CHEM.6.D — Vertical Alignment
Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.
illustrate how matter is made up of particles that are too small to be seen such as air in a balloon.
compare and contrast elements and compounds in terms of atoms and molecules, chemical symbols, and chemical formulas;
use the periodic table to identify the atoms and the number of each kind within a chemical formula;
model basic atomic structure and relate an element's atomic structure to its bonding, reactivity, and placement on the Periodic Table;
analyze and interpret elemental data, including atomic radius, atomic mass, electronegativity, ionization energy, and reactivity to identify periodic trends.
construct models using Dalton's Postulates, Thomson's discovery of electron properties, Rutherford's nuclear atom, Bohr's nuclear atom, and Heisenberg's Uncertainty Principle to show the development of modern atomic theory over time;
describe the structure of atoms and ions, including the masses, electrical charges, and locations of protons and neutrons in the nucleus and electrons in the electron cloud;
CHEM.6.D
calculate average atomic mass of an element using isotopic composition; and
construct an argument to support how periodic trends such as electronegativity can predict bonding between elements;
CHEM.6.D — Breakout of skills
Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.
The student is expected to
calculate average atomic mass of an element using isotopic composition
