If the elements are both non-metals, they form a molecular compound. If they are both metals, they form a metallic bonds. If they are a metal and a non-metal they form ionic bonds (salts). (Ammonium salts are non-metals.)
Halogens form salts by combining with metals. Halogens are in the 17th group of the periodic table. Sodium chloride,Potassium iodide are some examples.
Common elements that form salts include metals such as sodium, potassium, and calcium, as well as non-metals such as chlorine, sulfur, and fluorine. Salts are typically formed through the combination of a metal and a non-metal through ionic bonding.
Nonmetals may react with metal to form ionic compounds (salts) or other nonmetal elements to form organic compounds.
The majority of elements, and especially metals form salts.
Metals form salts.
Practically all chemical elements can form salts.
When acids react with bases, they undergo a neutralization reaction to form salts and water. Salts are ionic compounds that result from the combination of a positively charged metal ion from a base with a negatively charged non-metal ion from an acid.
Combining a non-metal oxide with water will typically form an acidic solution. Non-metal oxides, such as sulfur dioxide or carbon dioxide, react with water to produce acids like sulfuric acid or carbonic acid.
Metal Salts + water
Metals and ammonium form generally salts.
Elements that form salts by combining with metals are called halogens. All synthetic elements are radioactive. Elements that lie along the stair step line of the periodic table are metalloids.
