Answer:
a visible record (such as a series of colored bands, or a graph) showing the result of separation of the components of a mixture by chromatography.
Explanation:
Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a system on which is fixed a material called the stationary phase.
All three molecular nitrogen, carbon monoxide, and cyanide ion are isoelectronic but CO and CN⁻ are toxic as compared to N₂ because N₂ has very high bond energy due to the presence of triple bonds making it stable in comparison to others.
<h3>What is Isoelectronic species?</h3>
The phrase "isoelectronic species," which means "same electric" or "equal charge," describes two atoms, ions, or molecules with the same electronic structure and the same amount of valence electrons. Chemical species that are isoelectronic often have identical chemical characteristics. It is referred to as having the same isoelectronic or being isoelectronic to other atoms or ions with the same electronic configurations.
