A scientist in California is making a substance consisting of the element lithium and the element chlorine. She found that lithium combines with chlorine in a 2:1 mass ratio. A researcher in Texas wants to also make a substance by combining lithium and chlorine. What ratio of lithium to chlorine should the researcher expect?

The mass ratio will still be 2:1

Lithium and chlorine combine in a 1:1 ratio.

Lithium combines with chlorine in a 1:1 ratio not 2:1 because lithium donates one electron and chlorine accepts that one electron to gain stability. Lithium belongs to 1st group elements that has one electron in its outermost shell.

Whereas chlorine belongs to 7th group elements in the periodic table having seven electrons in its outermost shell so for gaining stability, lithium lose one electron present in its valance shell and chlorine accept that one electron from lithium forming lithium chloride so we can conclude that lithium and chlorine reacts at a 1:1 ratio.
