It's been some time since I last updated this blog.
Firstly, I'm proud of myself for getting full marks on the Atomic Structure timed assignment. ((:
On the other hand, getting 10/25 for Atoms, Molecules & Stoichiometry made me reflect on what mistakes I made. )):
Ok, let me recap on what I've learnt.
Firstly,
Now I understand the meaning of Isotopes, Isoelectronics and Isotonics.
Isotopes: Same number of protons.
Isoelectronics: Same number of electrons.
Isotonics: Same number of neutrons.
Next, the definition of Ionisation Energy.
It is the minimum amount of energy required to remove the valence electrons from one mole of gaseous atoms to produce one mole of gaseous ions each with a charge of +1.
Shapes of orbitals.
I am also able to state the electronic configurations of different elements and ions.
Examples.
Electronic Configurations.
'Noble gas' Configurations.
Think I'll just stop here.
Till then,
Feekee signing off.
Next thursday, test on Chemical Bonding.Oh, and Ms Jee got Ng Hui Min and Foo Hui Min mixed up in a document on MI Link. =D
9:35 PM
chemistry time!
