The element with atomic number 37 is Rubidium (Rb) and the element with atomic number 52 is Tellurium (Te).
Since Rubidium is a metal and Tellurium is a non-metal, the bond between their atoms would most likely be an ionic bond. Rubidium would donate an electron to Tellurium, resulting in Rubidium becoming a positively charged ion (Rb+) and Tellurium becoming a negatively charged ion (Te-). These ions would then be attracted to each other due to their opposite charges, forming an ionic bond between the two atoms.
