pls post a chart on the following trends of elements of periodic table and their compounds.

1. lattice and hydration energy
2. polarisibility
3. colour of compounds
4. thermal stability of compounds
5. common acidic and basic trends and detection principles
6. predicting ionic and covalent properties.
7. dipole moment
8. technique to write reactions (without memorising and less use of
balancing methods)
9. solubility of elements of periodic table in polar and non- polar solvents.
10. additional tips on solid state and crystal lattice and structure.
11. any other relevant information......

chemistry is not that bad afterall
start answering

Electrons are arranged in shells, each containing a maximum of 2(((n+1)/2)^2) if n is odd and 2(((n+2)/2)^2) if n is even, where n is the shell number, electrons. Chemical reactions occur because a complete outer shell is the state of lowest energy, so, in ionic bonding, metals lose electrons and non-metals gain electrons then they are attracted to each other by electromagnetic forces. Covalent bonding is where electrons orbit both electrons, thereby filling shell spaces in both atoms. A more reactive element will take the place of a less reactive element in a substitution reaction and elements will react in whetever way will create a complete shell with the lowest bonding energy. More reactive elements form compounds with greater thermal stability. The reactivity of metals increases with atomic number but the reactivity of non metals decreases with atomic number. The colour is darker for heavier compounds and precipitates of metals reflect higher frequencies when the metal is more reactive. Metals form basic compounds whereas non metals form acidic compounds. Lighter compounds tend to be more solouble.
