An electron has the same amount of energy in all orbitals this is not true because depending on how much enegry it has will depend on how many orbitals it has.
An electron has the same amount of energy in all orbitals.
D electrons exist in - This statement is not true about Bohr's model of the atom because Bohr proposed that electrons move in quantized orbits around the nucleus, rather than existing as continuous particles.
It is true that an atom has a nucleus. As for which model of the atom is thought to be true, at the present time we use a model based upon quantum mechanics which differs significantly from the early Rutherford or Bohr atomic models.
Yes, it is true.
Niels Bohr in fact based his model on the hydrogen atom. However, I wouldn't say that the Bohr Model can be correctly applied to ANY atom. Whilst it is an excellent approximation it is not truly accurate. Please don't forget that the Bohr Model is just that, a model, and a model is never as accurate as the real thing.
Yes, Bohr improved upon Dalton's atomic theory by introducing the concept of quantized energy levels for electrons in an atom. He proposed that electrons orbit the nucleus in specific energy levels or shells, which can only hold a specific number of electrons. This model provided a better explanation for the stability and spectral lines of atoms.
Yes, it is.
In the context of the plasma state of matter? Perhaps. I don't know.

Electrons can exist only in certain allowed discrete energy states/ Photon absorption and emission are the result of transitions between energy states/ Electrons with more energy have orbits further from the nucleus
True. The model of the atom has evolved significantly since the 1930s, moving from the Bohr model to the quantum mechanical model. The discovery of subatomic particles, such as protons, neutrons, and electrons, led to a more complex understanding of the atom's structure.
True. Hydrogen-1, also known as protium, is the standard used for the relative scale of atomic masses. Its mass is defined as exactly 1 atomic mass unit (amu) on the atomic mass scale.
Bohrium was named in honor of Niels Bohr, a Danish physicist known for his contributions to atomic theory. This element was named after Bohr because of his groundbreaking work in understanding the structure of atoms, which laid the foundation for the discovery of transactinide elements like bohrium.
I would guess, it's because Bohr's layered model correctly explains connections between atoms (i.e. molecules) and radiation, but on the hand quantum mechanics say that electrons are exactly not kept nicely with orbits- they are all over the place.
