A pure substance has only one kind of particle. Sulfur is an example of a pure substance.
Compounds cannot be separated by physical means while elements are made up of only one kind of matter.
An element is a material that has only one kind of atom. For example- hydrogen is an element- it has only hydrogen atoms. Another element is oxygen- it has only oxygen atoms. But if we combine the two elements together, add a spark, we have a bang- and we now have a compound- water. Compounds are 2 or more elements that combine chemically.
Compounds can be separated into their constituent elements only by a decomposition reaction.
yes (but only in the case of ionic compounds).
Binary compounds
The answer is likely supposed to be "an element", but ANY chemical substance contains only one type of particle, whether it is an element (atoms) or a compound (molecules). It is only combinations of elements or compounds (alloys, solutions, mixtures) that contains multiple types of particles.
they are elements compounds are when you take two or more elements and mix them together.
The elements are things in their purest form whereas compounds are multiple elements combined together to form a compound. For instance, Carbon (C) is an elements whereas Carbon Dioxide (CO2, or Carbon + two Oxygens) is a compound.
Elements are pure substances that cannot be broken down into simpler substances by chemical reactions, while compounds are substances made up of two or more elements that are chemically bonded together. Both elements and compounds are pure substances, but compounds are made up of more than one type of atom, whereas elements consist of only one type of atom.
No. Compounds can have any number of elements above one.
atoms in elements are one kind of atom where as atoms in compounds are different atoms example gold is a element and it is made up of only gold atoms and water is a compound and it is made up of hydrogen and oxygen atoms
Elements are substances that cannot be broken down into simpler substances by chemical means and are listed on the periodic table. Compounds are substances made up of two or more elements chemically bonded together in fixed proportions.
