Is helium has chemical properties so different from those of the other elements that it cannot be placed in any group?
Helium has unique chemical properties that distinguish it from other elements, particularly due to its complete valence shell, which makes it chemically inert and stable. Unlike other noble gases, helium does not readily form compounds and exhibits minimal reactivity. While it is placed in Group 18 (the noble gases) of the Periodic Table, its properties are indeed different enough that it sometimes behaves unlike heavier noble gases. Nonetheless, its placement in Group 18 is based on its similar lack of reactivity rather than its chemical behavior.

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.
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 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.
Why element cannot group by physical properties?
Elements cannot be grouped solely by physical properties because these properties can vary widely within a category, leading to inconsistencies. For example, metals, nonmetals, and metalloids exhibit diverse physical characteristics, such as boiling points, densities, and states of matter at room temperature. Additionally, elements may share similar chemical properties regardless of their physical characteristics, making chemical behavior a more reliable basis for classification, as seen in the periodic table. Thus, grouping by physical properties alone can overlook essential relationships and trends among elements.
Is true or false chemical properties cannot be seen?
Some can, some cannot
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

This characteristic distinguishes elements from compounds, which are formed by the combination of different elements in specific ratios.
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?
An element is only made up of its protons, neutrons and electrons.A compound is made up of elements.A compound can be broken down into to its original elements easier than an element can be broken into its (protons, neutrons and electrons).
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.
Substances that cannot be broken down by chemical?
Substances that cannot be broken down by chemical means are known as elements. Elements are made up of one type of atom, and they cannot be broken down into simpler substances through chemical reactions. Examples of elements include gold, oxygen, and carbon.
