Does measuring the momentum of the electron around the nucleus cause it to behave as a particle and so the cloud disappears as shown in double slots experiment?

Well, the act of measuring an electron's momentum changes its position, rendering the measurement invalid. This is the Heisenberg Uncertainty Principle.

What is the angular momentum of an electron in 2s-orbital?
Zero.
How magnetic moment of electron is associated with angular momentum of electron?
magnetic moment of a particle is due to its motion around some other orbits or about its own orbit i.e due to its orbital angular momentum or its spin angular momentum.
Why does the concept of Bohr orbits violate the uncertainty principle?
The Bohr Model of a single-electron atom assumes that the energy levels of electron orbits are fixed due to the quantization of angular momentum of the electron while in orbit. The problem occurs because angular momentum depends on both the radius of the orbit and the velocity of the electron in that orbit. If one or the other is uncertain, then it is impossible to know the angular momentum. Heisenberg showed that either one or the other MUST be uncertain. If we are certain about the radius, we MUST have uncertainty about the velocity -- and vice-versa. Thus, angular momentum of an orbting electron can NOT be quantized, because it can not be known.
Do electrons travel so fast that it is impossible to know their exact location?
No, that's not how it works. The Heisenberg Uncertainty Principle states that there is a limit to how precisely you can measure position and momentum simultaneously. Actually, it's not just about measuring, position and momentum are not DEFINED at the same time, with arbitrary precision.An electron can very well move slowly, but the Uncertainty Principle still applies.
a proton and electron have the same kinetic energywhich has longer wavelength?
the electron would have the longer wavelength b/c the proton has more momentum and λ=h/p (λ is wavelength, h is planc's constant and p is momentum)
Does an object have to be heavy in order to have momentum?
No. Even a single electron has momentum.
When is the mass of an electron regarded as zero?
The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.
If an electron and a proton have the same momentum which has the higher speed?
The electron, because it has much less mass than the proton and momentum is the product of mass and speed.
Does directions matter when you are measuring momentum?
Yes, momentum is a vector variable and direction matters in vectors.
Why do the electrons that orbit the nucleus of an atom never lose momentum?
electrons that orbit the nucleus of an atom never lose momentum because of the CENTREPETAL FORCE afford by the moving electron. In our Universe, when you get to things the size of an atom, the rules for how things operate changes from what we are used to. For starters, you can no longer say that an electron acutually HAS a momentum or even a position. Instead, you can only state (1) the probability that an electron has a specific momentum or position and (2) the AVERAGE momentum or position of an electron. And it is NOT the case that we lack the ability to measure these things, or that the electron "knows" these things but we don't -- the momentum and position of electrons are inherently UN-KNOWABLE, even to the electron itself! Thus, we can not say an electron "loses" its momentum over time, because we can't even say what its momentum IS. And we can't do so because the ELECTRON ITSELF doesn't "know" its own momentum! Confusing? Don't like this? Sorry -- that's how our Universe operates.

Is any electron different from any other electron?
No. The properties of one electron will be the exact same as any electron anywhere else in the universe, barring momentum.
Quantum mechanics can be used to calculate the probability of an electron's what at any given time?
An electron's location or momentum, but not both.
How did momentum and impulse affects the egg drop experiment?
Thats for me to know and you to find out.

What is the spin-helix state?
The momentum independent eigenstate defined for a twodimensional electron gas withlinear in momentum Bychkov-Rashba and Dresselhaus type spin-orbit interaction of equal magnitude. In momentum space this state is characterized by a +pi/4 or -pi/4spin orientation in the plane of the electron gas.
