Periodic Family Characteristics
What is the name of the lower row of elements in the F-block?
Actinide series
What is the family name of the group 1A elements?
Alkali Metals
What is the family name of the group 2A elements?
Alkaline Earth Metals
Which has a higher melting point, alkaline earth metals or alkali metals?
Alkaline earth metals
Which is denser, alkaline earth metal or alkali metal?
Alkaline earth metals
What happens to halogens when moving down the periodic table?
change state as move down the family, with fluorine and chlorine existing as gases at room temperature while bromine in a liquid and iodine is a solid
Transition are what
shiny, lustrous high thermal and electrical conductivity dense high melting points
How many valence electrons do alkali metals have? And how do they look?
1 valence electron shiny, lustrous
How many valence electrons do alkaline earth metals have?
2 valence electrons metallic solids, harder than the alkali metals shiny, lustrous, oxidize easily high thermal and electrical conductivity more dense than the alkali metals higher melting points than alkali metal
How many valence electrons do halogens have?
7 valence electrons
do halogens melting and boiling points increase/decrease when increasing/decreasing the atomic number
Group 17 7 valence electrons melting points and boiling points increase with increasing atomic number
What are the traits of Noble Gases
Group 18 8 valence electrons stable electron octet makes these elements nonreactive (inert) under ordinary circumstances
What is the family name of the group 7A elements?
Halogens
The F-block is part of the transition metal family, but because their final electrons enter an f-sublevel, they are denoted as ____________?
Inner Transition metals
What is the name of the upper row of elements in the F-block?
Lanthanide series
What is the family name of the group 8A elements?
Noble Gases
The largest section of the periodic table, commonly known as D-block, is called by what name?
Transition Metals
Are halogens reactive?
Yes, very reactive
Are the melting points for transition metals high or low?
high melting points
Are alkali metals conductive?
high thermal and electrical conductivity
Are transition metals conductive?
high thermal and electrical conductivity dense high melting points
How do they(alkali metals) increase and decrease?
increasing with atomic mass relatively low melting points, decreasing with atomic mass
How dense are alkali metals?
low densities
Are alkaline earth metals soft?
metallic solids, harder than the alkali metals shiny, lustrous, oxidize easily
Are transition metals hard,soft,what?
they are hard metallic
True or false? Hydrogen can occupy the top position in the Alkali metal family and the Halogen family.
true because Hydrogen exhibits characteristics of both 1A and 7A elements, but is generally considered to be in a class by itself.
Are alkaline earth metals conductive?
very high thermal and electrical conductivity.
