Atoms and Periodic Table

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

• Number of Neutrons

• Atomic number (protons)

• State of Matter

• Atomic Mass

The man who is credited with publishing the first periodic table is:

• Dimitri Mendeleev

• Issac Newton

• Albert Einstein

• Devin Elements

The Group Number can tell us-

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

• if it's an isotope

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

• if it's an ion
