How to Add a many2many Relational Field in Odoo 17
Periodicity
1.
2. What would you like to know? General Knowledge: About the Table How to read it Metalloids The Non-metals Noble Gasses The Halogens The Metals Trends: Left to right Going down (group 7) Going down (group 1) Practice Problems: Problem 1 Problem 2 I’m Done
3. Left to Right Trend Elect-negativity Atomic Radius Why: This occurs because as you go left to right the Number of protons increases and that increases the pull on the shells Back
4. Going down (group 1) Atomic Radius This occurs because there is a smaller amount of protons as you go down the period so there is a smaller pull on the shells. Electro-negativity This occurs because there is more shielding meaning that there is less pull on the valence electrons and that it will be easier to pull one off. Li Fr Fr Li Back
5. Going down (group 7) Atomic Radius F I This occurs because there is a smaller amount of protons as you go down the period so there is a smaller pull on the shells. I F This occurs because there is more shielding meaning that there is less pull on the valence electrons and that it will be easier to pull one off. Back Electro-negativity
11. About the Table Creator: Dimitri Mendelev Why: When the elements are arranged by atomic value certain properties appear and masses do not repeat. (modern periodic law) Fact: many of the element symbols were derived from there Latin root Back
12. How to Read It Periods: the periods are the horizontal rows. The Groups: The groups are the horizontal Columns Noble Gases The Metals The Metalloids Halogens alkaline earth alkaline Transition Metals Non-Metals Back
13. Which pair of elements reacts most readily? A. Li + Br 2 B. Li + Cl 2 C. K + Br 2 D. K + Cl 2 Explanation Back
14. Which of the following properties of the halogens increase from F to I? I. Atomic radius II. Melting point III. Electro-negativity A. I only B. I and II only C. I and III only D. I, II and III Explanation Back
15. The answer is D. its D because Potassium has a higher lower electro-negativity than Lithium so it will react more readily, and Chlorine has a greater pull because it has a higher electro-negativity than BR due to the amount of shielding. Back
16. The Answer is B. Refer to “ going down Group 1 ” and “ going down Group 7 ” Back
