why do Li, Na, K, Cs and Fr all react with Cl in a 1:1 ratio forming substances with similar properties?

    1.Because they are all in the same column on the period table and elements in the same column have similar properties.

    2.Because they all have 1+ charges which is what CL- wants to bond with to form a neutral molecule. all molecules want to be neutral.

    3.Because they all need to lose one electron to have a stable outer shell of 8 electrons. (all molecules want this.)

    take your pick. they are all right.

    this is because li na k cs fr have a minus charge of one and cl has a plus charge of of one also li na k cs fr have 1 valence electron so they can give one off to cl who has 7 valence electrons it is easier to loose one than to gain 7
