Which statement best describes how electrons fill orbitals in the periodic table?
electrons fill orbitals in order of their increasing energy from left to right.
electrons fill orbitals in order of their increasing energy from right to left.
elements fill orbitals in order of increasing energy from top to bottom in each group.
elements fill orbitals in order of increasing energy from bottom to top in each group.

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.

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
