What type of ions does the following elements form.- Chlorine, Sodium, Sulphur, Potassium, Aluminium, Oxygen, Nitrogen and Magnesium.
Answers
Answer:
The chloride ion /ˈklɔːraɪd/ is the anion (negatively charged ion) Cl−. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water. Conjugate acid: Hydrogen chloride
Chemical formula: Cl−
Sodium(1+) is a monoatomic monocation obtained from sodium. It has a role as a human metabolite and a cofactor. It is an alkali metal cation, an elemental sodium, a monovalent inorganic cation and a monoatomic monocation.
When sulfur reacts with an active metal, it can form the sulfide ion, S2-. This is not the only product that can be obtained, however. A variety of polysulfide ions with a charge of -2 can be produced that differ in the number of sulfur atoms in the chain.
Potassium(1+) is a monoatomic monocation obtained from potassium. It has a role as a human metabolite and a cofactor. It is an alkali metal cation, an elemental potassium, a monovalent inorganic cation and a monoatomic monocation.
It would tend to gain one electron and form a -1 ion. Aluminum is in the fifth column and therefore has 5 electrons in its outermost shell. It would tend to lose three electrons and form a +3 ion
Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-.
Nitrogen also has a family of oxyanions. The two in this group are the nitrate ion, NO−3, and the nitrite ion, NO−2. Either of these can form acids or ionic compounds, much like nitride ions.
Magnesium, Mg
Magnesium is in Group 2. It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2+, is formed. A magnesium ion has the same electronic structure as a neon atom (Ne).
It is a bit long but I hope it helps you
