Schrodinger and Heisenberg state that electrons cannot be predicted in 1927. It was stated that the more precisely the position of some particles are determined, the less precisely its momentum can be known.
Heisenberg/Schrodinger
It was around 1926 - 1927.
Schrödinger and Heisenberg, around 1926.
The scientist said "Are you positive"
"Uncertainty Principle". He didn't say that the position can't be precisely determined. He said that the position and the momentum can't both be precisely determined at the same time. The more precisely you determine one, the more fuzzy the other becomes at the same time.
When the electrons are at higher energy level,they are said to be excited state.
when an element has 8 electron in outer shell it is said to be inert. inert gases are called noble gases.
You just said it, electrons. The "shell" is just an energy level. It is called a shell because it surrounds the atom, but it is just the electrons. Since there is no way to determine the exact location of an electron, it is referred to as an "electron cloud."
The idea of the path of an electron being unpredictable was presented by Werner Heisenberg. It was "packaged" as "Heisenberg's uncertainty principle" and that's how we know it today. What Heisenberg actually said was that if we look at an electron, the closer we look at its momentum, the less certain we are about its position. And if we look closely at its position, the less certain we can be about its momentum. There is a trade-off when we look for precision, and we cannot have our cake and eat it too. It's one or the other as regards accuracy.
Bohr^ wrong. Werner Heisenberg/ Erwin Shrodinger did.So who did, Bohr or Schrodinger and Heisenberg?

'Said in advance' is what the word 'predicted' means.
That would be the electron cloud. This is like the orbital model where there are electrons in each orbit level but the electron's location can not be predicted so it is said to be most likely at a point in the electron cloud.
professor NEILS BOHR postulated from his discrete electron orbit theory that electrons get caught in imaginary orbits around the atomic nucleus.
The uncertainty principle was developed by Werner Karl Heisenberg.
This electron is called excited.

'Said in advance' is what the word 'predicted' means.
Electrons are said to occupy orbitals, around the atomic nucleus. They do not actually orbit in the manner that planets orbit the sun; they spread themselves out, as an electron cloud, and surround the nucleus rather than moving in an orbit.
