What is the mass number of an atom with 17 protons and 18 neutrons?
Calculate the radius of ⁸₄Be nucleus. Given r₀ = 1.2 × 10⁻¹⁵ m.
What is the binding energy equivalent of 1 atomic mass unit (u)?
A radioactive sample has 1000 atoms initially. After one half-life, how many atoms remain?
Sample Questions
Which of the following are characteristics of α-particles? (Select all correct answers)
Show answer
They are helium nuclei, They have high ionizing power, They consist of 2 protons and 2 neutrons
α-particles are helium nuclei (⁴₂He) with 2 protons and 2 neutrons, making them positively charged. They have high ionizing power but low penetrating power, being stopped by thin aluminum sheets.
The half-life of a radioactive substance is directly proportional to its decay constant.
Show answer
False
Half-life is inversely proportional to decay constant: T₁/₂ = 0.693/λ. As decay constant increases, half-life decreases.
In the nuclear reaction ¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H, what is conserved?
Show answer
Mass number, Atomic number, Charge, Energy
In nuclear reactions: Mass number (14+4=17+1=18), Atomic number (7+2=8+1=9), and Charge are conserved. Energy is also conserved. Number of neutrons may change.
Nuclear fission of ²³⁵U typically releases how much energy per fission?
Show answer
200 MeV
Nuclear fission of ²³⁵U releases approximately 200 MeV per fission event. This enormous energy comes from the mass defect when uranium splits into lighter fragments.
