Metalloids The Atom & Periodic Table Vocabulary 1. Atom -The building blocks of matter 2. Isotope -Atoms of the same element can have different numbers of neutrons 3. Proton -positive charge, are in the center of the atom, determine a substances identity 4. Electron Configuration- tells you where elements electrons are and determines what an element will react with. 5. Neutron-Neutral Charge, are in the center of the atom, determine a substances identity 6. Shell- outer energy level of atom 7. Electron-negative charge, determines an elements reactivity 8. Valence Electrons- electrons in the outer shell of an atom 9. Nucleus- the center of the atom 10.Period- horizontal row 11.Periodic Table- the collection of all known substances in the world 12.Group- vertical columns; they are numbered 1 – 18 13.Element- a substance that can not be broken down into a simpler substance 14.Family- specific name describing one or more groups 15.Atomic #- This defines what the element is or how many protons the element has 16.Metals- left and center part of periodic table, Conduct heat and electricity, Have Luster, Malleable, Ductile, All are solid at room temperature(except mercury) 17.Atomic Symbol- This is the symbol for the element. Could be English or Latin letters 18.Nonmetals- right side of the periodic table, Very abundant in nature, Poor conductors of electricity and heat, brittle, many are gases 19.Atomic Mass-Average Mass of the element or the total number of neutrons and protons in an element 20.Metalloids- – some properties of metals and some properties of nonmetals, They are found along the border between metals and nonmetals, They are semiconductors.
