Chemistry Oxidation abreviations

QuestionAnswer
Who first organized 33 elements into the four categories on gases, metals, nonmetals, and earth in the 1700s? Antoine Lavoisier
What two things were discovered that led to the discovery of many more elements? Electricity & spectrometer
What occurred in the mid-1800s that led to the manufacture of petrochemicals, soaps, dyes and fertilizers which led to the discovery of more elements? The Industrial Revolution
What is the name of the English chemist who in 1894, realized that when elements were arranged in order of increasing atomic mass, their properties repeated every eighth element? John Newlands
Repeating patterns are referred to as periodic
What was the name of John Newland’s law explaining his arrangement of the elements in 1894? Law of octaves
What are the names of the German chemist and Russian chemist who in 1869, demonstrated a connection between element properties and the atomic mass? Lothar Meyer and Dmitri Mendeleev
Who is often referred to as the “Father of the Periodic Table”? Demitri Mendeleev
What ended up being wrong with Mendeleev’s table? Once atomic masses were measured more accurately, some of the elements needed to be rearranged and no longer “fit” into the correct columns with elements having similar properties.
Who was the English chemist, in 1913, who proposed that the elements should be arranged by increasing order of atomic number instead of increasing atomic mass? Henry Moseley
Does the modern periodic table have the elements arranged in order of increasing atomic mass or increasing atomic number? increasing atomic number
The 18 vertical columns on the periodic table are called groups or families.
Groups 1-2 and 13-18 are called the main group or representative elements.
Group 1 elements are called alkaline metals
Group 2 elements are called alkaline earth
Group 18 elements are called noble gases
Group 17 elements are called Halogens
They are called salt formers
Group 16 elements are called chalcogens.
the halogens are also called the fluorine family.
The 7 horizontal rows of the elements are called periods or series.
The horizontal rows represent the energy levels
26. The 8 elements that border the staircase are called metalloids
metalloids have properties of both metals and nonmetals. They are good semi-conductors
metaloids are often used in electronics, especially silicon and germanium.
Elements to the left of the staircase are metals
Elements to the right of the staircase are non-metals
The periodic law states that when the elements are arranged in order of increasing atomic number the properties of the elements repeat
The atomic number increases from --- and ---- left to right and from the top to bottom
the number of electrons increases from ---- and ----- left to right and from the top to the bottom
The distance from the nucleus to the outer electron of an atom is called the atomic radius
The distance from the nucleus to the outer electron of an ion is called the ionic radius.
The energy needed to remove the last electron from an atom is called the ionization energy.
The attraction of an atom for an electron is called the electronegativity.
Where on the periodic table is the most metallic element? lower lefthand corner
Where on the periodic table is the most nonmetallic element? Upper right hand corner
Where on the periodic table is the element with the highest ionization energy? Upper right hand corner
Do cations tend to be larger or smaller than their atom? smaller
Do anions tend to be larger or smaller than their atom? larger
Group 1 elements have how many electrons in their outer energy level? 1
Do members of Group 1 tend to lose or gain electrons? lose 1
Lewis electron dot diagrams are drawn to represent the number of valence electrons
one mono
two di
three tri
four tetra
five penta
six hexa
seven hepta
eight octa
nine nona
ten deca
The rule that elements strive to have full outer levels with 8 electrons is called the octet rule
Sodium Na⁺
Magnesium Mg⁺
Chloride Cl⁻
Sulfide S⁻²
Oxide O⁻²
Hydrogen H⁺
Zinc Zn⁺²
Niride N⁻³
Silver Ag⁺
Amonium
