In niels bohr’s model of the atom, how are electrons configured?

The electrons in Niel Bohr's model are configured in the form of planets orbiting the Sun.

Explanation:

Bohr suggested that electrons revolve around the nucleus in particular orbits that are quantized. These orbits are demonstrated by the letters K. L, M, and N. When an electron captivates energy it goes to a higher orbital, and it moves to a lower orbit when the energy gets discharged. This movement generates discrete spectra that illustrate the reason for quantized levels of energy.

i don,t know so just answer mine

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
