Answer: The correct formula for phosphorous pentachloride is
because a subscript 5 indicates five chlorine (Cl) atoms.
Explanation: For the given molecule, phosphorous pentachloride, there are 2 atoms present which are phosphorous and chlorine atoms.
Number of phosphorous atoms = 1
Number of chlorine atoms = 5
So, the correct formula for phosphorous pentachloride will be
because the subscript 5 represents the 5 chlorine atoms.
Answer: Another name for beta-minus particle is electron.
Explanation: Beta-minus particle
is released during the beta-minus decay nuclear reaction.
In this nuclear reaction, a neutron gets converted into proton and electron. The electron released is the beta-minus particle.
The charge on these particles is -1 and mass of these particles is negligible.
