Question:
The mass of $\alpha$-particle is
The mass of $\alpha$-particle is
Updated On: May 4, 2024
- less than the sum of masses of two protons and two neutrons
- equal to mass of four protons
- equal to mass of four neutrons
- equal to sum of masses of two protons and two neutrons
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
$\alpha$-particle = $_2He^4$. It contains 2 p and 2 n.
As some mass is converted into binding energy, therefore, mass of a particle is slightly less than sum of the masses of 2p and 2n

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Nuclei
In the year 1911, Rutherford discovered the atomic nucleus along with his associates. It is already known that every atom is manufactured of positive charge and mass in the form of a nucleus that is concentrated at the center of the atom. More than 99.9% of the mass of an atom is located in the nucleus. Additionally, the size of the atom is of the order of 10-10 m and that of the nucleus is of the order of 10-15 m.
