Structure of the Periodic Table
Name the vertical columns of the Periodic Table
Groups (or Families)
The periodic table is organized by increasing what?
Atomic number
Who is known as "The Father of the Periodic Table"?
Dmitri Mendeleev
What is the purpose of a Bohr Model?
To show reactivity of elements
What are 3 general properties of metals?
Shiny, malleable, conduct electricity
Name the rows of the Periodic Table
Periods
What is a valence electron?
Electrons in the outermost shell- responsible for reactivity
Who is first credited with applying some sort or organization to the elements?
John Dalton
The number of valence electrons in an atom can be determined by the atom's ____________ number.
Group (Family)
What are 3 general properties of non-metals?
Dull, brittle, do not conduct electricity
Give the period number and group number for Nickel.
Period 4, Group 10
The nuclear charge of an atom will ______________ as you move down a group.
Decrease
Who discovered that atoms should be arranged by atomic number and not atomic weight?
Henry Mosely
The number of energy levels in an atom can be determined by looking at the atom's _____________ number.
Period
Metalloids will have characteristics similar to _______________________.
Metals and Non-metals
Where would I find the Noble Gases on the table?
Group 18
Non- metals reactivity will _____________ across a period.
Increase
Scientists knew that Mendeleev's table was accurate when they discovered elements that Mendeleev had predicted (using his table) had the same ______________ as his predictions.
Properties
What is the "magic" number of electrons that shells 2 through 4 wish to have to make them "complete"
8
Elements in Group 1 of the Periodic Table are called
Alkali Metals
What broader category do the lanthanides and actinides fall into?
The inner transition metals
Why do atoms in the same group have similar chemical properties?
They have the same number of valence electrons, so they have similar reactivity patterns.
They say Mendeleev's table is a work of genius because his table was the first to organize elements based on their ______________ AND ___________.
Weight, properties
Draw the Bohr model for Oxygen
Show me
Who was the scientist that discovered that elements shared similar properties every 8 elements and called these groups of 8 "octaves"?
John Newlands
