The half-life of a given isotope is theoretically considered constant. This means that after each half-life period, the amount of the radioactive isotope will reduce to half its initial value, consistently, regardless of the amount of substance present. Each half-life period is the same duration, which is a characteristic of the isotope.
However, it's important to note that while the half-life is constant for a specific isotope under stable conditions, external factors such as changes in temperature, pressure, or chemical state do not affect the half-life itself. Therefore, for practical purposes and standard conditions, the half-life can be treated as constant.
In summary, the answer is: **Theoretically, yes it is constant and it splits in half every half-life.**
