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

One similarity and one difference between an element and a mixture of elements

Which is a characteristic of the electron sea model for metallic bonding? molecular orbitals overlap to produce bands. electrons flow easily between metal nuclei. electrons are in fixed positions in the orbitals. atomic nuclei are arranged in an irregular pattern.
