Among the discovered elements _______ elements are found in nature
Answers
Answer:
The elements found in nature are elements with atomic numbers 1 (hydrogen) through 98 (californium). Ten of these elements occur in trace amounts: technetium (No. 43), promethium (61), astatine (85), francium (87), neptunium (93), plutonium (94), americium (95), curium (96), berkelium (97), and californium (98)
Answer:
some elements have been made by man, but do not exist naturally. Have you ever wondered how many elements are found in nature?
Of the 118 elements that have been discovered, there are 90 elements that occur in nature in appreciable amounts. Depending who you ask, there are another 4 or 8 elements that occur in nature as a result of radioactive decay of heavier elements. So, the grand total of natural elements is 94 or 98. As new decay schemes are discovered, it's likely the number of natural elements will grow. However, these elements will likely be present in trace amounts.
