On this picture what is the atomic number?

79
What does the P in APEMAN represent?
P = Number of protons
What is the name of this model?

Bohr Model
What group is Magnesium (Mg) in?
Group 2/2A
What period is Potassium (K) in?
Period 4
On this picture what is the atomic mass rounded to the nearest hundred?

197
How do we find the neutrons using APEMAN
Mass - Atomic number = Neutrons
What 2 things are inside of the red circle? What makes up the red circle?

Protons and Neutrons
What does the group number tell you?
The number Valence Electrons on the outermost ring/shell
What does the period number tell you?
The number of rings to draw
On this picture what is the element symbol?

C
Using APEMAN how many electrons does this element have?

Electrons = 23
What do the blue circles on the rings/shells represent?

Electrons
Which pair of elements are in the same group?
Rb and Cs
Ca and Ti
Li and Be
Na and Mg
Rb and Cs (groups go up and down). They are both in group 1
Which pair of elements are in the same period?
Sr and Ta
Ta and Db
Mt and Rh
Db and Mt
Db and Mt are in the same period. Period 7
On this picture what is the element name?

Carbon
What does the A represent in APEMAN?
A = Atomic Number
What is the octet rule?
This rule means 8 electrons on the last ring/shell means the element is stable/full/happy.
Which group on the periodic table is most reactive/likely to bond with other elements?
Group 1
If we think of APEMAN, why are elements identified by their atomic number? Choose 1 answer
A. The mass of an element changes over time
B. The number of protons remains constant
C. Atoms of the same element have different numbers of neutrons
D. Elements in a group react in a similar way
A. A = P = E which means the protons remains constant and are equal to the atomic number
Where are Metalloids found on the periodic table? Which color are the Metalloids?

On the zig zag line, yellow elements
Which 3 letters all equal each other in APEMAN?
A = P = E
The atomic number = the number of protons = which also equals the number of electrons
How many protons are found in an atom of iron (Fe)?
26 Protons
Group 18 because the valence electrons on the last ring are full (octect rule)
Do elements in the same GROUP or PERIOD have the same physical characteristics?
Think of Metal, Non-Metals, and Metalloids
Elements in the same GROUP have the same physical characteristics and share similar properties
