an unstable atom: an atom whose nucleus can change its composition
What is radioactive
200
h/she developed the modern atomic theory
Who is John Dalton
200

200
co-invented spectrascope with his partner; award named after he and his partner

h/she became known as the fa/mother of nuclear physics; credited with the first splitting of an atom
Who is Ernest Rutherford
500
invented plastic... PRETTY STRAIGHT FOWARD!!!
Who is Leo Baekeland
500
THIS ONE IS VERY HARD TO GET: the theory of structure provided dramatic new clarity of understanding, and a reliable guide to both analytic and especially synthetic work. As a consequence, the field of organic chemistry developed explosively from this point; idea of assigning certain atoms to certain positions within the molecule, and schematically connecting them using what he called their valences; benzene ring structure
Who is August Kekule
500
the # 1 most important thing about h/her: the creation a theory of radioactivity
Who is Marie Curie
