Chem Flashcards
What atom model was associated with Neils Bohr’s atomic theory?
Planetary model
What atom model was associated with Dalton’s atomic theory?
Billiard Ball
What was Dalton’s atomic theory?
(1) Elements consist of indivisible small particles (atoms).
(2) All atoms of the same element are identical; different elements have different types of atom.
(3) Atoms can neither be created nor destroyed.
What atom model was associated with J.J. Thompson’s atomic theory?
Raisin Bun
What did J.J. Thomson discover?
Electrons
What did Ernest Rutherford discover?
The nucleus and proposed the existance of protons
What atom model was associated with Neils Bohr’s atomic theory?
Planetary Model
What did Neils Bohr propose?
That electrons move in circular orbits around the nucleus.
What did James Chadwick discover?
Neutrons! (Jimmy Neutron)
What atom model was associated with Schrodinger/de Broglie’s atomic theory?
Quantum model
What does the quantum model have thats special about electrons?
That electrons have distinct energy levels and the electron cloud.
What are the atoms proportions?
Nucleus (protons and neutrons) = most of the weight of the atom
Electrons = most of the volume of the atom
What are isotopes?
Atoms that have the same number of protons but a different number of neutrons
What is group 1 on the periodic table?
Alkali Metals
What is group 2 on the periodic table?
Alkaline Earth Metals
