How do you identify elements in a compound?
To identify elements in a compound, you can look at the chemical formula of the compound. Each element will be represented by its chemical symbol in the formula. For example, in water (H2O), "H" is the chemical symbol for hydrogen and "O" is the chemical symbol for oxygen. You can also use a periodic table to identify elements based on their atomic number and chemical symbol.
What indicator is used to determine a compound?
The molecular formula and structure of a compound are used to determine its identity. Analytical techniques like spectroscopy, chromatography, and mass spectrometry are commonly employed to identify compounds by examining their physical and chemical properties.
What are three physical properties used to identify compound?
Three physical properties used to identify compounds are melting point, boiling point, and density. These properties can be compared to known values of compounds to determine the identity of an unknown compound.
Why is it important to identify substances by their physical and chemical properties?
These properties are specific for each substance.
How can the periodic table identify the properties of chemical families?
Periodic table group elements with same properties together. Hence their properties can be identified.

Can knowing about chemical properties can help identify elements and compounds?
Yes, knowing about chemical properties can help identify elements and compounds because each element and compound has unique chemical properties that can be used for identification. Properties such as melting point, boiling point, density, and reactivity can be used to differentiate between different substances. By comparing the observed properties of an unknown substance to known properties, it is possible to determine its identity.
How can you identify that a change is chemical?
A change is chemical if the substance's chemical composition is altered, resulting in the formation of new substances with different properties. Look for indicators such as color change, gas production, temperature change, or formation of a precipitate to help identify a chemical change.

Why chemical properties not always used to identify minerals?
The stripe, and color
How do scientists identify the chemical properties of a material?
Scientists use various analytical techniques such as spectroscopy, chromatography, and mass spectrometry to identify the chemical properties of a material. These techniques help in determining the molecular structure, composition, and behavior of the material at a molecular level. By comparing the results with known standards, scientists can identify and characterize the chemical properties of the material.
How do scientists identify minerals?
Scientist identify minerals by Their Special properties. An example of a special propertie is a Chemical Reaction .
What can be used to identify a substance or to predict how will behave?
Physical and chemical properties can be used to identify a substance or predict how it will behave.
What has a combination of letters and numbers that indicates which elements make up a compound?
It is the chemical formula of a compound. It helps to identify the elements and their ratios i the compound. Also it is easy to use the formula to describe a compound.
Why is it important to identify substances by their physical and chemical properties?
These properties are specific for each substance.
How can the periodic table identify the properties of chemical families?
Periodic table group elements with same properties together. Hence their properties can be identified.
