BOHR´S ATOMIC MODEL
Postulate 2: In these orbits it will be fulfilled that the angular momentum of the electron will be an integer multiple of h / 2∏.(Ale)
+Postulate 3: The electron will only emit energy when, in one of these orbits, it passes to another with less energy.(Ale)
Postulate 1: The electron can only rotate in certain circular energy orbits and certain radii. (Ale)

Bohr made a model of hydrogen, which is based on the classical assumption that electrons travel in specific layers, or orbits, around the nucleus. (Ale)

Niels Bohr was a physicist who contributed to quantum mechanics and also did research on atoms. (Ale)

F) How is the periodic table built?
the periodic table is currently composed of 112 elements, 7 lines and 2 extra lines, and 3 groups (solids. liquids and gas) (Cheetah)
E) What does the "spectra" include?
It covers all energy of light extending to microwaves and radio waves
It was proposed where the electrons can have stable orbits around the nucleus and why the atoms had characteristic emission spectra.

The positive charge is not evenly distributed across an atom. Instead, everything is concentrated in the small nucleus. The rest of the atom is an empty space, except for the electrons scattered through it. In Rutherford's model of the atom, electrons move around the massive nucleus like planets orbiting the sun. So his model is called a planetary model. Rutherford did not know exactly where or how the electrons orbit the nucleus.

The spectroscope is an instrument used to measure all the properties of light in a certain portion of an electromagnetic spectrum. The variable that can generally measure is the light intensity but the state of electromagnetic polarization can also be measured

The numbers that we can find in the periodic table can be the atomic number, also can be the atomic weight.
