An element cannot be easily broken down into other smaller materials with different?
An element cannot be easily broken down into other smaller materials with different properties because it consists of only one type of atom. Each atom of an element has a unique number of protons in its nucleus, defining its specific chemical properties. This characteristic distinguishes elements from compounds, which are formed by the combination of different elements in specific ratios.
Is it true that chemical properties of matter cannot be determined from the composition of matter alone.?
Several chemical properties can be estimated knowing the chemical composition.
Do isomers of the same molecule have identical chemical properties?
When two molecules have different configurations but the same atomic composition the two molecules cannot be said to have the same physio-chemical properties. In fact, a simple rearrangement, even with identical chemical formulas, can drastically change the properties of a substance.
Is true or false chemical properties cannot be seen?
Some can, some cannot
Can more than one element share a chemical symbol?
No. Each element is give a unique symbol. However, different isotopes of the same element will have the same symbol but are differentiated by a number subscript. C12 and C14 are both elemental carbon but contain different numbers of neutrons in the nucleas, giving them slightly different physical properties.
Can potassium substitute thorium chemical reaction?
No, potassium cannot substitute thorium in a chemical reaction because they are different elements with unique chemical properties. The substitution of one element for another in a chemical reaction is determined by the reactivity and compatibility of the elements involved.
what element cannot be either physical or chemical?
All elements have both chemical and physical properties. The question as asked has no meaning.
What are the characteristics of elements and compound?
Elements are pure substances made up of only one type of atom, which cannot be broken down further by chemical means. Compounds are substances made up of two or more different elements chemically combined in fixed ratios. Elements have unique physical and chemical properties, while compounds have properties distinct from their component elements.
What statements describes element?
elements have unique sets of properties
What are characteristics of elements?
Elements are substances that cannot be broken down into simpler substances by chemical reactions. They are made up of only one type of atom, each with its own unique properties and characteristics such as atomic number, mass, and chemical reactivity. Elements are organized in the periodic table based on their properties and atomic structure.
How does elements combine to form elements why not compounds?
Elements combine to form compounds through chemical bonding, where atoms of different elements share or exchange electrons to achieve a stable configuration. This results in the formation of compounds with distinct properties different from the elements that make them up. Elements, on the other hand, do not combine to form other elements because they are unique substances that cannot be broken down into simpler substances by ordinary chemical reactions.
What was Dalton's opinion the results of other scientists?
dalton's 6 postulates are- 1. all matter is made up of tiny particles called atoms 2.atoms are indivisible particles thtical elemat cannot be divided 3.atoms of identical elements are equal in mass and chemical properties. 4.atoms of different elements have different masses and chemical properties. 5.atoms divide in the ratio of small whno.ole

What r elements?
Elements are substances that cannot be broken down into simpler substances by chemical reactions. They are the building blocks of all matter and are composed of atoms of the same type. The periodic table organizes elements based on their atomic number and chemical properties.
What is 3 differences between compounds and elements?
Compounds are composed of two or more different elements chemically bonded together, while elements are pure substances made up of only one type of atom. Compounds have unique physical and chemical properties that are different from the elements they are made of, while elements retain their own distinct properties. Compounds can be broken down into their constituent elements through chemical reactions, while elements cannot be further broken down into simpler substances by chemical means.
What happen when you change the chemical property of aluminium?
The chemical properties cannot be changed; only after a chemical reaction the products have new chemical properties.
What can be separated by a chemical change?
In a chemical change, substances can be separated into different elements or compounds, which have distinct chemical properties. This process involves breaking and forming chemical bonds, resulting in a new substance with different properties than the original.
