2022-2023 Objectives of Periodic Table Trends, Mole Concept and Types of Element Grouping

Essential Questions (EQ2): Are there any basic particles?
Each student will be able to:

Periodic Table Trends

Relate the chemical characteristics (reactivity) to the Family elements and how Electron configuration determines it.

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

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. <b>[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 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, and phase (at room temp).

State and explain why (using other trends)the trends for Metallic Characteristics as you go down a Group and across a Period. [3.4].

Mole Concept

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).

Types of Elements

Knowing the LDS value, calculate the chosen class chain. (you can just have handout ready) - Example of Use of Periodic Table
Malleable and ductile and deformability (Not for 2014-2015)
