formal sentence structure
The element least likely to be found in the molecules of living organisms is francium. Francium is a highly reactive and radioactive element that is extremely rare in nature and has a very short half-life.
Fluorine is the element in group 17 (halogens) that is the least likely to lose an electron because it has the highest electronegativity in the group. Its strong attraction for electrons makes it more stable when gaining electrons rather than losing them.
Helium is the noble gas least likely to form a compound with another element because it has a full outer electron shell, making it very stable and unreactive.
Noble gases, such as helium and neon, would be least likely to occur in an organic functional group since they do not typically form chemical bonds with other elements.
It is difficult to determine the least likely element combination without context. However, in general, elements that are far apart from each other in the periodic table are less likely to form stable combinations due to differences in electronegativity and bonding capabilities. For example, combining a noble gas with a highly reactive metal is unlikely to form a stable compound.

Plutonium is least likely to have been a component of Earth as it is a man-made element that is not naturally occurring in significant quantities.
Gustave Flaubert was a nineteenth-century novelist. His style is defined as 'realist' and he is a precursor of the modernist style which developed around the first part of the 20th century (around WWI). He is not, in France at least, classified as a 'modernist'.
Fluorine is the element in group 17 (halogens) that is the least likely to lose an electron because it has the highest electronegativity in the group. Its strong attraction for electrons makes it more stable when gaining electrons rather than losing them.

Noble gases, such as neon or argon, are least likely to form ionic bonds with sodium since they already have a full valence shell and do not readily gain or lose electrons.
