(2 Marks) Ans: Ions are the atoms or a group of atoms in which the number of electrons is not equal to the number of protons. It can be possible to predict whether an atom will form a cation or an anion based on its position on the periodic table. HCl, which contains the anion chloride, is called hydrochloric acid. Due to this potassium bromide is able to be dissolved in polar solvents. A cation is a positively charged ion with fewer electrons than protons while an anion is negatively charged with more electrons than protons . Terms in this set (20) What is an Anion?

Sodium is 2,8,1; Na+ is 2,8. It has the . We interpreted this migration as evidence of 'positive bromine ions' (Br + or H 2 BrO + ions) that were present in these acid solutions. They have an opposite electrical charge, therefore they get attracted to each other. [Pg.52] If phosphorous tribromide is used instead, then the bromine anion will be formed by ionization of Br from PBr3. A cation is an ion that has lost one or more electrons, gaining a positive charge. Cation: K 1+ Magnesium.

Answer to: Write the complete electron configuration for the common monatomic ion formed by the element bromine, Br. Although uncommon, chronic toxicity from bromide can result in bromism, a syndrome with multiple neurological symptoms. The bromine production process is mainly based on the reaction of bromide with chlorine. Chemical Formula lead (IV) ion Pb4+ cation . You can use the charge of the bromide ion to deduce the charge of the copper cation. So in solution you would have lead ions and bromide ions - lead bromide, or you might prefer to call it lead dibromode - (it's not very soluble in water . If the formula is not ionic, then identify how it would be classified. There is a slide with examples about combining cations with anions. Which is larger bromine atom or bromide ion?
