Which statement best explains why a metal atom and a …
Answer: Metal atoms have low ionization energy, and nonmetal atoms have high electronegativity, so electrons transfer easily from the metal atom to the nonmetal atom. Explanation: An ionic bond is formed when an element completely transfers its valence electron to another element.

The metal has a silvery color, is rather hard, and is prepared by electrolysis of fused chloride and calcium fluoride (to lower the melting point). Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame.

Is cesium bromide an ionic or covalent compound? | …
Cesium bromide, "CsBr". is an ionic compound, and can further be classified as a salt Usually a bond between a metal and a nonmetal is ionic. Cesium is a metal and bromine is a nonmetal. In addition, we can look at the difference in electronegativity between the two elements. Electronegativity (EN) is the tendency of an atom to attract electrons to itself. Metals tend to have lower ENs than
Metal | Chemistry | Fandom
In chemistry, a metal is a chemical element whose atoms readily lose electrons to form positive ions, and form metallic bonds between metal atoms and ionic bonds between nonmetal atoms. A metal Alloy is a mixture of two or more elements in a solidified solution. Examples are Steel (Iron+Carbon, Bronze (Copper+Tin), and Electrum (Gold+Silver+::Copper).
Oxide - Nonmetal oxides | Britannica
Oxide - Oxide - Nonmetal oxides: All nonmetals form covalent oxides with oxygen, which react with water to form acids or with bases to form salts. Most nonmetal oxides are acidic and form oxyacids, which in turn yield hydronium ions (H3O+) in aqueous solution. There are two general statements that describe the behaviour of acidic oxides. First, oxides such as sulfur trioxide (SO3) and
