Which color on this periodic table shows the F blocks?
Green
Valence electrons can be defined as the electrons on the first ring. True or false?
False
Which family of the periodic table is the least reactive?
*DOUBLE POINTS*
Noble gases
If an atom of Copper lost 3 electrons, would it become a positive or a negative ion?
Positive ion (cation)
In our modern day periodic table, the atomic number of an element is equal to what?
The number of protons and electrons in an element.
What shape is the D orbital?
Clover shape
If carbon has 4 valence electrons, what would its Lewis Dot diagram look like?
Alkali metals and alkaline earth metals are found freely in nature. True or false?
False
Ionization energy increases from _____ to _____ on the periodic table.
Left, right
Why does our periodic table have more elements on it than Mendeleev's table?
When Mendeleev was alive, many elements had not yet been found or discovered yet.
The p orbital can hold up to how many electrons?
6
What is the noble gas notation for Potassium?
[Ar] 4s1

Which family "splits" the right end of the periodic table?
Metalloids
Define electronegativity.
This is how likely an element is to bond with other elements. If it has few valence electrons, it has a high electronegativity. Many valence electrons mean the element has a low electronegativity.
Mendeleev's table was organized according to atomic weight, and elements with similar properties were put under each other. True or False?
True
In which orbital when L equals 0 does m1 also equal 0?
S orbital
Write the correct longhand electron configuration for Arsenic.
1s22s22p63s23p63d104s24p3
![]()
Which of the following are part of the halogen family?
Chlorine Nickel Rubidium Arsenic
Chlorine
Atomic radii measures the distance between the _____ and the _____ of an atom.
Nucleus/center, boundary/edge/outside
(any answers are acceptable)
List two differences between Mendeleev's periodic table and our modern day periodic table.
Mendeleev's periodic table was organized by atomic weight, whereas ours is organized by atomic number.
Mendeleev's table only had about 50-60 elements, whereas our periodic table today has 118.
There were some gaps in Mendeleev's table.
What are the quantum numbers for a 2p orbital?
*DOUBLE POINTS*
n = 2
l = 1
m1= 1
Write the correct longhand electron configuration for an Fe3+ ion.
1s22s22p63s23p63d5
Name two differences between metals and nonmetals.
Metals are shinier than nonmetals, nonmetals are poor conductors, metals are ductile but nonmetals are not, etc. (any answer is acceptable)
Why does ionic radii increase as you move down the periodic table?
Because as you move down, a new subshell/orbital is added.
Name one periodicity, or pattern, seen in our modern day periodic table.
Increasing by atomic number, ionization increases from left to right, electronegativity increases from left to right, atomic radius increases as atomic numbers get higher, etc. (any answer is acceptable)
