There is two of these questions
Answer is: S<span>AE standard that must be referred to on the label of approved HFC-134a refrigerant recycling machines are </span>J1770 and J2788.
<span>J1770 is to establish the specific minimum equipment requirements for recovery or recycling equipment intended for use with R134a.
</span>J2788 is intended to establish requirements for equipment used to recharge HFC-134a.<span />
Atomic radius- a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons.
Electron Affinity-the electron affinityof an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.
Electronegativity-a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.
Lonization energy- qualitatively defined as the amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.
