element (redirected from formed e's (of the blood))

element /el·e·ment/ (el´ĕ-ment)

1. any of the primary parts or constituents of a thing.

2. in chemistry, a simple substance that cannot be decomposed by chemical means and that is made up of atoms which are alike in their peripheral electronic configurations and so in their chemical properties and also in the number of protons in their nuclei, but which may differ in the number of neutrons in their nuclei and so in their mass number and in their radioactive properties.

3. in the philosophies underlying some complementary medicine systems, a member of a group of basic substances that give rise to everything that exists.

element

Etymology: L, elementum, first principle

one of more than 100 primary, simple substances that cannot be broken down by chemical means into any other substance. Each atom of any element contains a specific number of protons in the nucleus and an equal number of electrons outside the nucleus. In most elements, the nucleus may contain a variable number (high or low) of neutrons. An element with a disproportionate number of neutrons may be unstable, in which case the nucleus undergoes radioactive decay into a more stable element. See also atom, compound, molecule, radioactivity.

element,

n a simple substance that cannot be decomposed by chemical means and is made up of atoms that are alike in their peripheral electronic configuration and chemical properties but differ in their nuclei, atomic weights, and radioactive properties.

element

1. any of the primary parts or constituents of a thing.

2. in chemistry, a simple substance that cannot be decomposed by ordinary chemical means; the basic 'stuff' of which all matter is composed.

Chemical elements are made up of atoms. Each atom consists of a nucleus with a cloud of negatively charged particles (electrons) revolving around it. The two major components of the nucleus are protons and neutrons. The number of protons in the atoms of a particular element is always the same, and therefore the physical and chemical properties of the element are always the same. It is possible, however, for a chemical element to exist in several different forms, the difference depending on the number of neutrons in the nucleus of its atoms. Different forms of the same element are called isotopes.

There are at least 105 different chemical elements known. Table 6 lists 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 an atom of the element. The mass number of an isotope is determined by the total number of neutrons and protons in the nucleus.

Patient discussion about formed e's (of the blood).

Q. what consider to be a good nutrition for children? does it has to include some specific nutrition elements?

A. there's many things you should consider about children's nutrition, the amount of books written about kids nutrition can fill a library...
vitamins, organic vs industrial, fast food vs home made etc.
here are 2 video libraries that i'm sure you'll find all the info you seek in them-
