Answers
1
This trend is accurate for all but
First Ionization Energy
Atomic Radius
Electronegativity
2
The outermost energy level in an atom is referred to as the
valence shell
outer energy level
sub-shell
electron orbital
3
Ionization Energy increases across a period because of
increased amount of negative charge
increased electron shielding
increased nuclear charge (number of protons)
increased number of valence electrons
4
The tendency for an atom to attract electrons in a bond towards itself (pull on electrons from nucleus)
Bad Sharing
Electron Affinity
Metallic Character
Electronegativity
5
Which of the following has the largest atomic radius?
Li
Rb
H
Cs
6
Which atom has the largest radius?
Kr
K
Br
Ca
7
Which element typically forms +1 cations
Ga
Ca
As
K
8
When two different ions or elements have the same number of electrons they are called
Isoelectronic
Ions
There is no specific term
Isotopes
9
Which atom has the least electronegativity?
Si
Mg
Na
Al
10
Ionization Energy
Increases across a period and decreases down a group
Increases across a period (L->R) and increases down a group
Decreases across a period and decreases down a group
Decreases across a period and increases down a group
11
Electronegativity increases up a group because
the increased number of valence electrons
the increased number of protons
elements at the top are more greedy
the lesser amount of energy levels and electron shielding
12
Which of the following trends do energy levels and/or electron shielding impact? Be careful!
Atomic Radius
Electronegativity
Ionization Energy
All of the Above
13
Which element typically forms -1 anions?
C
F
N
O
14
Fluorine has the greatest...
Electronegativity
Metallic Character
Atomic Radius
Electron Affinity
15
Atomic Radius increases going down a group because
the increased number of energy levels or shells
the increased number of protons
the increased number of neutrons decreases the charge
16
All of our trends changed going down a group because of
adding more energy levels (electron shielding)
the increase in the number of protons holds electrons closer
the elements are more metallic like
17
A Group or Family on the periodic table is in what orientation?
A Diagonal (don't pick this)
Horizontal
Vertical
18
Which atom has 7 valence electrons and is a halogen?
O
Be
F
Li
19
The alkaline earth metals are in what group?
Group 1
Group 18
Group 2
Group 17
20
List the correct ionic radius size (increasing from left to right) of an atom and its ions
Neutral<Cation<Anion
Anion<Neutral<Cation
Cation<Neutral<Anion
21
Which of the following has the greatest first ionization energy?
F
Ca
Li
O
22
Which of the following elements has eight valence electrons?
He
Ne
Na
F
23
First Ionization Energy refers to the
energy released by an electron as it leaves an atom
amount of energy required to add one electron to an atom
amount of energy required to remove the outermost electron
24
Nuclear Charge refers to
None of the following!
the atomic number of an element
the charge on the nucleus
the number of protons
