How many elements are naturally occuring?
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
What is the most complex element in the universe?
I am not quite sure what you mean with "most complex"; the element with the highest atomic number that occurs naturally (though only in trace amounts) seems to be Californium (#98), although elements up to #118 have been created artificially.
Why are technetum promethium and neptunium considered naturally occurring elements even though they are not found on earth?
These elements exist also naturally - in infinitesimal amounts - in the Earth crust.But practically are artificial elements.
Is it true that transuranium elements are synthetic elements with atomic numbers greater than 92?
Yes. All elements classified after Element Atomic Number 92 (Uranium) (id est transuranium) are synthesised elements and can not be found naturally. They are also all radioactive, although this is the case for elements from elements 84 onwards.
How many elements are found in the ocean?
98 elements are known to occur naturally on earth. They are probably all found, at least in some minute fraction, in the seas of the world.
There are elements found naturally in the universe?
yes oxygen is an element and it is naturally found in the universe
There are 92 naturally occurring?
There are 92 elements found naturally in the universe.
What is the number of different elements found in the universe?
112

Where is oxygen found in its naturally occurring form?
Oxygen is one of the most abundant elements in our universe. It occurs in our earth's atmosphere, ocean's, and land. Throughout the universe, it is inside stars, planets, and in everything around us.
How many elements are found in the universe?
92
Are there other elements found in stars than hydrogen and helium?
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
What is the most complex element in the universe?
I am not quite sure what you mean with "most complex"; the element with the highest atomic number that occurs naturally (though only in trace amounts) seems to be Californium (#98), although elements up to #118 have been created artificially.
What do elements number 43 61 and 93 to 112 have in common?
They are all man-made or synthetic elements, i.e., they are not found naturally in nature and are atomically unstable.
How do artificial elements differ from naturally occurring elements?
Artificial Elements can only be made by synthesisation in a lab (by firing an atom at a projectile). Wheras natural elements can be found naturally.
Which elements is found in the greatest number of substance?
The most abundant element in the universe is Hydrogen, making up about 75% of all matter.
What atom is found naturally on earth?
Almost every element from hydrogen to uranium (going from smallest to biggest) is found naturally on Earth. Technitium is not found naturally on Earth, it is the exception. The trans-uranic elements are also not found naturally on Earth.
