What Are Elements Made up Of?
rows · This is a list of the chemical elements which have been identified as of A chemical. Aug 05, · Elements are made of atoms, which are particles that represent the most basic form of an element. An atom is the smallest particle of an element and cannot be further divided without becoming a less complex particle; in fact, the word 'atom' comes from the Greek word "atomos," meaning 'indivisible'. An atom consists of a nucleus containing protons and neutrons surrounded by a cloud of electrons.
Our world is made of elements and combinations of elements called compounds. An element is a pure substance made of atoms that are elemdnts of the same type. At present, elements are known, and only about 90 of these occur naturally. As the cloud of cosmic dust and gases from or Big Bang cooled, stars formed, and these then grouped together to form galaxies.
The other whta elements found in nature were created in nuclear reactions in these stars and in huge stellar explosions known as supernovae.
For most of their lives, stars fuse elemental hydrogen into helium in their cores. Two atoms of hydrogen are arw in a series of steps to create helium The energy from these nuclear reactions is emitted in various forms of radiation such as ultraviolet light, X-rays, visible light, infrared rays, microwaves and radio waves. In addition, energised particles such as neutrinos and protons are released, and it is these that make up the solar wind.
Earth is in the path of this energy stream, which warms the planet, drives weather and provides energy for life. The dying star expands into al red giant, and this now begins to manufacture carbon atoms by fusing helium atoms.
More massive stars begin a further series of nuclear burning or reaction what are all elements made of. The elements formed in these stages range from oxygen through to iron.
During a supernova, the star releases very large amounts of energy as well as neutrons, which wnat elements heavier than iron, such as ot and gold, to be produced. In the supernova explosion, all of these elements are expelled out into space. Our world is literally made up of elements formed deep within the cores of stars now long dead.
Examples of element making nucleogenesis in helium burning reactions:. The answer is to be found in the development of nuclear power plants and machines known as particle accelerators:. One of the habits of scientists is open-mindedness. Scientists need to be receptive to new ideas and suggestions.
As new evidence is discovered, new ways of interpreting and understanding it may have to be considered. Find out more about more about what an element is on Biology Online. Read our latest newsletter online here. Nature of science One of the habits of scientists is open-mindedness.

Elements and the ‘Big Bang’ theory
This is a list of the chemical elements which have been identified as of A chemical element, often simply called an element, is a species of atoms which all have the same number of protons in their atomic nuclei i. A popular visualization of all elements is the periodic table of the elements , a convenient tabular arrangement of the elements by their chemical properties that uses abbreviated chemical symbols in place of full element names, but the simpler list format presented here may also be useful.
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight , density , and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies. From Wikipedia, the free encyclopedia. A list of the identified chemical elements.
Helium can only solidify at pressures above 25 atmospheres, which corresponds to a melting point of 0. The actual value may differ depending on the isotopic composition of the sample. Since , IUPAC provides the standard atomic-weight values for these elements using the interval notation. The corresponding standard atomic weights are: Hydrogen: [1. However, four such elements, bismuth, thorium, protactinium, and uranium, have characteristic terrestrial isotopic compositions, and thus their standard atomic weights are given.
