Some isotopes are radioactive and decay into other elements upon radiating an alpha or beta particle.
All the heavier elements are made naturally and artificially through various methods of nucleosynthesis.
The naming of elements precedes the atomic theory of matter, although at the time it was not known which chemicals were elements and which compounds.
Nonelements, especially in organic and organometallic chemistry, often acquire symbols that are inspired by the elemental symbols.
The periodic table itself shows two main types of elements, metals and non-metals.
All artificially derived elements are radioactive with short half-lives so that any such atoms that were present at the formation of Earth are extremely likely to have already decayed.
The most convenient presentation of the elements is in the periodic table, which groups elements with similar chemical properties together.
When it was learned, existing names (e.g., gold, mercury, iron) were kept in most countries, and national differences emerged over the names of elements either for convenience, linguistic niceties, or nationalism.
Elements are usually divided into three types; metals, non-metals, and metalloids.
The elements and their periodic physical and chemical properties are catalogued in the Periodic table.
Precursors of such controversies involved the nationalistic naming of elements in the late nineteenth century (e.g.
In Astrology, there are four fundamental elements, which are:Fire (Aries, Leo, Sagittarius)Earth (Capricorn, Taurus, Virgo)Air (Gemini, Aquarius, Libra)Water ( Pisces, Cancer, Scorpio)
The supernatural is defined as events or things that cannot be explained by nature or science and that are assumed to come from beyond or to originate from otherworldly forces. Ghosts and witches are an example of the supernatural.
According to current models, in addition to large amounts of iron, the Earth's liquid outer core contains small amounts of so-called light elements, possibly sulfur, oxygen, silicon, carbon, or hydrogen.Nov 23, 2011
