Chemistry Questions

An atom that loses or gains electrons is called as ion. Gaining of electron is negative charge and is called as Anion and lossing of eectron is called Cation.

When exposed to certain frequencies of radiation, such as radio waves, the subatomic particles called electrons that orbit an atom's nucleus will "jump" back and forth between energy states. Clocks based on this jumping within atoms can therefore provide an extremely precise way to count seconds.It is no surprise then that the international standard for the length of one second is based on atoms. Since 1967, the official definition of a second is 9,192,631,770 cycles of the radiation that gets an atom of the element called caesium to vibrate between two energy states.

SO2 has a net dipole moment and has a bent shape in its structure as water molecule. Hence it is a polar molecule.

Bond breaking is an endothermic process.

Hence, bond breakage needs an amount of energy and uses some energy based on the strength of the bond to break the bond.

The substances in which two or more atoms are attached together are called as molecular substances. 

Properties of molecular substances ::

1. Molecular substances are bonded with covalent bonds

2. Bad heat conductivity

3. Bad electrical conductivity

4. Have low melting points.

Liquid sodium is being considered as engine coolant.
