1 answer:
Answer: has zero mass
is an electron
has a -1 charge
is electromagnetic energy
Explanation:
A beta-particle is an electron emitted from the nucleus of an atom following the decay of a neutron into a proton. Beta rays are deflected by a magnetic field in a direction that indicates a negative charge, thus they are electromagnetic in nature.
The beta particle released is basically a electron with -1 charge and no mass.
General representation of beta particle in the form of given as
where,
Z represents Atomic number
A represents Mass number
X represents the symbol of an element

A molecular formula represents the exact number of atoms present for each element in the compound.
For carbon atom: =
( as molar mass of carbon is 12 g/mol)
Now, 6 carbon atoms are present and rest are hydrogen atoms i.e. 6
Thus, formula becomes (
Now, check for unsaturation:
Degree of unsaturation =
Substitute the value of x and y,
Degree of unsaturation =
=
= implies one ring and three double bonds.
Thus, formula comes out to be i.e. benzene ring.
