What elements Cannot be made?
Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P4) or sulfur (S8) cannot be broken down into simpler substances by these reactions. Example: Water decomposes into a mixture of hydrogen and oxygen when an electric current is passed through the liquid.

Are Everything made of elements?
All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions. Gold, for instance, is an element, and so is carbon.
Is Tin an element?
tin (Sn), a chemical element belonging to the carbon family, Group 14 (IVa) of the periodic table. It is a soft, silvery white metal with a bluish tinge, known to the ancients in bronze, an alloy with copper.
Which is the not an element?
Answer: (3)silica Graphite is a carbon element. Silicon(Si) and germanium(Ge) are also elements, but silica (SiO2) is not an element.
What are the non neutral elements?
Atoms that are not electrically neutral are called ions and examples of atoms frequently found in their ionic for include sodium, chlorine and magnesium.
Is aluminum an element?

What were the 4 original elements?
The Four Elements. Greek philosophy supposed the Universe to comprise four elements: Fire, Water, Earth, and Air. Air was originally supposed to be a component of the Æther [ether, not to be confused with the gas], the element that filled the Universe in the absence of the other three.

What is unsourced material?
Unsourced material may be challenged and removed. This list contains fictional chemical elements, materials, isotopes or subatomic particles that either a) play a major role in a notable work of fiction, b) are common to several unrelated works, or c) are discussed in detail by independent sources.
What is the fundamental component of matter according to Crookes?
In 1886 Crookes suggested that the fundamental component of matter was something like Prout’s proto hyle (also known as protyle) which generated the heavier elements by an evolutionary process while cooling from stellar to terrestrial temperatures.
What are the man-made synthetic elements?
A Complete List of Man-made Synthetic Elements. Technetium (atomic number 43) was the first synthetic element discovered, that filled the mysterious gap between the elements, Molybdenum (atomic weight 42) and Ruthenium (atomic weight 44) in the periodic table. Promethium (atomic number 61), Astatine (atomic number 85),…
