Which two elements occur in a nature as liquid?
Only mercury is a chemical element which occur in the nature as a liquid.
Homogeneous soil and non homogeneous soil?
Homogeneous refers to parts and elements that are the same kind. It can also occur in nature and has common properties, like soil.
How does sodium occur?
Sodium is a very reactive metal. It doles not occur freely in nature. It is found in the form of its salts like sodium chloride, sodium bromide etc
How many elements occur natural?
Elements 1-92 except 43 (technetium) and 61 (promethium) occur naturally. So, there are 90 naturally occurring elements.
How many natural occurring elements are there?
9290, technetium and promethium are radioactive with short halflives, they do not occur naturally.Of the 118 elements that are known, 94 occur naturally. The elements that do not occur on earth naturally, have been produced artificially. Some of the elements that do not occur on earth naturally have been detected in other parts of the universe. See link for more information.Tc and Pm of number 1-92 had not been found naturally until fairly recently, but now they have. Promethium, technetium, neptunium and plutonium are now considered natural chemical elements as trace quantities have been found in nature; consequently, 94 natural chemical elements.We know today there are 118 elements total. So far.94 are considered natural elements as we can add promethium, plutonium and neptunium to natural elements because these elements exist in nature in ultratiny trace quantities.About thirty native elements are known to occur naturally, by themselves, in pure form, uncombined with other elements into minerals. They include metals like copper, gold, lead, and iron; semi-metals like antimony, arsenic, bismuth, and tellurium, and non-metals like diamond, sulfur, and selenium.Some elements decay into other elements very quickly and very little of them remain. However they can be produced in laboratories and during supernova explosions.90, technetium and promethium are radioactive with short halflives, they do not occur naturally.Astatine has an even shorter half life, being furiously radioactive. Make it 89 ?90 elements out of the first 92 elements are naturally occurringThere are 88 naturally-occurring chemical elements90, technetium and promethium are radioactive with short halflives, they do not occur naturally.98
Which of these are elements that occur the most in nature isotopes quarks leptons?
Quarks and leptons are not elements.
Did halogens frequently occur in nature as free elements?
Yes, the halogens did occur in nature as free elements.
What elements occur in nature?
Basically, all (or most) of the elements found in the periodic table, up to plutonium.
How many elements start naturally in nature?
how may elements occur naturally in nature
How do most elements on earth occur?
Most elements on the Earth occur as oxides or silicates.
How did you get the 63 known elements?
There are a lot more than 63 known elements; we are currently up to 118.Most of these elements do occur in nature, and chemists find them in various rocks, in the atmosphere, or in other assorted places. For the elements that don't occur in nature, such as technitium, those are created by the use of particle accelerators.
How many chemicals occur in nature periodic table?
About 80% of the first 117 elements occur in the nature in a stable manner.
How many elements shown in the periodic table do not occur in nature on earth?
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
What form are most elements in nature?
Most elements in nature are found in the solid state.
Is actinoids all transuranium elements?
no. uranium and thorium occur in nature
Why don't these elements occur in nature?
The same reason your mother doesn't.
two elements occur in a nature as liquid?
Only Mercury occurs in nature as a liquid in its elemental state. Bromine is also a liquid element, but does not occur in its elemental form in nature.
