is
an
example
of
a
metal
that
is
.
A
chemical
bond
formed
when
two
atoms
share
electrons
is
called
a
(
n
)
.
Electrons
involved
in
bonding
between
atoms
are
electrons
located
from
the
nucleus
in
the
and
sublevels
that
have
a
charge
.
Molecular
compounds
that
dissolve
in
water
do
not
conduct
electricity
because
no

present
.
In
the
chemical
formula
for
an
ionic
compound
,
the
name
of
the
is
written
first
.
A
mixture
made
up
of
two
or
more
elements
,
at
least
one
of
which
is
a
metal
is
called
a
(
n
)
.
Fluorine
is
a
(
n
)
molecule
because
the
valence
electrons
are
shared
equally
between
the
two
fluorine
atoms
.
Ions
that
are
made
of
more
than
one
type
of

are
examples
of

An
ionic
bond
is
the
attraction
between
charged
ions

of
a
halogen
would
need
to
react
with
one
atom
of
an
alkaline
earth
metal
to
be
stable

Calcium
phosphate
is
an
ionic
compound
with
the
chemical
formula
Ca3
(
PO4
)
2
.
The
subscript
3
tells
the
number
of
ions
present
,
the
subscript
4
tells
you
the
number
of
ions
present
,
and
the
subscript
2
tells
you
the
number
of
ions
present
.
The
subscript
of
the
phosphorus
ion
present
is
.
Because
the
electrons
in
a
molecule
of
dihydrogen
sulfide
are
more
strongly
pulled
toward
the
sulfide
atom
,
the
molecule
is
.
The
most
reactive
metals
are
the
metals
.
Solid
are
good
conductors
of
thermal
energy
and
electrical
current

Most
molecular
compounds
have
melting
points
and
boiling
points
.
A
metal

consists
of
metal
surrounded

Bonds
that
form
between
two
nonmetal
atoms
usually
are
bonds
.
When
cations
form
bonds
with
anions
,
the
charge
on
the
resulting
compound
is
.
Ionic
compounds
are
electrically

In
order
to
