When the first element is a metal What do you have to do to determine the formula?

The first element in the name is a metal if the compound is ionic. The first element is a cation and the second is an anion. If that element is to the left of the stairstep line on the periodic table, you can tell that the compound is ionic. When two or more nonmetals share electrons.

Which element is always written first in an ionic compound the metal or the non metal element?

When naming binary ionic compounds, name the cation first (specifying the charge, if necessary), then the nonmetal anion (element stem + -ide).

When naming a compound What ending do you use for the anion if it is a monatomic ion?

Monatomic anions are named by taking the root of the element name and applying an -ide ending. Other important simple anions. Monatomic anions do not occur with multiple charges, thus each nonmetal can form only one monatomic anion, unlike some of the metals which can have multiple monatomic cations.

How are anions used?

Anions are negatively charged ions, and are formed from atoms or molecules that have more electrons than protons. Anions often combine with cations to make salts, which are important in the human body. These particles play a role in many vital biological processes, from hormone production to DNA formation.

How is anion gap treated?

Treatment is directed at reversing the underlying cause. Hemodialysis is required for renal failure and sometimes for ethylene glycol, methanol and salicylate poisoning. When metabolic acidosis results from loss of bicarbonate, as in normal anion gap acidosis, bicarbonate therapy is usually safe and effective.

How do you fix anion gap?

  1. Anion gap may be underesitmated in hypoalbuminaemia, because if albumin decreased by 1g/L then the anion gap decreases by 0.25 mmol.
  2. To overcome the effects of the hypoalbuminaemia on the AG, the corrected AG can be used which is AG + (0.25 X (40-albumin) expressed in g/L.

What causes increased anion gap?

Theoretically, raised anion gap can result from either a decrease in unmeasured cations or an increase in unmeasured anions. In practice it is almost exclusively the result of increased unmeasured anions derived from metabolic acids. Metabolic acidosis is thus the most common cause of raised anion gap.
