Worrying that there were too many overseas students applying for colleges in UK because of epidemic, Lisa specially applied for other schools in Canada and US as an insurance. “KCL、Toronto、UBC、Minnesota Twin Cities…… about ten in all. I also received offers one by one later the time d...
The quantum mechanical approach is currently used to explain atomic structure. The study of fundamental constituents such as atoms, molecules, substances, metals, crystals, and other aggregates of the matter is where traditional chemistry begins. Let’s now see about some basic terms of chemistry a...
