Protons neutrons and electrons. Technetium Tc and promethium Pm are man-made elements and do not have. 6 How many element do we have.

However it turns out there are other elements that occur in trace amounts naturally. The periodic table lists all these combinations. Out of the first 92 elements 1 being hydrogen H and 92 being uranium U there are 90 that are naturally occurring.

How Many Elements Occur Naturally On Earth92Are there 94 of 92 naturally occurring elementsSo the grand total of natural elements is 94 or 98. The periodic table is a model that illustrates the properties of elements and also how they interact with each other. 1 proton and 1 electron is a Hydrogen atom 2 protons 2 neutrons and 2 electrons is a Helium atom and so forth.

Solve any question of Classification Of Elements And Periodicity In Properties with-. 5 Which atoms represent different isotopes of the same element. 9 What are the different types of elements.

It is difficult to give an exact accounting but the usual answer is that all elements 192 EXCEPT elements 64 and 82 Tc and PM are naturally occurring but there are some elements not on this list which have been reported especially Np. The usual textbook answer is 91. The elements are listed in order of importance or order of discovery on the periodic table.

8 How many different elements are represented in the compound fe3o4. If you Google it most links say that the naturally-occurring elements are 1 - 92 with the exception of 43 technetium and 61 promethium. Values in brackets.
