The following objectives have been adopted wholesale from TCIS and then sequenced to fit naturally together for GSIS students. (Following objectives relate to Glencoe Chemistry: Matter and Change; chapter #8, 9)
McREL:
Standard 8 – Understands the structure and properties of matter
I. Ions and Ionic Compounds
A. Knows that the number of electrons in an atom determines whether the atom is electrically neutral or an ion (i.e., electrically neutral atoms contain equal numbers of protons and electrons; a positively charged atom has lost one or more electrons; a negatively charged atom has gained one or more electrons)
B. Describe the formation of ionic bonds by electron loss and gain
C. Illustrate and explain the formation of ionic ... bonds
D. Name and write formulas for some common ionic ... compounds, using the Periodic Table and a list of ions
E. Teach multivalent metals (limit to 4 simple metals- Cu,Fe, Sn,Pb) including writing formulas with roman numerals and the suffix “ous” and “ic”
F. Describe the oxyacids, oxyanions, specifically (NO3-,ClO3-,CO32-, SO42-PO43-)
G. Name and write formulas for some common polyatomic ionic compounds (CuSO4, CaCO3, etc.)
II. Covalent Molecules
A. Illustrate and explain the formation of ... covalent bonds
B. Name and write formulas for some common ... molecular compounds, using the Periodic Table and a list of ions
C. Describe the formation of single covalent bonds and the formation of diatomic gases (O2, N2, F2) and explain why Nobel gases (Ideal gases) are monatomic (stable octet)
III. Metallic Bonding
A. Illustrate and explain the formation of ... metallic bonds
B. Describe metallic bonding as a positive ion lattice in an electron ‘sea’ to explain malleability and conductivity
