A RADIOACTIVE NUCLEUS HAS A HALF-LIFE OF 20 YEARS, STARTING WITH 100,000 PARTICLES, HOW MANY PARTICLES WILL BE LEFT EXACTLY AT THE END OF 40 YEARS
A. 75,000 particles B. 35,000 particles C. 25,000 particles ✓ D. 50,000 particles The answer to the question is: C. 25,000 particles The decay of a radioactive nucleus can be described by its half-life, which is the time it takes for half…
WHICH NOBLE GAS IS RADIOACTIVE AND IS PRODUCED AS A DECAY PRODUCT OF URANIUM AND THORIUM
A. Argon B. Krypton C. Radon ✓ D. Neon The answer to the question is: C. Radon The noble gas that is radioactive and is produced as a decay product of uranium and thorium is radon. Radon is a radioactive noble gas with the…
THE HALF LIFE OF A RADIOACTIVE MATERIAL IS 12 DAYS, CALCULATE THE DECAY CONSTANT
The decay constant, denoted by λ (lambda), is a measure of the rate at which a radioactive substance decays. It is related to the half-life (T1/2) of the substance through the equation: λ = ln(2) / T1/2 Where ln(2) is…
A RADIOACTIVE SUBSTANCE HAS A HALF-LIFE OF 3.8 DAYS, CALCULATE ITS DECAY CONSTANT.
To calculate the decay constant of a radioactive substance, we can use the equation: λ = ln(2) / t½ Where: λ is the decay constant, ln is the natural logarithm function, 2 is the constant representing the ratio of the…
WHAT IS MEANT BY THE HALF LIFE OF A RADIOACTIVE SUBSTANCE
The half-life of a radioactive substance refers to the time it takes for half of the atoms in a sample to undergo radioactive decay. It is a fundamental property of radioactive isotopes and is used to describe the rate at…
