A solution of Lithium Fluoride is separated using electrolysis. During this process the lithium ions are attracted to the cathode where they gain electrons to form lithium atoms. Thi...

When revising, it can seem like there is a lot to have to learn. As you practise some exam questions and lose some marks, it can make you feel more and more disheartened. By following...

If I ask your age, the answer is most probably given in years and not in seconds. In Chemistry we use moles and not the number of atoms because they are very small and very large in n...

Even till this day I am still learning how to revise, however when I do revise, I always follow the following fundamental points.- Space Repetition - Active Recall1. Space Repetition ...

To understand isomers, requires understanding of the two different chemical formulae: molecular and structural. The molecular formula is the number of each element found in a compound...

This is a topic which I studied extensively in my master`s project. I am including this in my profile because I think it is a very important area of research and hope that it is convi...

BASES AND ALKALIS A base is a substance which will neutralize an acid to yield a salt and water only. Most oxide and hydroxide of metals are bases e.g. Na2O, K2O, MgO, NaOH, KOH e.t....

Physical Trends Down Group 2:1. Atomic radius increases2. First ionisation energy decreases3. Melting point decreases - size of atom/ion increases so delocalised electrons are ...

BasicsIonic bonding is the transfer of electrons between metals and non-metalsMetals GIVE electronsNon-metals ACCEPT electronsMetals lose electrons to obtain a full outer shell (Noble...

Covalent BondingCovalent bonding is a formation of two atoms sharing a pair of electrons. This type of bonding happens in most non-metal elements as well as in compounds formed amon...
