Antointe LavoisierAntointe Lavoisier

Known as the “Father of Known as the “Father of Chemistry”Chemistry”

Made a system for naming Made a system for naming the elements. the elements.

Named approximately 23 Named approximately 23 elements including: oxygen, elements including: oxygen, silver, gold, and carbon.silver, gold, and carbon.

Found that water is made up Found that water is made up of hydrogen and oxygen.of hydrogen and oxygen.

Defined the nature of Defined the nature of elements.elements.

John NewlandsJohn Newlands

Organized the first Organized the first fourteen elements by fourteen elements by their chemical their chemical properties.properties.

He called this system He called this system the law of octaves.the law of octaves.

Lothar MeyerLothar Meyer

Created a periodic table Created a periodic table much like the modern much like the modern one. Based upon atomic one. Based upon atomic mass and physical mass and physical properties.properties.

Much of the credit was Much of the credit was given to Mendeleev given to Mendeleev because Mendeleev because Mendeleev published a book of published a book of these ideas first.these ideas first.

Dmitri MendeleevDmitri Mendeleev

Designed one of the first Designed one of the first periodic tables with the periodic tables with the known elements by their known elements by their atomic mass and atomic mass and chemical properties.chemical properties.

Predicted properties of Predicted properties of many undiscovered many undiscovered elements like scandium, elements like scandium, gallium, and germanium.gallium, and germanium.

Henry MoseleyHenry Moseley

Found that each element Found that each element has their own number of has their own number of protons and that the protons and that the number equaled the number equaled the atomic number.atomic number.

Came up with the Came up with the periodic law…which is periodic law…which is when the elements are when the elements are arranged by atomic arranged by atomic number instead of mass, number instead of mass, there is a repetition of there is a repetition of physical and chemical physical and chemical properties.properties.

Trends: Moving Through the Periodic Table

Atomic Radius

Defined as half the distance between adjacent nuclei in a crystal of the element. (Textbook page 163)

When looking from the left side of the periodic table to the right, the atomic radii decreases.

When traveling downward on the periodic table the atomic radii will increase.

Ionic Radius

Atoms can gain or lose electrons. These electrons will come together to make positive or negative ions.

As atoms lose their negatively charged electrons and become positive ions, the ionic radius will always become smaller.

As atoms gain electrons and form negative ions, the ionic radius will always become larger.

As you travel left through the Periodic Table, periods will increase.

As you travel downward through the table, the groups will increase.

Ionization Energy

Ionization energy = the energy required to remove an electron from a gaseous atom.

As you move left through the periods, the ionization energies increase.

As you move down through the groups, the ionization energies decrease.

Definition from textbook page 167

Electronegativity

The electronegativity of an element indicates the relative ability of its atoms to attract electrons on a chemical bond.

The units used are called Paulings. Electronegativity usually decreases as

you move down through a group and increases as you move left through a period.
