Bohr Models
The electrons found on the out most energy level or shell in an atom
What are valence electrons
What are periodic table families
This trend focuses on how much energy is required to remove one electron from an atom's valence energy level.
Ionization energy
A group
What is the name given to a vertical column on the periodic table?
This type of elements are shiny, malleable, and conduct electricity
What are metals
An atom of this element has two (2) electrons in it's outmost energy level. This atom only has two (2) energy levels.
What is Beryllium
This family has elements that are the most reactive on the periodic table
What are alkali metals
This element on the periodic table has the largest atomic radius of the all the elements
What is Francium (Fr)
Oxygen (O) is a part of this group
What is group 17
This group of elements has characteristics of both metals and nonmetals
What are metalloids
True or False: An atom with only one valence electron on its outmost energy level is less reactive than an atom with eight (8) valence electrons in its outmost energy level
False
This family is the most stable family of elements on the periodic table
What are noble gases
Which of these two elements has a higher electronegativity? Lithium (Li) or K (Potassium)
What is Lithium (Li)
What are the elements in Group 18 commonly called
You would expect to to find dull, brittle solids in this group of elements
What are nonmetals
What is the maximum number of electrons that can occupy the first energy level in the Bohr model?
two (2)
Name the family that includes fluorine, chlorine, bromine, and iodine, known for their high electronegativity and reactivity
Halogens
Which group on the periodic table generally has the lowest electronegativity?
Alkali metals
What is the defining characteristic of elements within the same group on the periodic table?
They have the same number of valence electrons
Give an example of a nonmetal that is solid at room temperature
What is carbon
How does an electron move to a higher energy level in the Bohr model?
By absorbing energy
What is the atomic number of the lightest alkali metal and what is the name of this metal?
Atomic number 3, Lithium (Li)
Explain the relationship between atomic radius and metallic character on the periodic table
Larger atomic radius generally corresponds to increased metallic character
Which group contains elements that are typically non-metals and highly electronegative?
Group 17 - The halogens
List three metalloids found on the periodic table
Boron, Antimony, Tellurium
