WebNov 20, 2024 · Of the 118 elements listed in the periodic table, only 94 occur naturally. While there are 254 stable isotopes, more than 3,000 radioisotopes are known, of which only about 84 are seen in nature. The radiation emitted is energetic and can be of different types, most often alpha (a), beta (b) and gamma (g).
