How reactive is an atom of sodium(na) and why? sodium (na) is not very reactive because it does not have a full valence shell. sodium (na) is not very reactive because it can only bond with chlorine (cl) to become salt. sodium (na) is very reactive because it does not have a full valence shell. sodium (na) is very reactive because it does not have enough protons in the nucleus.

Which statement is best described as a atom

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.
