Template byBill Arcuri, WCSD
Which of the following is a metalloid?
H, Ge, S, Kr or Ag
Template byBill Arcuri, WCSD
Ge
Template byBill Arcuri, WCSD
How did Dmitri Mendeleev organize the elements in
his creation of the periodic table?
Template byBill Arcuri, WCSD
By their atomic mass
Template byBill Arcuri, WCSD
What group number are the Chalcogens?
Template byBill Arcuri, WCSD
Group number 16
Template byBill Arcuri, WCSD
What are the two group names of the elements found
in the two rows under the periodic table?
Template byBill Arcuri, WCSD
The top row is called Lanthanide series and the bottom row is called Actinide series
Template byBill Arcuri, WCSD
What is the relationship between effective nuclear
charge and valance electrons going down a column and
across a row?
Template byBill Arcuri, WCSD
Going down a column, the effective nuclear charge experienced by valance electrons changes far less that it does
across a row
Template byBill Arcuri, WCSD
How are ions formed?
Template byBill Arcuri, WCSD
Ions are formed when electrons are gained or
lost.
Template byBill Arcuri, WCSD
What is the difference between a cation and an
anion?
Template byBill Arcuri, WCSD
A cation is a positive ion whereas an anion is a
negative ion
Template byBill Arcuri, WCSD
What are the trends in atomic radii with each column in the
periodic table?
Template byBill Arcuri, WCSD
Atomic radius increases from top to bottom within
each column.
Template byBill Arcuri, WCSD
Arrange the following in order of increasing atomic
radius...Na, Be, Mg
Template byBill Arcuri, WCSD
Na, Mg, Be
Template byBill Arcuri, WCSD
Why does atomic radius decrease from left to right within each row of the periodic
table?
Template byBill Arcuri, WCSD
The increase in effective nuclear charge as one moves across the row steadily draws the valence electrons
closer to the nucleus, causing the atomic radius to decrease.
Template byBill Arcuri, WCSD
What is ionization energy?
Template byBill Arcuri, WCSD
The minimum energy required to remove an
electron from the ground state of the isolated gaseous atom or ion
Template byBill Arcuri, WCSD
Which show a lower ionization energy, the alkali metals or the noble gases?
Template byBill Arcuri, WCSD
The alkali metals.
Template byBill Arcuri, WCSD
Arrange the noble gases in increasing ionization energy
order
Template byBill Arcuri, WCSD
He, Ne, Ar, Kr and Xe.
Template byBill Arcuri, WCSD
Which has a greater ionization energy: an s- and p-block
element or a transition-metal element?
Daily Double!!!
Template byBill Arcuri, WCSD
The s- and p-block elements
Template byBill Arcuri, WCSD
Which will have the greater ionization energy, Ca or S?
Template byBill Arcuri, WCSD
S
Template byBill Arcuri, WCSD
As an atomic number increases the number of _____ also increases.
Template byBill Arcuri, WCSD
Electrons or protons.
Template byBill Arcuri, WCSD
What are valance electrons?
Template byBill Arcuri, WCSD
An electron in the outer shell of an atom.
Template byBill Arcuri, WCSD
Which element’s electron configuration ends with 4p3?
Template byBill Arcuri, WCSD
As
Template byBill Arcuri, WCSD
What is the electron configuration of Xe using noble gas notation?
Template byBill Arcuri, WCSD
[Kr]4d105s25p6
Template byBill Arcuri, WCSD
Write the electron configuration for the following
ions:1. Ga3+
2. Cr3+
Template byBill Arcuri, WCSD
1. [Ar]3d10
2. [Ar]3d3
Template byBill Arcuri, WCSD
Explain electron affinity
Template byBill Arcuri, WCSD
The energy change that occurs when an electron is added to a gaseous atom is called the electron affinity because it measures the
attraction, or affinity, of the atom for the added electron.
Template byBill Arcuri, WCSD
When an electron is added what happens to the atoms?
Template byBill Arcuri, WCSD
Energy is released when an electron is
added.
Template byBill Arcuri, WCSD
Which group has the most negative electron affinities?
Template byBill Arcuri, WCSD
The Halogens.
Template byBill Arcuri, WCSD
Why do the noble gases have a highly positive electron affinity?
Daily Double!!!
Template byBill Arcuri, WCSD
The Noble Gases already have a full
outer shell and therefore occupying a
higher-energy sub-shell is
energetically very unfavorable
making their electron affinities very
positive
Template byBill Arcuri, WCSD
How do electron affinities change moving down a group?
Template byBill Arcuri, WCSD
They don’t change! Not very much
anyways..
Template byBill Arcuri, WCSD
What are the properties of metals?
Template byBill Arcuri, WCSD
Shiny luster, conduct heat and electricity and are malleable
and ductile
Template byBill Arcuri, WCSD
What is an ionic substance?
Template byBill Arcuri, WCSD
A compound of metals with nonmetals.
Template byBill Arcuri, WCSD
As atomic number increases what happens to the
melting and boiling points of the halogens?
Template byBill Arcuri, WCSD
Since they are all typically nonmetals, their melting and boiling points increase with increasing atomic number.
Template byBill Arcuri, WCSD
Write the electron configuration for Ca and
Ca2+
Template byBill Arcuri, WCSD
Ca: [Ar]4s2
Ca2+: [Ar]
Template byBill Arcuri, WCSD
Why is O2- larger than O?
Template byBill Arcuri, WCSD
O2- is larger than O because increased repulsions that accompany addition of electrons
cause the electron cloud to expand
