Most do. They are called isotopes. For a particular element the number of protons in the nucleus is the same, but there can be different numbers of neutrons. For example uranium235 and uranium238 where the number is called the mass number, which is the sum of the numbers of protons and neutrons in the nucleus. Isotopes of hydrogen are specially given individual names (hydrogen, deuterium, tritium) but they are all "chemically" hydrogen (protons=1, electrons=1).
Elements are as simplified as you can get. They only contain one atom. There are no such things as elements containing more than one type of atom. Those are called compounds. For example a hydrocarbon is a compound containing carbon and hydrogen atoms only. Hydrocarbons CANNOT be elements because they can be simplified to two elements and two different atoms, hydrogen and carbon.
So - a short answer to your question - none. Hope i helped
All compounds contain more than one element and more than one atom.
Every element has a specific amount of protons and neutrons in its nuclues. If an atom has more protons and neutrons than another element, it is heavier.
By definition, an Element contains only one kind of atom - atoms of that element. If it has more than one kind, it is a compound, not an element.

NO.Never. Element is a substance made up of a single type of atom.It is the compound made up of different atoms shantanu satpute class 9
All compounds contain more than one element and more than one atom.
Copper is an element. An element consists of one type of atom. If there is more than one type of atom it can be a mixture of elements, or it could be a compound or alloy, but not an element.
Elements contain only one type of atom (atoms with the same number of protons). Compounds contain more than one element, and thus contain atoms with different numbers of protons. Compounds can be converted into elements, but elements are not reducible to anything simpler (besides subatomic particles).

atom.
It is for this reason that large nuclei contain proportionally more neutrons than light elements
By definition, an Element contains only one kind of atom - atoms of that element. If it has more than one kind, it is a compound, not an element.
No. (and there is no such thing as "the standard atom"). All isotopes of a given element contain the same number of protons.
Water is a molecule rather than an atom because it consists of more than one atom. In fact it consists of atoms of two different elements.
ions like sulphate ions,carbonate ions etc...are the ions which contain more than one atom.
more than one atom of different elementsdifferent elements chemically combined.
