Unit 1: Elements

Unit Objectives:  At the completion of this Elements unit,

1. I can identify the seven (7) diatomic elements. (CK12 Sections 2.11, 10.1)

2. I can locate the various groups and periods in the periodic table. (CK12 Section 6.4)

3. I can identify where metals, non-metals, and metalloids are located on the periodic table and explain how their physical & chemical properties differ from each other. (CK12 Sections 6.5, 6.6, 6.7)

4. I can identify the state of matter each element exists in at room temperature. (CK12 Section 6.4)

5. I can determine the number of subatomic particles in an isotope or ion (cation/anion) based on the atomic number, mass number, and charge. (CK12 Sections 4.16, 4.17, 4.18, 6.16)

6. I can explain how the ground and excited states of electrons influence the type of electromagnetic radiation emitted, especially visible light. (CK12 Sections 5.1, 5.5)

7. I can explain the structure of the atom based on the modern atomic theory using the terms: principle energy level, sublevels, and orbitals. (CK12 Sections 5.12, 5.13)

8. I can write electron configurations of atoms and ions using orbital, dot, and exponential notation. (CK12 Sections 5.15, 5.17, 5.18, 8.1, 5.20) 

9. I can identify, apply, and explain the periodic trend of atomic radius. (CK12 Section 6.15)
