All metals have metallic bonds; also generally metals are more hard than nonmetals, with higher melting and boiling points, with better thermal and electrical conductivities etc.
It is the calcium atom. It has all the properties of calcium.IT is a metal element.
Cobalt is known as a metal because it is a chemical element with metallic properties. It has luster, conductivity, and typically forms cations in solution. Cobalt is classified as a transition metal due to its position in the periodic table.
Mercury is a metal , with all the properties of a metal except it is a liquid at room temperature.for ex when we use a thermometer we found mercury in liquid form. it is a metal
All these elements are metal. They have same properties.
- all metal salts are ionic compounds - many salts are soluble in water and are dissociated
Non-metal
magnesium is not a metal but a reactive metal. scientists have divided all elements into two types of category: metals and non-metals to classify them as they have different chemical and physical properties. magnesium has properties of a metal so it is a metal.
Mercury? its a liquid metal It has metal properties and liquid properties right? someone let me know.
Non-metal
Alloys can help neutralize unwanted properties of a metal
Actinium is a metal because has metallic bonds and the properties of a metal.
Neither it is a metalloid or semi-metal. It has both metallic and nonmetallic properties.
