Scientists can directly observe the rate of nuclear decay for all radioactive elements.
Scientists can calculate the half-life of all radioactive elements using the rate of nuclear decay
Explanation:
The true statements from the given options is that "scientists can directly observe the rate of nuclear decay for all radioactive elements" and "scientists can calculate the half-life of all radioactive elements using the rate of nuclear decay".
Let us carefully examine the original statement:
Scientists can directly observe the half-life of all radioactive elements
The keywords from here are:
directly observe
half-life
radioactive elements
to directly observe implies that evaluative information about the half-life is being gathered. In making observations, calculations can be made to make deductions.
half-life is the time taken for half of radioactive nuclei to disintegrate.
Radioactive elements are unstable nuclei that will naturally decay on their own into other nuclei.
It is correct to say that scientist can directly observe the rate of nuclear decay for all radioactive element. The half-life is one of the ways of measuring the rate of decay.
Scientists can calculate the half-life of all radioactive elements using the rate of nuclear decay also.
