Density at room temperature is 1.738 g/cm3.
Melting point is 650 °C.
Boiling point is 1091 °C.
Calcium has similar physical and chemical properties to magnesium and strontium. They all belong to the same group of the periodic table, which means they have similar reactivity and characteristics.
The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.
Chemical properties involve reacting with another substance. IE: burning of magnesium requires oxygen after which it is no longer magnesium. Physical properties do not. IE: metals are malleable, some very malleable, like copper wire can be bent with your hand. BUT it is still copper wire.
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.
Magnesium belongs to the family of alkaline earth metals in the periodic table. It exhibits physical properties such as high strength-to-weight ratio, low density, and strong alkaline reactivity.
When magnesium wire is heated, it undergoes several physical changes. Initially, it expands due to increased temperature, which causes the atoms to vibrate more vigorously. As the temperature rises further, magnesium can ignite and burn with a bright white flame, producing magnesium oxide. This combustion alters its physical state, transforming the wire into a powdery ash-like residue.
Burning a magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This results in a new substance being formed with different chemical properties than the original magnesium ribbon.
Calcium is the element that has the most properties in common with magnesium on the periodic table. Both elements are in Group 2, known as the alkaline earth metals, and share similar physical and chemical properties such as high reactivity and the ability to form ionic compounds.
This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO
Magnesium is a metallic element with chemical properties similar to calcium.
the physical properties of magnesium can best be describes as a: shiny metal b: silver, shiny, metallic solid c: dissolves in viegar d: reacts with vinegar
Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.
