Answer: The statement is true
Explanation:
The half-life of a radioactive isotope is the time taken for half of the total number of atoms in a given sample of the isotope to decay.
For instance
The half-life of radium is 1622 years. This means that if we have 1000 radium atoms at the beginning, then at the end of 1622 years, 500 atoms would have disintegrated, leaving 500 undecayed radium atoms
Thus, the statement is true
Mainly around the equator, since it receives the most direct sunlight year round.
Answer:
The answer option which best describes nuclear fission is: C. A nucleus collides with a neutron and splits, releasing energy.
A nuclear reaction can be defined as a type of reaction in which the nucleus of an atom is transformed by either being joined (fusion) or split (fission) with the nucleus of another atom of a radioactive element and accompanied by a release of energy.
