the law that states that the repeating chemical and physical properties of elements change periodically with the atomic numbers of the elements
any of several chemical elements that are usually shiny solids that conduct heat or electricity and can be formed into sheets etc.; found to the left of the zig zag line on Periodic Table
an element that is a poor conductor of heat and electricity; found to the right of the zig zag line on the Periodic Table
an element that has properties of both metals and nonmetals; found along the zig zag line on the Periodic Table
the elements of Group 1 of the periodic table (lithium, sodium, potassium, rubidium, cesium, and francium)
size of the atom from center to edge; increases from top to bottom and decreases from left to right on the Periodic Table
Elements from groups 1, 2, and 13-18 in the modern periodic table, possessing a wide range of chemical and physical properties; Outermost s or p sublevel is only partially filled.
elements in groups 3 - 12 in the periodic table, all of which are metals; they form colored compounds in solution
inner transition metals
an element in the lanthanide or actinide series; the highest occupied s sublevel and nearby f sublevel of its atoms generally contain electrons
an electron that is found in the outermost shell of an atom and that determines the atom's chemical properties
an atom or group of atoms that has gained or lost one or more electrons and has a negative or positive charge
