Because an element is an element and a molecule is a molecule; they are different chemical entities and of course they have different chemical and physical properties.
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed.
no they dont chane
Compounds have properties unlike those of their constituent elements, due to the chemical bonding that occurs between the elements to form a new substance with unique characteristics. This phenomenon is known as emergent properties, where the compound displays traits that are distinct from the individual elements it is composed of.
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
Chemical properties of compounds refer to how they interact with other substances in chemical reactions, such as their reactivity, ability to form bonds, and composition of elements. Physical properties include characteristics such as color, density, melting point, boiling point, and solubility, which can be observed without changing the chemical identity of the substance.
Physical properties of metals include: luster, malleability, and ductility. Chemical properties include: forming cations, and reacting with nonmetals to form ionic compounds.
Elements combine to form compounds through chemical reactions. These compounds have different properties than their individual elements, resulting in a wide range of substances found in nature and synthesized in laboratories.
Because there is no chemical reaction, the properties of the elements and compounds do not change when they form a mixture.
The sharing of electrons by elements to form compounds is a chemical property. It involves the rearrangement of atoms to form new chemical substances with different properties, rather than dealing with the physical characteristics of the elements themselves.
When two compounds are mixed together, they can form a new compound through a chemical reaction. The resulting compound may have different properties than the original compounds and can be identified through various chemical tests or analyses.
Lutetium tends to form compounds with elements that have similar chemical properties, such as other lanthanides and some transition metals. It does not typically form stable compounds with alkali metals and alkaline earth metals, as they have very different chemical properties from lutetium.
