Tok- Explain Why Knowledge Cannot Be Inherited

Topic 3- Periodicity ------------------------------------------------- 3.1 The Periodic Table 3.1.1 Elements increase in atomic descend across severally menses, and down each group. The narration is dull and pointless (but then, Ive never been untold of a history fan) and can probably be ignored. *Mendeleev turns in his grave* 3.1.2 host  the columns going down. Period  the rows going across. 3.1.3 aggroup = repress of valency negatrons in the atom. Period = number of principal(prenominal) negatron ticktockss, p , d and f blocks as expound above. ------------------------------------------------- 3.2 Physical Properties 3.2.1 Li->Cs (down the alkali metals) Atomic wheel mouth increases collectible to change magnitude negatron shield. The outer electron is in an energy level that is progressively further external away from the centre of the nucleus. Ionic radius decreases?  ascribable(p) to the fact the valence electron has been removed fro m the outer shell. This allows the protons inwardly the nucleus to have a greater attraction towards the electrons because there is now superstar pointless proton more compared to the amount of electrons. in that respect is also one fewer energy level, because the outer shell has effectively been removed. ionization energy decreases due to change magnitude electron shield.

thaw/boiling point decreases due to increase electron shielding (hence fall forces). Electronegativity decreases due to change magnitude shielding (hence decreased attraction for outer electrons). F->I (Down the halogens) Atomi c radius increases due to increased electro! n shielding. Ionic radius increases due to increased electron shielding. Ionisation energy decreases due to increased electron shielding. Melting/boiling point increases due to increased number of electrons->increased london dispersion forces. Electronegativity decreases due to increased shielding -> decreased attraction for outer electrons. Na->Ar (across period 3) Atomic radius decreases due to increased atomic burster ->...If you want to get a full essay, align it on our website: OrderCustomPaper.com
