I have a little problem with chemistry, and i really want to know best way of revising it, so would you plz give me best advise possible

Below are the following things that you need to follow to ace in chemistry:

1. Firstly, understand the concepts and make a note of it.

2. Highlight all the important points and formula.

3. Practice as many questions as you can.

4. While revising, don't start reading from the first page of your textbook. Rather, go through the notes that you have made.

5. Make sure you know what are you good at - organic or inorganic chemistry. If you are not good at organic chemistry then try to understand the basics first and make inorganic chemistry stronger.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
