The arrangement of valence electrons in metals can be best described by the
A sea of electrons.
Answer:
atoms are too small to be seen under a microscope
Explanation:
scientists have been always making research on atomic structure which cannot be directly looked through a microscope
The energy of the electron reduces as it moves closers to the nucleus. This is because it moves from a higher energy orbital to a one of lower energy. It does this by releasing a photon with the energy difference of the current energy level, and the energy level it drops too.
