Mode of decay for iron- 53 and iron- 59 , two radioactive isotopes of iron, is to be stated. Concept introduction: Iron has many radioactive isotopes among which four are stable having mass numbers 54 , 56 , 57 and 58 . Two radioactive isotopes of iron are iron- 53 and iron- 59 . Nuclei of radioactive element decompose in various ways. Types of radioactive processes include α particle production, β particle production, γ ray production, electron capture and many others. Beta particle production decay involves the production of beta particle ( − 1 0 e ) that is assigned mass number zero. A helium nucleus 2 4 He is produced in the alpha decay process. Positron 1 0 e is a particle with mass same as the electron, but its charge is opposite to that of electron. To determine: The mode of decay for the isotope 53 Fe .

fcrip = ↓ bandwidth Il temp 32. What impact (increase, decrease, or no change) does each of the following conditions have on the individual components of the van Deemter equation and consequently, band broadening? Increase temperature Longer column Using a gas mobile phase instead of liquid Smaller particle stationary phase Multiple Paths Diffusion Mass Transfer
