Where is there zero probability of finding an electron in an atom?

Electrons can be described as waves and the laws of quantum mechanics determine them and their location probabilistically or statistically. Applying these laws, electrons are distributed in orbitals around the nucleus of the atom according to how much energy they have with higher energies being more distant from the nucleus. The different orbitals have different shapes. The equations say that there are "nodes" where the probability is zero and again these nodes differ for the different orbitals and energies. One of the mind blowing things about quantum mechanics is that electrons can only be at certain discrete energies and orbitals and therefore must be able to go from one to the other without ever passing in between. As the great Richard Feynmann said, if you think you understand quantum mechanics, then you don't really understand quantum mechanics. But the math works and the theory is the most precise and proven theory in the history of science.

Explain why the overall or net charge on an atom is zero?
because the charge of two protons and two neutrons and two electrons it = 0yes all atoms have a net charge of zerothere is an equal amount of electrons and proton, which have an equal but opposite charge.
What are the differences between a proton and an electron?
a proton is a part of the atom, more specifically the nucleus (which also contains neutrons) and the electron is an even smaller particle that rotates around the nucleus of the atom and has a mass so minuscule even to an atom it is generally given the weight of zero.
A certain oxygen atom has the electron configuration 1s2 2s2 2px2 2py2 How many unpaired electrons are present?
Zero
What particle in the atom is the least massive?
least - electron most - the top quark
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.
What is node and nodal plane?
It is the portion in an atom outside the nucleus where the probability of finding an electron is zero.
What name is given to a region of an electron probability density graph where the probability of finding the electron is zero?
The region of zero electron density is called a "node."
Why electrons don't attract with protons inside an atom?
They do attract, but they will not collide because the probability of finding an electron in the nucleus approaches zero as the distance from the nucleus approaches zero.
What is the probability of finding an electron at a node?
Not zero, but very, very, very, very............ close to zero. ---- Actually, the probability function for s orbitals has a local maximum at the nucleus (though it does assume that electrons and nuclei are dimensionless points). I honestly can't recall ever seeing any discussion on how the fact that they are not really dimensionless points affects the probability function, but still, for an s electron, a point "just outside" the nucleus has a significantly higher probability than a point a Bohr radius away does.

How many negatives positives and neutrals do a hydrogen atom have?
A hydrogen atom has one proton, one electron, and zero neutrons.
What is the subatomic particle with a mass number of zero and a charge of -1?
In the atom a proton has the charge +1 and the electron the charge -1.
How does a particle tunnels through a barrier?
In a purely classical world, the probability of a moving particle getting through an electro-static barrier was simple: if the kinetic energy of the particle was greater than the charge times the voltage, it was 100% likely to get through, if the KE was less, the probability was zero. In the latter case, the ball would simply bounce back, because the energy level of the voltage barrier ( 'E(vb)' ) was simply too large for that particle's KE to overcome When you do the mathematics of the Schroendinger Equation with this situation -- a charged particle meeting a voltage barrier -- you can no longer talk about what WILL happen with 100% certainty. You can only discuss the PROBABILITY of something happening. For example, even if the electron has more KE than E(bv), then there is some chance that it will bounce back. When a moving electron meets a voltage barrier, in which the initial KE is smaller than E(vb), then the probability of finding that electron in that barrier goes down fairly rapidly. If the barrier is thick, then the probability of finding the electron in that area of high voltage goes down to zero. On the other hand, it CAN happen that, for a thin barrier (or a fast electron or a voltage barrier not too large), that the probability of finding an electron beyond the barrier does NOT go down to zero. In that case, you have quantum tunnelling. The mathematics are fairly complicated; but have been shown to agree with experiment.
How many electrons does one hydrogen atom have in its outer shell?
Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.
What are the differences between a proton and an electron?
a proton is a part of the atom, more specifically the nucleus (which also contains neutrons) and the electron is an even smaller particle that rotates around the nucleus of the atom and has a mass so minuscule even to an atom it is generally given the weight of zero.
