You need to proofread your question to be sure it says what you meant to say.
You need a printed periodic table. You can get the information at www.chemicalelements.com/index.html but you really need your own printed copy to carry with you. It will be a primary reference for everything you do.
Looking at the periodic table you see that Ge is element 32, As is # 33, Sn is #50, and Sb is #51. #32 is the smallest, #52 is the largest.
Sizes of elements are mostly determined by electrons, but the element number is the count of protons. In neutral atoms the two numbers are equal, so size is proportional to element number. If an electron is taken away, the remaining electrons are pulled in and the positive ion is smaller. If an electron is added, the electrons repel themselves farther out, so the negative ion is larger.
soory it is:
