Periodic Table
What is the name of the rows and columns on the periodic table?
Rows = Periods
Columns = Groups/Families
What is the name of the elements that border the Zig-Zag line?
The Metalloids
What is a valence electron?
Where is the smallest element located on the periodic table?
Top right of the table.
Which element has the lower electronegativity?
Na or Mg
Na
How do you find the number of valence electrons in an element?
On your periodic table, Because like a good student I wrote them down when the teacher asked!
The most nonreactive family of the periodic table.
The Noble Gases
Which of the following would have the smallest radius
S-2, Cl-. Ar, Ca+2
Ca+2
Define ionization energy.
The energy required to remove ONE electron from an atom.
which atom will have the highest ionization energy and why?
1S2, 1S2 2S2, or 1S2 2S1
1S2, it has a full outer shell
What is the name of the family with 7 valence electron?
The Halogen Family
What is the name of the family that forms an anion with a -1 charge?
The Halogen Family
What type of ion is formed when an element looses electrons?
Which atom is larger S or Po?
WHY?
Po because it has more electron shells
Across a period (left to right) electronegativity ________ (inc/dec)
Down a group electronegativity _________ (inc/dec)
Across a period electronegativity INCREASES
Down a group electronegativity DECREASES
The Modern Periodic Table is organized based on one number. What is this number?
Atomic Number
What is the name of the family that contains the largest atom on the Periodic Table?
The Alkali Metals
Which metal is the most reactive?
Fr
Which element has the higher Ionization Energy?
WHY? Sr or Te
Te, because it is a smaller atom meaning its electrons are close to the nucleus and tightly held onto.
Takes a lot of energy to remove an electron
List the following elements by increasing atomic radius
Fe, S, Ca, F
F, S, Fe, Ca
7
What is the name of the family that will lose 2 electrons to satisfy the octet rule? What is the charge of elements after they do this?
The Alkaline Earth Metals.
Charge = +2
Do noble gasses have electronegativity values? why
no, they have a full outer shell
Define electronegativity, and state the trend
The attraction to electrons, up and to the right
A small atom will have a ________ (high/low) ionization energy and a _________ (high/low) electronegativity.
A small atom will have a HIGH ionization energy and a HIGH electronegativity.
