`e//m` ratio of proton is greater than that of electron

The IE of Be is greater than that of B.

When n//p ratio of an isotope is greater than the stable isotope of that element, it emits

(A) : An electron and proton entres a magnetic field with equal velocities, then, the force experienced by proton will be more than electron. (R) : The charge of proton is 1837 times more than the charge of electron.

In response to a question, a student stated that in an atom, the number of protons is greater than the number of neutrons, which in turn is greater than the number of electrons. Do you agree with the statement ? Justify your answer.

Deduce the condition when the De-Broglie wavelength associated with an electron would be equal to that associated with a proton if a proton is 1836 times heavier than an electron.

The mass of a proton is 1847 times that of an electron A electron and a proton are injected into a unifrom electric field at right angle to the direction of the field with the same initial K.E.

Assertion: The electron affinity of chlorine is greater than that of fluorine. Reason: Chlorine is more electronegative than fluorine.

if we assume only gravitational attraction between proton and electron in hydrogen atom and the Bohr quantizaton rule to be followed, then the expression for the ground state energy of the atom will be (the mass of proton is M and that of electron is m.)

The mass of a proton is 1836 times more than the mass of an electron. It a sub-atomic of mass (m) 207 times the mass of electron is captured by the nucleus, then the first ionization potential of H :

Assertion: Mn atom loses ns electrons first during ionisation as compared to (n-1) d electrons Reason: The effective nuclear charge experienced by (n-1) d electrons is greater than that by ns electrons.
