An element can be created in a particle accelerator or fusion reactor. It can also be "made" by waiting out the half-life of an element further down on the Periodic Table.
Elements can occur in nature as pure substances, such as oxygen or gold, or as compounds when they combine with other elements to form molecules like water or carbon dioxide. Elements can be found in various forms, including solids, liquids, and gases, depending on their properties and conditions in the environment.

Name 2 ways nature can cool a large mass of air?
Nature can cool a large mass of air through adiabatic cooling, where air rises and expands at higher altitudes, causing it to cool down. Additionally, evaporative cooling can occur when moisture in the air evaporates, absorbing heat energy and thus cooling the air.
How many elements are present in NI3?
There are 4 elements present in NI3: nitrogen (N) and iodine (I) each occur 1 time, resulting in a total of 2 atoms, and there are 3 molecules of iodine in NI3.
How many elements are in the compound Fe2O3 what are they?
There are two elements in the compound Fe2O3. These are: iron and oxygen
What group does the alkaline earth metals belong to?
Alkaline earth metals belong to Group 2 of the periodic table, which consists of beryllium, magnesium, calcium, strontium, barium, and radium. They are known for their high reactivity and are commonly found in nature as compounds rather than pure elements.
Why doesn't calcium occur free in nature?
Calcium is a reactive element and tends to readily form compounds with other elements, such as oxygen and carbon. In nature, calcium is commonly found as various minerals, like calcium carbonate in limestone and calcium sulfate in gypsum. This mineral form allows calcium to be more stable and less reactive compared to its free elemental state.
Why group 1 and group 2 elements do not occur free in nature?
Group 1 and Group 2 elements are highly reactive and easily lose electrons to form stable compounds with other elements. This reactivity makes them unlikely to exist freely in nature. They quickly react with other elements to achieve a stable electron configuration.
What are the 2 ways that respiration can occur in animals?
Aerobic and anaerobic
How many elements cant be found in nature?
Uranium, element number 92, is the largest naturally occurring element. However, francium, 87, and astatine, 85, along with any element with an atomic number larger than 92 are not found in nature. They are produced in the laboratory. If they do occur naturally they are in exceedingly small quantities. So to answer your question "How many elements can't be found in nature?" about 16 or a few more.
Are all 109 known elements found in nature?
There are 92 "natural elements, and 21 manmade elements, for a total of 113 elements - all of which exists on earth. You probably learned there are 108 elements, but in the past 2 decades, they have discovered (or made) 5 more. This only means that you probably went to highschool in the early 90s like me.
75 percent of the elements on the periodic table are what?
Most of the elements in the periodic table of elements are metals. Also, most of them are made by nature. Elements with the atomic number of 1-91 are made by nature. Elements with the atomic number of 92-118 are man-made.
What are 2 ways a chemical reaction can occur?
Succesfully and unsuccessfully are two typical methods.
How many elements occur in each of the first three periods or the periodic table?
The first period of the periodic table has 2 elements, the second period has 8 elements, and the third period has 8 elements as well.
How many possible outcomes are from tossing two cubes labelled 1 through 6?
As each cube can land with 1 of 6 faces on top there are 6 × 6 = 36 possible outcomes If the numbers displayed on the top faces are added together then there are 11 possible outcomes: 2, 3, 4, ..., 11, though they do not all occur with the same frequency: 2 can only occur when both cubes show a 1 3 can occur when one shows a 1 and the other shows a 2 4 can occur when one shows a 1 and the other shows a 3, or they both show a 2 and so on. The number of ways the sums can occur is: 2 - 1 way 3 - 2 ways 4 - 3 ways 5 - 4 ways 6 - 5 ways 7 - 6 ways 8 - 5 ways 9 - 4 ways 10 - 3 ways 11 - 2 ways 12 - 1 way 1 + 2 + 3 + 4 + 5 + 6 + 5 + 4 + 3 + 2 + 1 = 36 - all the possible outcomes of throwing the two cubes.
What are 2 ways that nature and geography are shaped?
Nature and geography are shaped by the movement of tectonic plates and weather (wind, rain & ice mostly).
Name 2 ways nature can cool a large mass of air?
Nature can cool a large mass of air through adiabatic cooling, where air rises and expands at higher altitudes, causing it to cool down. Additionally, evaporative cooling can occur when moisture in the air evaporates, absorbing heat energy and thus cooling the air.
What are the five ways to prepare salts?
1. From the elements. 2. From a reaction between an acid and a base.
What are the four ways evolution?
These four factors can effect ways evolution occur: 1.) Mutation 2.) Selection3.) Gene Flow4.) Genetic Drift
