Almost all elements can be combined into compounds, for example water=h20 steel=iron and carbon. Their properties usually change. For example when carbon is added to iron to make steel, it becomes stronger and more durable. Humans use compounds to our advantage, adding various elements to materials to make them water proof, stronger, more flexible, harder e.g
What else can I help you with?
Elements combined to form compounds is a chemical change?
Yes, the combination of different elements to form compounds involves a chemical reaction, which is a type of chemical change. This process typically involves the breaking and forming of chemical bonds between the atoms of various elements to create new substances with different properties.
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
When elements combine to form compounds their properties change?
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.
When the elements combine to form compounds what happens to the chemical and physical properties of the elements?
When elements combine to form compounds, the chemical properties change because new chemical bonds are formed between the elements. This can result in new properties for the compound compared to the individual elements. The physical properties may also change, such as its melting point, boiling point, and appearance, due to the arrangement of the atoms and molecules in the compound.
What is The properties of a compound are different from those it is made of?
When compounds are formed, the properties of the individual elements change. This is because the atoms in a compound are now bonded together in a new structure with unique physical and chemical properties that are different from those of the individual elements. For example, sodium and chloride individually are reactive, but when combined as sodium chloride (table salt), it becomes a stable compound that is non-reactive.
Do the properties of elements change when combined to form compounds true or false?
no they dont chane
Do compounds containing iron and copper look like the elements iron and copper?
Compounds containing iron and copper do not typically resemble the pure elements in their metallic form. When combined in compounds, the properties and appearance of the elements change due to their chemical bonding with other elements.
Elements combined to form compounds is a chemical change?
Yes, the combination of different elements to form compounds involves a chemical reaction, which is a type of chemical change. This process typically involves the breaking and forming of chemical bonds between the atoms of various elements to create new substances with different properties.
If properties of elements change they are mixed together and the mixture if called what?
If the properties of elements change when they are mixed together, the mixture is called a compound. Compounds result from chemical reactions between elements, where the atoms are bonded together in specific ratios. These compounds often possess unique properties distinct from their individual element components.
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
What are the compounds that change the properties of glass?
What compounds Change the properties of glass?
When elements combine to form compounds their properties change?
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.
What is the name of the two compounds whose elements properties change when they are combined?
Hydrogen (H2) and Oxygen (O2) have both 0. In the combined compound H20 or water (by combustion), H has (+1) and O has (-2). The biological relevance is seen in e.g. Knallgas-bacteria.
When the elements combine to form compounds what happens to the chemical and physical properties of the elements?
When elements combine to form compounds, the chemical properties change because new chemical bonds are formed between the elements. This can result in new properties for the compound compared to the individual elements. The physical properties may also change, such as its melting point, boiling point, and appearance, due to the arrangement of the atoms and molecules in the compound.
How do the properties of the parts of a mixture compared to the properties of the parts before they become A mixture?
Because there is no chemical reaction, the properties of the elements and compounds do not change when they form a mixture.
What is The properties of a compound are different from those it is made of?
When compounds are formed, the properties of the individual elements change. This is because the atoms in a compound are now bonded together in a new structure with unique physical and chemical properties that are different from those of the individual elements. For example, sodium and chloride individually are reactive, but when combined as sodium chloride (table salt), it becomes a stable compound that is non-reactive.
Can chemicals change by being combined with other chemicals?
Chemicals yes, elements however, no. Elements are themselves chemicals, Burn hydrogen in oxygen and you'll end up with water, another chemical.
