The act of bonding repositions the electrons, which changes the base properties of the united molecule. It is for this reason, for example, that oxygen O2 has different properties than ozone O3 even though both compounds only have the element of oxygen.
The properties of the elements are not changed; new compounds with different properties are obtained.
The density, hardness, heat of fusion etc. of copper are not changed for every compound of Cu.
properties of elements dont change when mixed
Yes,mixing with other compounds can change the properties of a substance. The melting point, boiling point changes. Chemical properties are also can be changed.
Color change indicates a chemical reaction has occurred. The mixture of elements has different chemical properties than the original individual elements.
Elements have different properties because elements can be further divided than atoms and can be mixed by another element

Because the elements can combine in many ways to form compounds, and compounds can be mixed in many differed ways. Moreover, some elements occur in different forms. The elements carbon and hydrogen alone combine for form thousands of compounds.
They both are mixed together but compounds are mixed chemically and mixtures are mixed phisically.
In scientific terms, an element is anything that can be found on the Periodic Table of Elements (PTE). It is a pure substance, not mixed with anything else. Compounds are a combination of 2 or more elements. They cannot be found on the PTE.
the similarities between compounds and mixtures are that they are both made up of two or more elements and that they could both be separated and then mixed with different elements to make a new mixture and compound.
Mixture may consists of elements , compounds or both.
Gold is an element. It can be mixed with other elements to form compounds, but gold itself is a pure substance, not a mixture or a compound of elements.
Elements can be combined in several different ways. Elements which undergo no chemical reactions when combined are called mixtures. Normally, the elements in a mixture retain their original properties, but metals can be combined into mixtures called alloys to produced new properties, though these properties tend to be the intermediate sum of the collective properties of the metals involved. Elements which combine chemically to produce entirely new substances are called chemical compounds.
