Atoms and Periodic Table Review

The modern periodic table of elements is arranged by  (a)  

• Number of neutrons
• State of matter
• Atomic number (protons)
• Atomic Mass

The man who is credited with the publishing the first periodic table is (a)  

• Dmitri Mendeleev
• Albert Einstein
• Isaac Newton
• Devin Elementus

The Group Number can tell us -

• how many protons are in the nucleus and which elements are most different

• the number of valence electrons and which elements are most alike

• if it's an isotope

• if it's an ion

Match

• Noble Gasses - Inert (non-reactive)

• Group 17

• Alkali and Alkaline Earth Metals (highly reactive)

• Group 18

• Halogens (Highly Reactive)

• Groups 1 - 2

Match properties

• Nonmetal

• brittle (not malleable, not ductile), insulator, dull (no luster)

• Metal

• malleable, ductile, conductive, high luster

• Metalloid

• may or may not be malleable or ductile, semi-conductor, low luster

Match the following

• down (column)

• Another name for Group

• across (row)

• Group goes

• Family

• Period goes

If you changes the number of...

• it creates a different atom; it's the atom's identity

• electrons

• it creates an ion; the once neutral atom gains a charge and is attracted to other ions

• neutrons

• it creates an isotope; it might be heavier or lighter but it doesn't act all that differently

• protons
