Chemical element A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, Z). There are 118 elements that have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements.

- A chemical element or element is a chemical substance consisting of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, Z).he standard state, also known as reference state, of an element is defined as its thermodynamically most stable state at 1 bar at a given temperature (typically at 298.15 K). In thermochemistry, an element is defined to have an enthalpy of formation of zero in its standard state.

- An element is something basic and important––in chemistry, an element is one of the essential molecules that everything else is made of. If a book's ending carries and element of surprise, it means surprise is an important part of the story's end. One of the earliest meanings of this noun was in reference to any of four substances, earth, air, fire, or water, that were formerly regarded as a basic constituent of the universe.

element A substance composed of atoms of only one kind, i.e., of identical atomic (proton) number, which therefore cannot be decomposed into two or more elements, and which can lose its chemical properties only by union with some other element or by a nuclear reaction changing the proton number.See Appendix 6 for a list of the elements, and the symbol, atomic weight, and atomic number of each.) The atomic number of an element is determined by the number of protons in the nucleus of one of its atoms. The mass number of an isotope is determined by the total number of neutrons and protons in the nucleus.

- A chemical element or element is a chemical substance consisting of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, Z).he properties of the chemical elements are often summarized using the periodic table, which powerfully and elegantly organizes the elements by increasing atomic number into rows (periods) in which the columns (groups) share recurring (periodic) physical and chemical properties.

How do I figure out my cost basis on a stock investment? The cost basis of the investment is $10,000, but it is more often expressed in terms of a per share basis, so for this investment it would be $10 ($10,000/1,000). After a year has passed, the value of the investment has risen to $15 per share, and you decide to sell.: The cost basis of any investment is the original value of an asset adjusted for stock splits, dividends and capital distributions.
