History
This Russian chemist created the first periodic table by arranging elements by increasing mass and leaving blank spaces for undiscovered elements.
Who is Mendeleev?
Type of elements found mainly on the right side of the periodic table.
What are nonmetals?
A set of elements on the periodic table in the same column is called this.
What is a group (family)?
The name of a group of elements with mostly 8 valence electrons which are unreactive or inert.
What are the noble gases?
Electrons in the outermost energy level of an atom.
What are valence electrons?
This Swedish chemist came up with a standardized system of element names and symbols, including using superscripts to represent elements combined as compounds.
Who is Berzelius?
These elements are found along the "stair step" of the periodic table and have properties of both metals and nonmetals.
What are metalloids?
A row on the periodic table is called this.
What is a period?
The name of an extremely reactive group of elements with one valence electron.
What are the alkali metals?
What is an electron dot notation (diagram)?
This English physicist discovered a way to determine the atomic number of elements, thus leading to a modern periodic table arranged by increasing atomic number.
Who is Moseley?
These types of elements exist mostly as solids that are dense and highly conductive.
What are metals?
As you go across a period, atomic radius does this.
What is decreases?
The name given to Groups 3-12 in the middle of the periodic table, most having one to two valence electrons.
What are the transition metals?
Name given to Groups 13-16 on the periodic table containing metals, nonmetals, and metalloids. These groups are also named for the first element in the group.
What are mixed groups?
This German chemist noticed that elements with similar properties seemed to occur in groups of three which he called triads.
Who is Dobereiner?
These types of elements exists as gases, liquids, or dull, brittle solids and are poor conductors.
What are nonmetals?
As you go down a group, atomic radius increases because of this.
What is another energy level added to the atoms?
The name of the highly reactive group of elements with 7 valence electrons.
What are the halogens?
States that the properties of elements display predictable, repeating patterns when arranged by increasing atomic number.
What is the periodic law?
This scientist discovered that when elements are arranged by increasing atomic mass, pairs of elements with similar properties differed by multiples of eight, which he called the law of octaves.
Who is Newlands?
These types of elements are found on the left side of the periodic table and are highly reactive forming cations.
What are metals?
Arrange the following elements by increasing electronegativity: oxygen, lithium, fluorine, carbon.
The name of the group of elements located in the two rows below the periodic table, typically having 2 valence electrons.
What are the inner transition metals?
A measure of an element's ability to attract and hold electrons when bonded to other atoms.
What is electronegativity?
