There are so, so, so many combinations possible, already with the 20 simplest, most occurring elements.
2020 = 1.05*1026 and 1*2*3*4*5*6*78 .....*19*20 = (20!) = 2.5*1018 or even something in between are more possibillities than we have dicovered yet or will ever discover!!
The 92 elements combine with one another in a myriad of combinations. Not all substances are elements and compounds. Many substances are mixtures which are not chemically combined.
Those 92 elements can combine in a myriad of combinations to form an infinite number of different substances.
Although a substance may contain millions of negatively charged electrons, it also contains millions of positively charged protons. The object will be neutral when the number of protons equals the number of electrons.
Compound is a substance composed of two or more elements combined in definite proportions, can be broken down by chemical means. Element is a substance that cannot be broken down into simpler substances even by chemical means.
No, they're about as different as it's possible for two elements to be.
Formaldehyde is one possible answer, nitrous oxide is another.
The smallest substance of Iron is itself (Fe) The smallest substance of water (H2O) is Hydrogen (H) and Oxygen (O) Compared results are Water having 1 more element than Iron. 2 elements are derived from water and only 1 from Iron.
A compound is defined as a substance that contains at least two chemical elements and always has a constant mass ratio between elements for each possible pair of the elements that are present in it.
There are millions of possible combinations.
It is possible only because of different number of neutrons.
Although a substance may contain millions of negatively charged electrons, it also contains millions of positively charged protons. The object will be neutral when the number of protons equals the number of electrons.
elements can combine to form new substances with different properties.
The definition of an atom is that is the smallest possible particle of ONE element. I think you meant to ask "What is a substance that is made of two or more elements." The answer to this question is, "A compound".
The element carbon has the ability to link with itself in long chains containing from two up to hundreds of units. It can also form rings and bond with many other elements and they often with each other. This ability means that many millions of possible compounds can be formulated. The chemistry of carbon is called organic chemistry as life is based upon it.
It is not possible because we need a differentiation between elements, including different chemical symbols.
Atoms are the smallest possible units of PURE substances called elements. There are are only about 118 elements known to exist.When atoms of different elements join together chemically (they share electrons between each other), they form a new substance called a compound. The smallest possible unit (or joined up atoms) of a compound is called a molecule. There are potentially hundreds of thousands of compounds.
Yes, if they are both ions
