Standard I-Objective 2 Structure of the Atom

Standard I:  Students will understand that all matter in the universe has a common origin and
is made of atoms, which have structure and can be systematically arranges on the periodic table.
Objective 2: Relate the structure, behavior, and scale of an atom to
the particles that compose it.

Enduring Understanding: The periodic table is used to organize elements by structure. A relationship exists between the chemical behavior and the structure of atoms. The periodic
table reflects this relationship. The nucleus of an atom is a tiny fraction of the volume of the atom. Each proton or neutron in the nucleus is nearly 2,000 times the mass of an electron.  Electrons move around the nucleus. The modern atomic model has been developed using experimental evidence. Atomic theories describe the behavior of atoms as well as energy changes in the atom.

“I Can” Statements

  1. I can summarize the major experimental evidence that led to the development of various atomic models, both historical and current.
  2. I can describe the limitations of using models to describe atoms.
  3. I can compare and contrast the relative size, charge, and position of protons, neutrons, and electrons in the atom.
  4. I can identify how the proton number is key to an element’s identity.
  5. I can calculate the relationship between mass and number of atoms as it relate to the gram-sized quantities of matter in a mole.
