Periodicity: Periodic trends across a period and down a group
Fichas del conjunto (10)
- 1Atomic Radius across a periodThere is a decrease in atomic radii as you move left to right across a period this is due to the increase of nuclear charge and an increase in the number of electrons.
- 2Atomic Radius down a groupAtomic radii increases as you move down a group due to an increase in the number of mainshells and an increase in shielding effect.
- 3Ionic Radius across a periodIonic Radius decreases across a period to group 15 where it increases and then it decreases again.
- 4Ionic Radius down a groupIonic Radius increases down a group due to more mainshells of electrons and increase in shielding effect.
- 5Ionization Energy across a periodIonization Energy increases across a period due to an increase in nuclear charge and a smaller radius.
- 6Ionization Energy down a groupIonization Energy decreases down a group because the electrons are farther from the nucleus causing a greater shielding effect.
- 7Electronegativity across a periodElectronegativity increases across a period due to an increase in nuclear charge and the decrease in atomic radius, the nucleus has a greater pull on the nucleus.
- 8Electronegativity down a groupElectronegativity decreases down a group due to an increase in the mainshells and increase in shielding effect, the pull of the nucleus on the electrons is lessened.
- 9Electron Affinity across a periodElectron Affinity increases across a period because of the increase in nuclear charge and the smaller radius makes it easier to pull an electron into the valence shell.
- 10Electron Affinity down a groupElectron Affinity decreases down a group because the valence shell is farther away from the nucleus and there is more shielding effect.
