4/17/2024 0 Comments Color coded periodic tablesThe vertical (up and down) columns of the periodic table (there are 18) are called groups (18)or families(I- VIII).Draw atomic structure of H & He as a class.Mass # is the # of protons PLUS the # of neutrons (each equals 1 AMU).Atomic # is equal to the number of protons or electrons (unless charged).What’s the difference between Mass # & atomic #? Atomic mass (round off for mass # p’s + n’s).Atomic # increasing by 1 means it has one more proton than the previous atom.Atomic # increases by 1, so it has 1 more valence electron than the previous family.The table works because it is based on the structure of atoms, especially the valence e-s (outermost shell).Across a row or down a column the elements’ properties change in a predictable way.An element’s properties can be predicted from its location on the table.Elements are now arranged by increasing atomic number.Published his table in 1869 the newelements were discovered within 16 years.He even predicted the properties of new elements.Mendeleev predicted that the blank spaces would be filled by elements that had not yet been discovered.So he moved the cards into the group it best fit. However, this did not always produce similar groups.Patterns appeared when elements were arranged in order of increasing atomic mass.He listed the elements’ known properties.To help him find a pattern he put all of the known information on individual cards.discovered a system for organizing all of the known elements.1860’s a Russian Scientist named Dmitri Mendeleev.Arranged in rows called periods and columns called groups or families.A way of organizing & classifying elements.29 - Complete fill in the blanks portion of blue packet and turn in. 5 and 6 -Complete yellow Birdley Background: Mendeleev’s table and paste onto p. 28 Periodic Table Trends Notes IQ: On the PT, most elements are non-metals, on left hand side metals, on right hand side non-metals on right hand side metals on left hand side. Modern Periodic Table Periodic – means regular, repeated pattern.Ģ/21 p. OQ: Find the only 2 liquid elements on the PT. The only ones known to create a magnetic field.First elements in groups 8,9, 10 called the iron triad.In space, vast quantities interact with starlight to create spectacular sights such as the Eagle Nebula (seen by the Hubble Space Telescope). Color it GRAY By weight, 75% of the visible universe is hydrogen, a colorless gas.Use Roman numerals I thru VIII to show the families.A Flash animation by Mike Stanfill, Private Hand IQ: What are some ways for organizing information in Science? Why do we organize information?.: Fixed note about gas density to read ".Each of you needs1 of each of the following colors: Red Orange Blue Green Purple Pink Brown : Updated the Excel and PDF files to correctly classify Radon as a gas. : Update (Version 1.1) - Added indicator for radioactive elements, color-coded melting and boiling point data, added the crystal structure (in place of the van der Waals radius), and marked the atomic radius as either the metallic radius (m) or covalent radius (v). Tip: You can create your own mini periodic table poster by printing on 11x17 paper. ![]() You can use this data table for creating trend charts or use lookup functions to use the data within calculations. If you'd like to create your own personal custom periodic table, you can download this Excel file and add your own sets of properties.ĭata: The spreadsheet also includes a worksheet that lists the property data for the elements. This spreadsheet was used to create the printable periodic table above and also contains a worksheet listing the data for various chemical properties.
