HINT: Those lewis dot structures give the number of valence electrons each element has. the number of valence electrons is contained in the outermost shell in the atom. what this means is that these electrons that participate in chemical reactions because they are farthest away form the nucleus. When you look at the vertical groups, all the elements belonging to those groups are arranged in terms of the number of valence electrons they have. Remember, think about which element would satisfy its octet if it is to form a bond with another element. octet means that there are 8 electrons in the valence shell. Metals will lose electrons to get closer to octet while non metals will gain electrons to get to octet.

@Photon336 so the amswer is Lithium and flourine?

mayankdevnani · Answer

nope @Jalilforeal

jalilforeal · Answer

Carbon is not very reactive, but it does comes in many other compounds.

mayankdevnani · Answer

i think Lithium,Carbon and Fluorine is correct answers

jalilforeal · Answer

All three?

mayankdevnani · Answer

First three

mayankdevnani · Answer

what about you @imqwerty

mayankdevnani · Answer

Carbon forms covalent compounds.

1st of all take a look at this 
this isn't so useful but still

imqwerty · Answer

after this

as @Photon336  said

the outer most electrons take part in reaction and they react to become stable

they become stable by completing their octet

here lithium and fluorine need only 1 electron to complete their octet 
but carbon needs to either lose 4 electrons or gain 4 electrons which is more difficult as compared to lithium and fluorine case

imqwerty · Answer

Carbon is not very reactive
Well it makes many different sort of compounds tho but it doesn't prove that its more reactive that Lithium and Fluorine

mayankdevnani · Answer

Oh ! i misread the question !
Most two elements, then it would be Lithium and Fluorine

jalilforeal · Answer

Oh okay

mayankdevnani · Answer

If your question say, how many will react ?
Then answer will probably first three :)
