they are 2 completely different substances usually- If they combine they make a compound or a molecule. this is 2 substances together.
Example-
H2O=Oxygen+2 Hydrogin atoms(water)

∙ 11y agoTo an atom to be changed, the nucleus of the particular atom should change, and they are considered as nuclear reactions, not chemical reactions.

∙ 10y agoNo. Elements are not created or destroyed in any chemical reaction. Combining elements chemically can only ever form a chemical compound. The nuclei of the elements are never affected.

What type of substance contains more than one kind of element?
anything that is not in the periodic table probably contains more than one kind element. steel, plastic, rubber are all examples
Do other planets have oxygen?
The only planet with oxygen (known to Man) is Earth.That is to say, only Earth has a significant amount of the element oxygen in its atmosphere.Other planets do have oxygen, but it is chemically combined in the form of compounds, like carbon dioxide.
What are the four most common elements found in your solar system?
The two most common are hydrogen (90%), helium (9%) and the rest make up the final 1% The oceans are 1/3 hydrogen, we have relatively little hydrogen on the inner planets because the sun's radiation "blew" most of it (the lightest element) to the outer planets like Jupiter, which is made mostly of hydrogen and is more massive than all of the other planets combined.
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.
When an element is combined to another element the substance is what?
When one element is combined with another element, a chemical compound results. The elements are chemically bonded together to make this compound.
Is an element a compound?
no, but compounds are made of elements chemically combined.
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.
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.
What is a free element?
A free element has an oxidation number of 0. It is not combined with or chemically bonded to any other element. Examples of free elements are nitrogen molecule and hydrogen molecule.
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.
Is magnesium carbonate a compound or an element?
Magnesium carbonate is a compound. It consists of the elements magnesium, carbon and oxygen chemically combined. As a rule of thumb anything with two or more elements chemically bonded together is a compound.
