Mr. Royer’s 3rd Quarter Review
Unit 12
Digital Vocab Flashcards that
Cover the “Periodic Table
Structure” notes
Question
The word “periodic” means…
Answer
Pattern, reoccurring, or repeating
Question
Vertical (up and down) columns are called…
Answer
Groups
Question
Horizontal (side-to-side) rows of elements are
called…
Answer
periods
Question
How many total groups comprise (make-up) the
Periodic Table of Elements?
Answer
18
Question
How many total periods comprise the P. Table?
Answer
7
Question
Why are elements stacked on top of each other
(groups) they way they are?
Answer
They demonstrate the same properties
In other words, they act/behave the same way
Question
What happens between one element to the next
as you move across any period?
Answer
The atomic number increases by one
That means the element gains one proton and
electron moving from left to right
Question
If an element gains a proton and electron as you
move across a period, what does that do to
the element’s overall size?
Answer
It gets bigger!
There are more parts so both it’s mass and
volume increase
Question
What does this red line separate on the Periodic
Table?
Answer
The metal elements from the non-metal
elements?
Question
On the P. Table what is there more of, metals or
non-metals?
Answer
Metals!
-Everything to the left of the zig-zag line
Question
What type of element exhibits the chemical
property of being “lustrous?”
Luster = shinny
Answer
Metal elements
-All metals elements can be “polished” and
become shinny
Question
What type of element exhibits the chemical
property of insulating heat and/or electricity?
Answer
Non-metals
Insulators do NOT allow heat/electricity to flow
Question
What type of elements can be rolled into wire
(ductile)?
Answer
Metal elements
Question
What type of elements break easily and are
referred to as being “brittle?”
Answer
Non-metal elements
Question
What type of elements cannot be polished
therefore looking “dull?”
Answer
Non-metal elements
Question
What type of elements can be pounded flat, also
known as being “malleable?”
Answer
Metal elements
-Gold, copper, and silver have all been used as
coins at various times in history.
Question
What type of elements allow heat and/or
electricity to pass through them easily?
Answer
Metal elements
Question
What does the atomic number represent?
Answer
The number of protons OR electrons in an
element
Helium’s Atomic number is 2. Therefore, Helium
has 2 protons and 2 electrons
Question
The atomic mass of an element is…
Answer
The amount of protons PLUS neutrons in an
element
Potassium’s atomic mass is 39. We know it has
19 protons (atomic number) so Potassium has
20 neutrons!
Question
How do you calculate the number of neutrons
an element has?
Answer
Atomic Mass – Atomic Number
The atomic number tells you exactly how many protons
there are (no calculations needed.) Since the Atomic
Mass is protons PLUS neutrons we subtract. Take a
look…
24 -12 = 12 Neutrons
Question
In a cell from the Periodic Table, how can you
tell the atomic number from atomic mass?
Answer
The Atomic Mass ALWAYS has the decimal value
AND is the larger of the two numbers
Atomic number = 12
Atomic mass = 24.31
Question
How many protons does this element have?
Answer
25 = Atomic Number = 25 Protons
-Atomic Number
Question
How many neutrons does this element have?
Answer
18
Atomic Mass – Atomic Number
35 - 17 = 18
Question
How many electrons does this element have?
Answer
13 Electrons
Atomic number = electrons
Question
These elements must be in the same (period or
group?)
and
and
Answer
Period.
There atomic numbers increase by one
Question
These elements are similar because…
and
Answer
They both are metals!
Both are to the LEFT of the zig-zag line and
So they both
-Conduct electricity/heat
-Malleable and ductile
-Are lustrous (shinny)
Question
How are these elements similar?
and
and
Answer
They are in the same group and therefore they
act the same way
-They all release their 1 valence electron (highly
reactive elements)
