An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
There Are No Other Elements or Compounds And Mixtures
No they are not.
No, elements are the most basic form of a substance, thus mixtures might be made up from different elents but elements can never be made from mixtures.
no they are not
Elements. There are only about ninety of these found in nature, compared with millions of compounds and even more mixtures.
Yes, all the mixtures contain compounds or elements.
Elements are not mixture of all. An element entirely of atoms of the same type.
Pure elements cannot be mixtures.
Chemical elements are not mixtures (I do not think to the isotopic composition).
There Are No Other Elements or Compounds And Mixtures
All minerals, except the elements and a few exceptions like graphite, are mixtures, or compounds, of elements.
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.
No, they are mixtures.
No they are not.
No they are not.
Matter can be classified as elements, compounds, or mixtures.
No, elements are the most basic form of a substance, thus mixtures might be made up from different elents but elements can never be made from mixtures.
