Electronegativity means how strongly an atom can attract electrons. The more positive charge an atom has, the better it attracts the negatively charged electrons. However, distance is a factor too, so if the nucleus (where the protons are) starts becoming too large, the strength of the positive charge isn't as large as it would otherwise be.
Basically this means that fluorine is the most electronegative element since it has the most positive charge for its relative size. Elements closer to fluorine have higher electronegativities than elements further from it on the periodic table.
so in other words F is most electro, bc it attracts more electrons to its atom making other atoms Positive

Notice that you have a

:
5
mole ratio between phosphorus and oxygen. This means that, regardless of how many moles of phosphorus you have, the reaction will always need

4
time more moles of oxygen gas.
Use phosphorus' molar mass to determine how many moles you have in that

Answer:
I think it's light production, color change (new/different), gas production (bubbles/fizzing - not boiling), precipitate, and temperature change
