How many elements are naturally occuring?
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
How many known elements are there on earth are naturally made?
There are 92 naturally occurring elements on Earth.
Most of the naturally occurring elements are?
Most of the naturally occurring elements are metals. These elements are found in the Earth's crust and have various physical and chemical properties. Some examples of naturally occurring metals include iron, copper, and gold.
What are the 4 naturally liquid elements?
The four elements that are naturally liquid at room temperature are: mercury, bromine, francium, and cesium. Mercury and bromine are the most common naturally occurring liquid elements.
What is unique about the first 92 elements?
90 of them are naturally occurring on earth. The other 2, technetium and promethium, must be manufactured in reactors or accelerators and are very radioactive. Elements beyond bismuth in the periodic table are all radioactive. This leaves a total of 81 natural non radioactive elements. Element 92, the last, is the only one to have a naturally occurring fissile isotope, Uranium-235, that can be used to power reactors or build fission bombs.That probably wasn't the answer you wanted.
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.

What are element that are not naturally occurring elements called?
Synthetic
Were the first 28 elements naturally occurring?
Yes
Are the most naturally occurring elements metals?
No, the most naturally occurring elements are not all metals. The majority of elements on the periodic table are metals, but non-metal elements also occur naturally. Examples of non-metals include oxygen, nitrogen, and carbon.
Most of the naturally occurring elements are?
Most of the naturally occurring elements are metals. These elements are found in the Earth's crust and have various physical and chemical properties. Some examples of naturally occurring metals include iron, copper, and gold.
How many naturally occurring atoms exist?
There are 92 naturally occurring elements, with a total of 118 naturally occurring elements in the periodic table. Each element is composed of atoms with a specific number of protons in the nucleus that determines its identity.
How many chemical elements occur naturaly in the universe?
There are 94 naturally occurring chemical elements in the universe. These elements range from hydrogen, the most abundant, to uranium, the heaviest naturally occurring element.
How many electrons does the heaviest naturally occurring element have?
Uranium, number 92 is the last of the naturally occurring elements and, of course, it has 92 electrons.
What are two types of elements from or in the periodic table?
Naturally occurring and man made elements
