Electron cannot be a part of nucleus but protons can be. Why?
Text Solution
AI Generated Solution
To understand why electrons cannot be a part of the nucleus while protons can, we need to analyze the properties of both particles in relation to their wavelengths and the size of the nucleus.
### Step-by-Step Solution:
1. **Understanding the Nucleus**:
The nucleus of an atom is a very small, dense region at the center of the atom, primarily composed of protons and neutrons. The size of the nucleus is typically on the order of \(10^{-15}\) meters (1 femtometer).
2. **De Broglie Wavelength**:
...
Assertion (A) : Nucleus of the atom does not contain electrons, yet it emits beta- particles in the form of electrons. Reason (R): In the nucleus , protons and neutrons exchange mesons frequently.
The electrons cannot exist inside the nucleus because
Light waves can be polarised but sound waves cannot be. Why?
Why electron cannot exist inside the nucleus according to Heisenberg's uncertainty principle?
Assertion (A) : Nucleus of the atom does not contain electrons,yet it ewmits beta -particles in the form electrons Reason (R ) : In the nucleus, protons and neutrons exchange mesons frequently
A positron is emitted by radioactive nucleus of proton no 90 . The product nucleus will have proton number
Assertion(A): An electron cannot exist in the nucleus Reason(R): The deBroglie wavelength of an electron is much smaller than the diameter of the nucleus
A : Uncertainty principle demands that an electron confined to a nucleus must have very high energy so that the electron cannot reside in a nucleus. R: The electrostatic attraction between electron and proton is large at such a small distance but is not enough to bind such a high -energy electron.
Which of the following assertions are correct? (i) A neutron can decay to a proton only inside a nucleus (ii) A proton can change to a neutron only inside a nucleus (iii) An isolated neutron can change into a proton (iv) An isolated proton can change into a neutron
