Decay chains exist because radioactive elements remain radioactive regardless of decays.

radioactive elements require multiple decays in order to release all of their radiation.

radioactive elements can decay into stable or unstable elements.

radioactive elements require large amounts of time to decay to a stable element.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

To calculate the molarity of a solution, you need to know the moles of solute and the
