Periodic Table and Basic Particle - Revised 2015
Essential Questions (EQ2): Are there any basic particles?
For 2015-2016: Need to memorize the 7 diatomic elements and their phases/(state of matter) at room temperature.
Each student will be able to:
- Explain the difference between Medeleev and Moseley's Periodic Table. [3.1]
- Explain the relationship of an element's position on the Periodic Table to its atomic number (i.e. Periodic law)[3.1](3.1).
- Describe the Modern Periodic Law
- Relate the position of an element on the Periodic Table to its Electron Configuration.[3.2](3.3).
- Relate the chemical characteristics (reactivity) to the Family elements and how Electron configuration determines it.(3.3)
- Give appropriate Elements for the Groups, Periods, and other designated elements including metals, non-metals, and metalloids (semi-metals). [3.2](3.1,3.2).
- Students need to be able to locate the following on the 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.
- Describe what Coulombic force (both attractive & repulsive) and the two major factors that affect the strength of the Coulombic Force (charge on the nucleus & electron).
- Define covalent atomic radius, van der Waals radius, and atomic radius in metals. State and explain why (using Coulombic force, C.F.) how the atomic radii changes as you go down a Group and across a Period. [3.4](3.4).
- Define 1st Ionization Energy (IE) and give the trends for IE as you go down a Group and across a Period. Be able to explain the trend using C.F.(not Shielding effect). Also, state the two Exceptions for Period 2 & 3 (2 for each period). [3.4](3.4).
- Define Higher Ionization Energies (IE) and explain how they can explain the charge on the element's ion. (i.e. Al3+) [3.4] (Not responsible for in 20015-2016)
- Define Electronegativity (EN) and state(including why using C.F.)the general trends as you go down a Group and across a Period. [3.4](3.4)
- Explain how the ionic radius compares to the atomic radius for Metals and then for Non-metals. 'DO NOT usually explain general trends across Period'. Down a Group is same as Atomic radii. [3.4](3.4)
- State the difference between Metals and Non-metals for the characteristics of IE,EN,(Luster, Deformability,heat/electrical conductivity, charge 2015-2016 Learner not responsible), and phase (at room temp). [3.4].
- State and explain why (using other trends)the trends for Metallic Characteristics as you go down a Group and across a Period. [3.4].
- Be able to explain how using the concept of a mole that one can relate number of basic particles and mass of those basic particles even though particles are too small to count or weigh individually.
- Be able to do mole calculations for elements (mass to mole, mole to mass, mole to number, number to mole).
Basic Particles - Example of Use of Periodic Table
- Malleable and ductile and deformability (Not for 2014-2015)
