Nuclear notations are used to represent the decay of one element into another. The generic formula for a radioactive element is X-M = X-(M-4) + He-4 where X is the symbol for the element, M represents the mass number for the element. An equation for gold-191 may be Au-191 = Au-187 + He-4.

[185/79] Au ==> [181/77]Ir + [4/2]He These figures are fictitious, however, the [4/2]He is the helium nucleus,( alpha particle) which would be emitted.
DPIP substitutes for electron acceptor
After positron emission or electron capture the atomic number is decreased with one.
Simply put, electron capture is a nuclear change that an atom might undergo when there are "too many" protons in its nucleus. This atom is unstable, and an electron from an inner orbit will actually be "pulled into" the nucleus. Once there, the electron will "combine" with a proton, and the proton will be transformed into a neutron. This will result in the formation of a new element as a result of the nuclear transformation.
This is something you must learn for yourself in chemistry class or something, and isnt good to ask for help on the internet for something you should be learning yourself.
This is the isotope erbium-167.

After electron capture a neutrino is released.
[185/79] Au ==> [181/77]Ir + [4/2]He These figures are fictitious, however, the [4/2]He is the helium nucleus,( alpha particle) which would be emitted.
During electron capture, an electron and proton combine and are converted to a neutron.
Electron capture occurs when an electron from the innermost orbital of an atom is captured by a nucleus, which leads to the conversion of a proton into a neutron.
The capture creates a "hole", or missing electron, that is filled by a higher energy electron that emits X-rays.

After positron emission or electron capture the atomic number is decreased with one.
Rubidium-82 decays by K Capture initiating beta+ with a half-life of 1.273 minutes decaying to Krypton-82... 3782Rb + e- --> 3682Kr + e+ + ve
There are three beta decay modes for 40K, and so three equations. The equation for the negative beta decay of 40K: 1940K --> 2040Ca + -10e where the -10e represents a beta particle or electron. The equation for the positive beta decay of 40K: 1940K --> 1840Ar+ 10e where the 10e represents a positive beta particle or positron. The equation for the decay of 40K by electron capture is:1940K + -10e --> 1840Ar + ve
