No element is a mixture of any chemical type, because by definition an element is a chemical substance that can not be broken down into simpler substances by chemical means. However, many elements can be separated by physical means into isotopes that differ from one another in atomic number. If these are considered mixtures, then many naturally occurring elements can be considered homogeneous mixtures.
The element of lowest atomic number that has more than one stable isotope making up at least 5 % of the naturally occurring atoms is lithium, and the next lowest such element is boron. The next lowest such element is magnesium, which has three isotopes all satisfying this criterion. Titanium, with atomic number 22, has five such isotopes. Zinc, element 30, has five naturally occurring isotopes, three of which constitute more than 15 % each of the atoms in naturally occurring zinc. Germanium naturally contains five isotopes, each of which constitutes at least 5 % of the atoms, and 3 of these isotopes constitute at least 20 % of all the atoms each.
What else can I help you with?
Is calcium a homogenous mixture?
Calcium is an element, so yes.
Is pizza an example of a homogenous mixture?
No, a pizza as an example of a heterogeneous mixture as its components are obviously separate.
Is pure air a homogenous or heterogenous mixture?
Yes. Pure air is a homogenous mixture. Air is a mixture of various kinds of gases. A mixture is said to be homogenous when all its constituents are in phase. Example, a mixture of water & milk is a homogenous mixture, as water & milk both are liquids & are in phase. Same is the case with pure air. All the constituents gases of pure air are in phase with each other. Hence its a homogenous mixture.
Is Au a heterogeneous mixture?
Gold as you buy it in jewelry is often a mix. This is homogenous in state, but is heterogenous in mixing. Gold the element would be homogenous as you don't specify if anything else is in it
