Because the proportions of the elements are different in the different compounds. They may contain the same elements, but the different proportions make them different compounds with different properties.
Yes, an element is made of millions of atoms with the same number of protons and electrons, but some atoms will have a slightly different number of neutrons. These different atoms are called isotopes.
Yes, different isotopes of the same element have different masses.
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.

Yes, an element is made of millions of atoms with the same number of protons and electrons, but some atoms will have a slightly different number of neutrons. These different atoms are called isotopes.
Isotopes of the same element have different numbers of neutrons and mass.
They are not made the same- but they come from the same element- carbon. However, carbon can take different crystal shapes. One of those is graphite, a very different one is diamond.
Yes, different isotopes of the same element have different masses.
Isotopes are atoms of the same element that are only different by the number of neutrons they have
No, isotopes of the same element are of different weight.
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
The change undergone by an atom of an element made radioactive by bombardment with high-energy protons is called transmutation. This process can result in the creation of a different element or a different isotope of the same element.
Isotopes of the same element have a different number of neutrons.
