This is known as iron-deficiency anemia, the most common type of anemia. Factors that can lower your body's supply of iron include: 1  blood loss (caused by ulcers, some cancers, and other conditions; and, in women, during monthly periods); 2  a diet that doesn't have enough iron in it;3  taking medications that interfere with the ability of the body to absorb iron; blood loss (caused by ulcers, some cancers, and other conditions; and, in women, during monthly periods); 2  a diet that doesn't have enough iron in it; 3  taking medications that interfere with the ability of the body to absorb iron; 4  an increase in the body's need for iron (for instance, in women during pregnancy).
Definition. An anion is an atom or a molecule which is negatively charged, i.e. has more number of electrons than protons. A cation is an atom or a molecule which is positively charged, i.e. has more number of protons than electrons.
In chemistry, a salt is an ionic compound that results from the neutralization reaction of an acid and a base.Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge).he name of a salt starts with the name of the cation (e.g., sodium or ammonium) followed by the name of the anion (e.g., chloride or acetate). Salts are often referred to only by the name of the cation (e.g., sodium salt or ammonium salt) or by the name of the anion (e.g., chloride salt or acetate salt).
