natural element differ for elements because elements or atoms are a basic unit of matter that cosists of negitively changed electrons
have the same number of valence electrons, need the same number of electrons to fill their valence shells
FLourine is the most electronegative element so it likes to grab the electrons from other elements when it is in compounds. If you are comparing two different elements the periodic trend for strong electrnegativity tends to go to the right and up. The trend for the weakest electronegativity goes to the left and down on the periodic table so you could say that Francium is the least electronegative.
because it is radioactive and because it is an alkali metal. but you shouldn't worry about francium because it is one of the rarest elements in the world with as little as 1 gram at any given time.
Because it has 7 electrons in its outermost (valency) shell and getting 8 electrons there would close the shell.
small atomic radius.
If I recall correctly, it's because they don't have any electrons in their atoms. Atoms react in order to get a full set of 8 electrons, and the less electrons an atom has, the more likely they are to react.
Francium and lithium have the same number of valence electrons.

because it has the most number of electrons in the alkali metal group
When electrons are shared between atoms, the nuclei of both atoms experience attraction towards the electrons and vice versa. At a certain distance, the attraction is maximal because the repulsion between the nuclei is small while the attraction of each nuclei to the electrons is strong. Thus, the atoms are held together by their attraction to the shared electrons.
Because in nature the elements seek to either give out electrons of take electrons. So the elements that gives out electrons bonds with the elements that takes electrons so that both of them are "happy"
Because as we know first that positive attracts to neutral, so protons and neutrons are attracted together and remain together in the nucleus. So there is no chance protons or neutrons can be given up because of attraction forces. Whereas electrons on the other hand are negatives and repel each other and whiz around the atom. So elements typically give up electrons because electrons want to stay away from each other because of the strong repulsion forces. Hence they are given typically by the elements.
