2022-2023 Objectives Of Electron Configurations, Atomic Mass And Periodic Table

Each student will be able to:

1) Explain the difference between Medeleev and Moseley's Periodic Table.

2) Explain the relationship of an element's position on the Periodic Table to its atomic number
.
3) Describe the Modern Periodic Law

4) Relate the position of an element on the Periodic Table to its Electron Configuration (and number of valence electrons). In other words, be able to write the electron configuration (and number of valence electrons) for the highest energy level electrons (i.e. S 2s² 2p⁴) from the Periodic Table.

5) Relate the chemical charateristics to the Family elements and how Electron configuration detemines it.

6) Give appropriate Elements for the Groups, Periods, and other designated elements including metals, non-metals, and metalloids (semi-metals).

14) Student will need to memorize the seven diatomic elements and their phase (i.e. solid, liquid or gas) at room temperature.

15) Students need to be able to locate the following on their Periodic Table

• Period,Group,Alkali metal, Alkaline Earth metals, Transition Elements, Inner Transition Elements,Lanthanoid series, Actinoid series, Noble or Inert Gases, Halogen, Nitrogen Family, Oxygen Family, metals, non-metals, semi-metals or Metalloids, (s-,p-,d-,f-block elements), phase of elements @20degreeC.
