What if the water molecule have a straight structure?
The structure of the water molecule Water is a representative ‘polar molecule’. The hydrogen-oxygen-hydrogen bonds that make up the water molecule have an angle of 104.5˚ and appear curved. Because of this…

Polar Molecule & Nonpolar Molecule
Polar molecule Polar molecules have polar covalent bonds between their constituent atoms, and the shape of the molecule is asymmetric. Therefore, the centers of positive and negative charges do not coincide. Just…

Chemical Cell (Voltaic Cell, Daniel Cell)
Electricity production before Volta Before chemical cells, such as dry cells, there was only one thing we knew as a way to produce electricity. That is rubbing amber, glass, or metal. Voltaic…

Activity Series of Metals
Ionization tendency of metal The tendency of metals to lose electrons and become cations is called the ‘ionization tendency.’ The ionization sequence is an ordered list of ionization trends. The greater the…
