What happens when elements combine to form mixtures?
When two or more elements or compounds are blended without combining chemically, you’ve got a mixture. Each substance in a mixture keeps its own properties, and mixtures can be separated using physical or mechanical means.
Has different properties than the elements that chemically combine to create them?
A compound is any combination of two or more different elements. A compound has different properties from the elements that it contains. Elements and combinations of elements (compounds) make up all the many types of matter in the Universe.
What happens when two or more elements chemically combined?
Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.
When elements chemically combine they form compounds that have properties that are similar to those of the uncombined elements?

| Term Is the following sentence true or false? When elements chemically combine, they usually form compounds that are similar to those of the uncombined elements. | Definition False |
When elements combine to form compounds are the properties of the elements retained in the compound?
Yes, when elements combine to form compounds, their individual properties are lost. In comparison, elements retain some (or many) of their property when they are mixed to form a mixture.
When elements are joined chemically in a compound they?
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).
When elements chemically combine the products have properties?
When elements chemically combine they form compounds that?
When elements chemically combine, they usually form compounds that have properties that are similar to those of the uncombined elements. What is made of two or more substances that are together in the same place but not chemically combined?
How are chemical compounds different from mixtures of elements?
Chemical compounds are very different from mixtures: The elements in a chemical compound can only be separated by destroying the compound. Some of the differences between chemical compounds and mixtures of elements are illustrated by the following example using raisin bran and “Crispix.”.
What kind of compounds are formed when elements combine?
Elements combine to form chemical compounds that are often divided into two categories. Metals often react with nonmetals to form ionic compounds. by adding or subtracting electrons from neutral atoms and
How are elements separated from a chemical compound?
The individual components of a mixture can be physically separated from each other. Chemical compounds are very different from mixtures: The elements in a chemical compound can only be separated by destroying the compound.
What kind of compounds do elements react with?
Elements combine to form chemical compounds that are often divided into two categories. Metals often react with nonmetals to form ionic compounds . These compounds are composed of positive and negative ions formed by adding or subtracting electrons from neutral atoms and molecules.
