Current view of atomic structure

Topic: Unit 2

Atoms, Molecules, and IONS

Intro to periodic table-names, symbols, atomic numbers

Neutrons, Isotopes, and Mass Numbers

Molecules and IONS

Examples:

Plum pudding and gold foil and planetary models descried the atom in early times	Today’s model is described as a cloud.	Periodic table is set up in repeating patterns	Isotopes and IONS are from the changes in neutron and electron numbers
	Nucleus of protons and neutrons electrons in orbits

Enduring Understanding (s): Atoms are made up of e, p, and n. Information about elements and their components is found on the periodic table. _________________________________________________

Essential Question (s): Name the 4 scientists and their models that helped shape today’s model of the atom? What information can the periodic table give you about the atoms that make up the elements? Distinguish between compounds and molecules; ions and isotopes. _______________________________________________________
