The very first element of the periodic table that was in a dilemma that whether it should be placed with metals or with non-metals. Actually some of the properties of the hydrogen gas resembles with metals like - Its cationic form ( H+) ion is more stable than its anionic form (H-) even though H- obeys octet rule i.e, just like metals it always ready to donate its electron. Just like metals of group 1 and 2 , it also form several stable compounds with Chalcogens and halogens family like HCl, HBr, H20, H2S - they all are very popularly known compounds. It also resembles with alkali metals in valence shell electronic configuration (ns1). On other side its several properties resembles with the non- metals like - As chalcogens form compounds with alkali metals (eg- NaCl, KBr etc), hydrogen also do so like NaH, KH etc. Although H+ is more stable than H- but alike chalcogens ,hydrogen is also ready to accept one electron to get stable.
Chemicals like Laughing gas, Hydrochloric acid, Nitric acid and several others are going to be explained in the most easiest and practical ways. Practical situations like existence of fire and the chemical processes involved in this would be discussed. Moreover human body chemicals and nutrients are also being discussed in the most interesting way !
