Periodic Table Vocab. Flashcards
When the elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties is called?
Periodic Law
What’s one of a class of elements that are good conductors of heat and electric currents; ductile, malleable, and shiny?
Metals
What’s an element that tends to be a poor conductor of heat and electric current; non-ductile, non-malleable, and dull?
Non-etal
What’s an element that tends to have properties that are similar to those of metals and nonmetals?
Metalloids
What’s any metal in Group 1A of the periodic table?
Alkali metals
What’s any metal in Group 2A of the periodic table?
Alkaline Earth Metals
What’s an element in Group 8A of the periodic table; the s and p sublevels of the highest occupied energy level are filled?
Noble Gas
What’s a nonmetal in group 7A of the periodic table?
Halogens
What’s one of the Group B elements in which the highest occupied s sublevel and a nearby d sublevel generally contain electrons?
Transition Metals
What’s an atom or group of atoms that has a positive or negative charge?
Ion
What’s any atom or group of atoms with a positive charge?
Cation
What’s any atom or group with a negative charge?
Anion
What’s an electron in the highest occupied energy level of an atom?
Valence Electron
What’s a notation that depicts valence electrons as dots around the atomic symbol of an elements; the symbol represents the inner electrons and atomic nucleus; that’s also called the Lewis dot structure?
Electron Dot Structure
Atoms react by gaining or losing electrons so as to acquire the stable electron structure of a noble gas; usually eight electrons is called what rule?
Octet rule
