Radioactive Decay

Question 1

What are the catch when making synthetic elements?

Answer 1

• Synthetic elements are Radioactive
• Synthetic elements are Short lived

Question 2

When an elements is radioactive this means that it is capable of ________ ____________

Answer 2

When an elements is radioactive this means that it is capable of emitting radiation

Question 3

This is energy in the form of electromagnetic waves of fast - moving high - energy subatomic particles

Answer 3

Radiation

Question 4

All elements having an atomic number greater than _____ are __________, but not all of them are ____________

Answer 4

All elements having an atomic number greater than 83 are radioactive but not all of them are synthetic

Question 5

This is spontaneous release of radiation due to nuclear instability

Answer 5

Radioactive decay

Question 6

This transform into more stable and lighter elements when they decay

Answer 6

Radioactive elements

Question 7

How do we know if an element/isotope is already stable?

Answer 7

• Elements/ Isotopes can progressively undergo radioactive decay so long as the daughter element /isotope created Is still unstable

• An element / Isotope will become stable if the ratio of it’s protons and neutrons are within the so called band of stability
