What type of substance contains more than one kind of element?
A compound contains more than one kind of element. Compounds are made up of two or more different elements that are chemically bonded together. This differs from elements, which are pure substances made up of only one type of atom.
Why is the element Xenon called The Alien?
Xenon is sometimes called "The Alien" because it is a noble gas with properties that are quite different from other elements. It is chemically inert and has low reactivity, making it stand out from the more reactive elements in the periodic table. This unique behavior gives it an "alien" quality compared to other elements.
How do astronomers identify elements of the stars?
Elements are identified based on their absorption spectra. Every element absorbs a unique set of frequencies when light passes through it. Scientists can determine which elements are present based on which portions of the star's light are absorbed.
Are there as many absorption lines in the solar spectrum as there are elements present in the Sun?
There are a lot more. Each element has several possible absorption lines. In fact the element iron has several hundred lines.
Which element of the sun is 90 percent?
Hydrogen is the most abundant element in the sun, making up about 75% of its mass. Helium is the next most abundant element, at around 24%. Together, these two elements account for roughly 99% of the sun's composition.
Is an element a compound?
no, but compounds are made of elements chemically combined.
When an element is combined to another element the substance is what?
When an element is combined with another element, the resulting substance is called a compound. Compounds are formed through chemical reactions where atoms of different elements bond together to form a new substance with unique properties.
What two or more elements combined chemically form?
a new element
Is carbondioxide a element compound or mixture?
Compound. It is two elements chemically combined.
Is suphar dioxide an element or a compound?
compound. Because a compound is chemically combined of 2 elements
Is an element composed of atoms of two or more compounds chemically combined?
Compounds are composed from elements.
When is an element said to be chemically reactive?
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
Is argon an element compound or a mixture?
Argon is an element. It is a noble gas that exists as individual atoms and is not chemically combined with other elements.
Which statements describe elements?
An element is a pure substance that cannot be broken down into a simpler form. An element is made of two or more atoms that are chemically combined. All elements are listed on the periodic table of elements.
Are mercury atom joined to an oxygen atom a mixture compound or element?
It isn't a element, as an element is one atom. It would be a compound if the elements chemically combined, but if they didn't, its a misture
What is the difference of a element and a compounds?
An element is composed of only one type of atom. Compounds are composed of different types of atoms (different elements) that are chemically combined.
Why water is compound not a element?
Water, H2O, contains two different elements, H and O, that are chemically combined, and is therefore a compound.
