THE HYBRIDISATION OF ORBITALS

HYBRIDISATION: it is a phenomenon, mixing up of two or more atomic orbitals of different energies and form an identical hybrid orbital. SP3 HYBRIDISATION: the shape of this molecule is tetrahydral shape. the bond angle is 109.28' this is formed by the combination of one S and 3P orbitals. four SP3 hybrid orbitals are formed. SP2 HYBRIDISATION: the shape of the molecule is planer triangular. the bond angle is 120°. this is formed by the combination of one S and 2P orbitals. three SP2 hybrid orbitals are formed. SP HYBRIDISATION: the shape of the molecule is linear. the bond angle is 180°. this is formed by the combination of S and P orbitals. two SP hybrid orbitals are formed.

THE STARSHIP(SPACE-X) JOURNEY OF EARTH TO MARS

space x is a private company. The founder of this company is Elon Musk. What is the Starship program? The specific Starship gets to Mars and back to the earth. the starship is a spacecraft.  Space x's grandest upcoming rocket was once known as the interplanetary transport system. the big Falcon rocket  but most recently it has settled on the name Starship. space x founder Elon Musk has announced a complex and ambitious plan to put crewed starships on Mars in the coming decades.  The plan involves several flights and re flights of both Starship vehicles and the super-heavy boosters. Ultimately the goal of Elon Musk is to have a system through which hundreds of people at a time can travel to Mars.  Whether to colonize or just to visit, at a relatively low cost. if the system of Elon Musk proposes really does run at optimal speed, like a well-oiled train line, interplanetary travel May become something we begin to see a lot more of an important part of the space fairing...
