Are protons from two different elements alike?

Yes.  In fact protons even from two different elements are indistinguishable.  This is a fundamental property that is quite interesting, and it results in some very odd behavior.

one way is that the atomic number is the same as the number of protons and the other way is to subtract the neutron by the mass

Because the number of protons is different from the number of electrons.\n\nFor example, the uranyl ion has a total of one hundred eight protons and one hundred six electrons.

Molecules came from atoms combining. Atoms came from protons, neutrons, and electrons combining. Protons and neutrons came from quarks combining. Quarks and electrons came from condensation from the high energy vacuum. Where that came is still a bit up in the air, but look at the website below:\n\nhttp://www.sciencedaily.com/releases/2006/05/060515232747.htm

yes you are right.. there are two sets of electrons

No, it is not possible to mix different elements on the periodic table to make a new element.\n\nAn element is defined by the number of protons in the nucleus of an atom.  A specific element has a specific number of protons in the nucleus of one of its atoms.  When you mix different elements, you are mixing atoms of that element, but the nuclei within the atoms are not mixing, they are staying separate and distinct, therefore you are only creating a mixture of two elements, not a new element all together.\n\nThe only way to create a new element would be to add protons to an atoms nucleus, something that is not easy to do, and if done, often creates a very unstable atom.\n\nA state of matter (solid, liquid, gas, plasma, Bose-Einstein condensate) are dependent on the physical conditions of the material, not the composition of the material.

Isotopes of the same element have *almost* identical chemical properties. They can be distinguished because they have different masses (from a different number of neutrons in the nucleus). But this effect is usually very small. One exception is hydrogen. The isotope consisting of one protoon and one neutron in the nucleus (deuterium) has double the mass of a regular hydrogen atom, and this can have observable effects even on the chemistry.

They ARE isotopes, but not isotopes of the same element.  Every element has isotopes -- atoms which have differing neutron counts.  But the term usually refers to different isotopes of a particular element.

One proton, it is hydrogen.  The extra mass comes from a neutron.  This isotope is called deuterium.

The atomic number of an element is equal to the number of protons the element has in the nucleus of one atom.\nThe number of protons in the nucleus determine what element it is.\n\nThe atomic mass of an element is equal to the sum of number of protons and the number of neutrons in the nucleus.  The electrons around the atom are neglected since their mass is negligible, as well as the fact that atoms can form ions by gaining and/or loosing electrons even though the element is the same.

proton and neutron, the electrons are on the outer shell

8 protons, 8 neutrons, 10 electrons

The similarity is the atomic number, as determined by the number of protons. Also the same number of electrons if not ionised.\n\nThe difference is the number of neutrons. Also differences in mass and binding energy per nucleon.\n\nA decay from 15N7 to 15O8 means the number of nucleons remains the same, but it has one more proton and one less neutron.\n\nNeutron decay is as follows:\n\n(n0) -> (p+) + (e-) + (-v)\n\nNeutron -> Proton + Electron + Antineutrino\n\nThis is negative beta decay since it produces a negative electron (which will almost certainly orbit the nucleus which now has an extra proton).\n\nThe atomic decay is:\n\n15N7 -> 15O8 + (e-) + (-v)\n\nSee the link for the appropriate notation

the proton\n\nelements with different amounts of neutrons are isotopes of the same element and elements of different amounts of electrons are ions of that element. only if you change the number of protons will you have an different element.

The amount of protons it has decides what element it will be. For compound things, it matters on what elements it is made up of and the structure of the lattice that bonds the atoms together.

Look at the periodic table. Number 1 hydrogen has 1 proton and 1 electron. Number 2 helium has 2 protons, 2 electrons and 2 neutrons.

Yes.\nStuff that make up the protons and neutrons.\nAnd stuff that make up the stuff that make up the protons and neutrons.\nAnd ..................it goes on and on, but we humans do not know where it ends, or even if it does end, there are only theories about it.
