When Niels Bohr refined the model of an atom,what new idea did he include?

1 answer:

5 0

Answer:

Niels Bohr, refined the model of an atom by proposing a quantized shell structure atomic model in order to describe how the electrons are able to maintain stable orbits around the nucleus

Based on the predictions of classical mechanics the electron motion of the Rutherford model was unstable as the electrons where expected to have lost some energy during motion and thus having to come rest in the nucleus

According to the modification by Neils Bohr in 1913, electrons move in shells or orbits of fixed energy and emission of electromagnetic radiation takes place only when electrons changes the orbit in which they move

A compound contains 30. percent sulfur and 70. percent fluorine by mass. the empirical formula of the compound is

iogann1982 [59]

Assume 100 g of compound. This turns percent to mass. Calculate moles:

S ---> 30/32 = 0.9375
F ---> 70 / 19 = 3.6842

get whole number ratio:

0.9375 / 0.9375 = 1
3.6842 / 0.9375 = 3.93 = 4

Answer : SF4

What causes a nucleus to become radioactive?

Sholpan [36]

When the atoms of radioactive elements have an unstable nucleus. As the nucleus tries to become stable, it releases energy (ionizing radiation), and extra protons or neutrons in the form of alpha or beta particles.
