Using the periodic table, determine which element has a higher electronegativity: sulfur or selenium.
Sulfur
Selenium
Both have the same electronegativity
Cannot be determined
Explain why noble gases are generally unreactive.
They have a full outer electron shell.
They have high electronegativity.
They have low ionization energy.
They are metals.
Which element is more likely to gain electrons in a chemical reaction: fluorine or lithium? Justify your answer using periodic trends.
Fluorine, because it is a nonmetal with high electronegativity.
Lithium, because it is a metal with low electronegativity.
Both are equally likely to gain electrons.
Neither, as both are stable.
How does the atomic radius change as you move from left to right across a period in the periodic table?
It increases.
It decreases.
It remains the same.
It fluctuates.
Using the periodic table, predict which element will have a higher ionization energy: nitrogen or phosphorus.
Nitrogen
Phosphorus
Both have the same ionization energy
Cannot be determined
Explain why elements in the same group of the periodic table have similar chemical properties.
They have the same number of protons.
They have the same number of valence electrons.
They have the same atomic mass.
They have the same number of neutrons.
How does the reactivity of alkali metals change as you move down the group in the periodic table?
It increases.
It decreases.
It remains the same.
It fluctuates.
Using the periodic table, predict which element will have a lower electronegativity: cesium or iodine.
Cesium
Iodine
Both have the same electronegativity
Cannot be determined
Explain why the atomic radius of elements increases as you move down a group in the periodic table.
Additional electron shells are added.
The number of protons decreases.
The number of neutrons decreases.
The number of valence electrons decreases.

The relationship of the Alien Periodic Table Activity to the actual periodic table is
that trends or patterns can be seen going across the table.
that trends or patterns can be seen going down the table.
that trends or patterns can be seen both going across and down the table.
There is actually no relationship between the 2.
Which atom is more electronegativity?
O
P
Ge
Cl
Which ion has the smaller radius?
P-3
Cl-1
S-2
all are anions in the same period so they are the same size
Which is larger:
P or P-3 ?
P because it is the neutral atom.
P-3 because it lost 3 electrons.
P-3 because it gained 3 electrons.
They are the same size since they are both P.
A sodium atom (Na) loses an electron to form a sodium ion (Na+1). Which statement is correct in regards to describing the ionic radius.
The sodium ion (Na+1) has a larger radius than the neutral sodium atom (Na).
The sodium ion (Na+1) has a smaller radius than the neutral sodium atom (Na).
The sodium ion (Na+1) and the neutral sodium atom (Na) are the same size because they are both sodium.
The sodium ion (Na+1) has twice the radius of the neutral sodium atom (Na).
Which of these isoelectronic species has the smallest radius?
Br-1
Sr2+
Rb+1
Se2-
