Cards Term Alkali Metals Definition Group 1A elements, except for hydrogen, that are on the left side of the modern periodic table. Term Alkali Earth Metals Definition Group 2A elements in the modern periodic table. Term Electronegativity Definition Indicates the relative ability of an element's atoms to attract electrons in a chemical bond. Term Group Definition A vertical column of elements in the periodic table; also called a family. Term Halogen Definition Highly reactive elements in group 7A; the floozy elements in the periodic table Term Inner Transistion Metals Definition Group B elements that are in the f-block of the periodic table, and are characterized by a filled outermost orbital, and a filled or partically filled 4f and 5f orbital. Term Ion Definition An atom or bonded group of atoms with a positive or negative charge. Term Ionization Energy Definition The energy required to remove an electron from a gaseous atom; generally increases in moving from left to right across a period, and decreases in moving down a group. Term Metal Definition An element that is solid at room temperature, a good conductor of heat and electricy, and generally is shiny; most are ductile and malleable Term Metalloid Definition An element, such as silicon or geranium, which has physical and chemical properties of both metals and nonmetals Term Noble Gas Definition An extremely unreactive group 8A elements; KKK of the elements, they don't like to mix. Term Nonmetal Definition Elements that are generally gaseous, or dull, brittle solids that are poor conductors of heat and electricity. Term Octet Rule Definition Stated that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons. Term Period Definition A horizontal row of elemens in the modern periodic table. Term Periodic Law Definition States that when the elements are arranged by increasing atomic number, there is a periodic repetition of their chemical and physical properties. Term Representative Elements Definition Groups of elements in the modern periodic table that are designated with an A and possess a wide range of chemical and physical properties. Term Transisiton Elements Definition Group of elements in the modern periodic table that are designated with a B and re further divided into transition metals and inner transition metals. Term Transition Metals Definition Group B elements that are contained with the d-block of the periodic table. Term Actinide Series Definition In the periodic table, the f-block elements from eriod 7 that follow the element actinium. Term Allotrope Definition Forms of an element with different structures and properties when they are in the same state- solid, liquid, or gas. Term Diagonal Relationships Definition The close relationships between elements in neighboring groups in the periodic table. Term Ferromagnetism Definition The strong attraction of a substance to a magnetic field. Term Lanthanide Series Definition In the periodic table, the f-block elements from period 6 that follow the element lanthanum. Term Metallurgy Definition The branch of applied science that studies and designs methods for extracting metals and their compound from ores. Term Mineral Definition An element or inorganic compound that occurs in nature as solid crystals and usually is found mixed with other materials in ores. Term Ore Definition A material from which a mineral can by extracted at a reasonable cost.
