Helium has the highest first ionization energy and francium has the lowest first ionization energy.
Food engineering focuses on inventing ways to make food more accessible to populations. This can be done, for example, by genetic modification.
three groups bound to it with no lone pairs
The lone pair repels the electrons of the adjacent bonds more so than does a bonding pair of electrons, so thus alters the molecular geometry of the molecule.
The food we eat is fresher because it is treated with preservatives.
