What else can I help you with?
How do you identify the difference between elements mixtures and compounds from their names and formulas?
Elements have names from the periodic table. Names of compounds takes parts of at least 4 chapters in a beginning chemistry textbook. Learning these is not a simple paragraph answer. The same for their formulas. Mixtures are generally named from their contents.
Can compounds be physically separated?
it depends on wht compound it its
Do all compounds contain at least one element?
A compound consists of at least two elements chemically bonded together.
What are three elements whose atoms are likely to form bonds?
Helium, neon and argon are the least likely elements to form compounds.
Which group of metals on the periodic table is the least stable and consequently its elements are found in nature only in compounds?
The Alkali metals lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What is the same between compounds and mixtures?
Compounds are chemically mixed. You can't see the ingredients, elements, etc. in compounds. Compounds make a new thing. Compounds can't be separted easily. Compounds can't contain mixtures. Mixtures are not chemically mixed. You can see the ingredients, elements, etc. in the mixture. Mixtures don't create anything new. Mixtures can be separated easliy. Mixtures can contain compounds. Both mixtures and compounds are mixes of things. Both mixtures and compounds contain 2 or more elements, ingredients, etc. Hope I helped!
How are mixtures and compounds a like?
Both contain at least two distinct kinds of atoms.
Are mixtures and compounds a like?
Both contain at least two distinct kinds of atoms.

Are elements denser than compounds?
Elements are often denser than compounds, but not always. In fact the least dense substance known is hydrogen, which is an element.
What is the basic building block of all the compounds?
The basic building block of all compounds is atoms. Compounds contain atoms of at least two different elements bonded to one another. Thus, atoms of elements are what form compounds.
Can atoms of different elements combine to form a compound?
Yes: compounds have to consist of at least two different elements.
What is the smallest number of elements needed to make a element?
It is 2. Compounds consist of at least 2 elements.
What are the inorganic elements?
All elements other than carbon are likely to form inorganic compounds, and even carbon is at least sometimes found in inorganic compounds such as calcium carbonate.
Do all compounds contain at least one element?
A compound consists of at least two elements chemically bonded together.
How deos the number of known compounds compare with the number of known elements?
There are at least five million distinct chemical compounds known. This compares to only 91 naturally occurring elements and about thirty more synthetic elements.
