The video discusses isotopes, focusing on those that do not decay radioactively or have long half-lives. These stable isotopes are often used in various applications due to their stability over time.

What is the primary focus when discussing isotopes in the long term?

• Their ability to change color

• Their stability over time

• Their magnetic properties

• Their electrical conductivity

Which isotopes are typically used due to their non-radioactive nature?

• Isotopes that are highly reactive

• Isotopes with long half-lives

• Isotopes with short half-lives

• Isotopes that decay quickly

What is a key characteristic of isotopes that do not decay radioactively?

• They emit high levels of radiation

• They have short half-lives

• They are stable over long periods

• They are highly reactive

Why are isotopes with long half-lives often applied?

• They are less expensive

• They are easier to detect

• They are more stable

• They are more colorful

In what context are stable isotopes usually applied?

• In short-term experiments

• In high-temperature environments

• In low-pressure conditions

• In long-term studies
