Summary

Description
English: Periodic table with elements colored according to the half-life of their most stable isotope. 32-column format is helpful in showing stability pattern.
 
Elements that contain at least one stable isotope.
 
Radioactive elements: the most stable isotope is very long-lived, with half-life of over four million years.
 
Radioactive elements: the most stable isotope has half-life between 800 and 34.000 years.
 
Radioactive elements: the most stable isotope has half-life between one day and 130 years.
 
Highly radioactive elements: the most stable isotope has half-life between several minutes and one day.
 
Extremely radioactive elements: the most stable isotope has half-life less than several minutes. Very little is known about these elements due to their extreme instability and radioactivity.

Note that this table only addresses the most stable isotope of each element. Therefore it would be erroneous to conclude that all naturally occurring elements from hydrogen through lead are non-radioactive. For example, if you hold a geiger counter up to a banana, you will detect radioactivity because of the potassium isotope 40K, which is also the most common radioisotope in the human body.

Bahasa Indonesia: Tabel periodik dengan unsur-unsur yang diwarnai menurut waktu paruh isotop paling stabilnya. Format 32 kolom sangat membantu dalam menunjukkan pola stabilitas.
 
Unsur yang mengandung setidaknya satu isotop stabil.
 
Unsur radioaktif: isotop paling stabil berumur sangat panjang, dengan waktu paruh lebih dari empat juta tahun.
 
Unsur radioaktif: isotop paling stabil memiliki waktu paruh antara 800 dan 34.000 tahun.
 
Unsur yang sangat radioaktif: isotop yang paling stabil memiliki waktu paruh antara beberapa menit dan satu hari.
 
Highly radioactive elements: the most stable isotope has half-life between several minutes and one day.
 
Unsur yang sangat radioaktif: isotop yang paling stabil memiliki waktu paruh kurang dari beberapa menit. Sangat sedikit yang diketahui tentang unsur-unsur ini karena ketidakstabilan dan radioaktivitasnya yang ekstrem.

Perhatikan bahwa tabel ini hanya membahas isotop paling stabil dari setiap elemen. Oleh karena itu akan keliru untuk menyimpulkan bahwa semua unsur alami dari hidrogen sampai timah adalah non-radioaktif. Misalnya, jika Anda mendekatkan penghitung geiger ke pisang, Anda akan mendeteksi radioaktivitas karena isotop kalium 40K, yang juga merupakan radioisotop paling umum dalam tubuh manusia.
