The Periodic Table Catalyst Take out your periodic table to answer the following questions: 1. What are the periods and groups on the periodic table? Periods are the horizontal rows and groups are the vertical columns. 2. How do you find the number of neutrons in an atom? How many neutrons are in boron? Atomic mass – atomic number = number of neutrons. 11 – 5 = 6, there are 6 neutrons in boron 3. Draw a Bohr model (electron rings and nucleus) for carbon. 29L 11/14/11

VI. Families and periodsVI. Families and periodsA. The number of rings and number of
electrons on the last ring of any given element determines it position on the period table.
B. Groups- vertical columns*Similar chemical properties

C. Each horizontal row on the periodic table is called a period. *Not alike, but have the same number of energy levels

Isotopes = Atoms of the same element that have different numbers of neutronsExample: Carbon-12, Carbon-13, and Carbon-14Think-Write-Pair-Share1. How many neutrons does each one have? How many protons and electrons?2. What about for hydrogen? There is hydrogen-1, hydrogen-2, and hydrogen-3. 29R

Metals are elements that are good conductors of electric current and heat. They are also shiny and bendable. The majority of elements in the periodic table are metals.
Physical PropertiesLuster (shininess), malleability (can be hammered into flat sheets), ductility (can be rolled into long wire), and conductivity (thermal, transfer heat, and electrical, transfer electric current)
Chemical PropertiesReactivity – the ease and speed with which a substance reacts with other substances, Na reactive and Au unreactiveCorrosion – the gradual wearing away of a metal due to a chemical reaction, rust
