Chemistry 2.2: Protons, Neutrons and Electrons
Protons, neutrons, and electrons are the three main
subatomic particles found in an atom. All atoms have three
basic subatomic particles: p_______, n________, and
e________ .
Protons are located in the nucleus of an a_______.
P_______ have a positive electrical charge.
The center of the atom – the nucleus – contains the
p_______ and neutrons.
All protons are identical to each other. The p_______ of
lithium are the same as the p_______ of carbon.
p
+
P_______ are often represented with the mark of a "p+"
sign.
In every element there is the same number of p_______ as
there are electrons.
+
p
The subatomic particle represented by "p+" is the
p_______.
P_______ are always moving, called atomic vibration.
Neutrons are located in the nucleus of an atom. The center
of the atom – the nucleus – contains the p_______ and
n_______.
N_______ have no electrical charge.
0
n
N_______ are often represented with the mark of a "n0"
sign.
All neutrons are identical to each other. The n_______ of
lithium are the same as the n_______ of carbon.
0
n
The subatomic particle represented by " n0" is the
n_______.
There can be more neutrons than protons in an atom. The
copper atom has 29 _______ and 35 n_______.
Copper
N_______ are said to help hold the protons together
P_______ have a positive electrical charge. N_______
have no electrical charge.
Circling around the nucleus are tiny little particles called
electrons. There are the same number of e_______ as there
are protons in an atomic element.
E_______ have a negative charge.
E_______ have a mass that is about 1/1835 the mass of a
proton.
The e_______ orbit the nucleus in electron shells that are in
different shapes at different distances from the nucleus.
All electrons are identical to each other. The e_______ of
lithium are the same as the e_______ of carbon.
The atomic particle that carries a negative charge is the
e_______.
e
-
The subatomic particle represented by " e-" is the
e_______.
The e_______ are always found whizzing around the
nucleus in shells called orbitals.
The atomic particles that circle in "orbits" or shells around
the nucleus are e_______.
E_______ spin as they circle the nucleus billions of times
every second.
