No. Two atoms of the same chemical facet are frequently not similar. First of all, tbelow is a range of possible states that the electrons of an atom can occupy. Two atoms of the very same facet deserve to be various if their electrons are in different states. If one copper atom has actually an electron in an excited state and also an additional copper atom has actually every one of its electrons in the ground state, then the 2 atoms are various. The excited copper atom will certainly emit a little of light when the electron relaxes earlier dvery own to the ground state, and the copper atom already in the ground state will certainly not. Due to the fact that the says of the electrons in an atom are what recognize the nature of the chemical bonding that the atom experiences, 2 atoms of the same facet can react differently if they are in various states. For circumstances, a neutral sodium atom (say, from a chunk of sodium metal) reacts through water much even more violently than an ionized sodium atom (say, from a bit of salt). Chemists know this incredibly well. It"s not enough to say what atoms are connected if you desire to completely define and also predict a reactivity. You have to likewise specify the ionization/excitation says of the electrons in the atoms. Even if left alone, an atom frequently does not come via an equal number of prolots and electrons.
But what if two atoms of the very same element both have actually their electrons in the exact same claims. Then are they identical? No, they are still not similar. Two atoms of the very same element and in the same digital state can be traveling or rotating at different speeds, which affects their ability to chemically bond. Slower relocating atoms (such as the atoms in solid iron) have time to develop stable bonds, while faster relocating atoms (such as the atoms in liquid iron) cannot form such stable bonds. A slow-moving moving tin atom acts in different ways from a rapidly moving tin atom.
But what if two atoms of the very same element both have their electrons in the very same states, and the atoms are both traveling and also rotating at the very same speed. Then are they identical? No. Although 2 such atoms are essentially chemically identical (they will chemically react in the same way), they are not entirely the same. There"s more to the atom than the electrons. There"s also the nucleus. The nucleus of an atom includes neutrons and protons bonded tightly together. The same chemical facet can have a various variety of neutrons and still be the very same element. We describe the atoms of the very same facet with different numbers of neutrons as "isotopes". While the certain isotope involved does not impact just how an atom will react chemically, it does determine exactly how the atom will certainly behave actually in nuclear reactions. The many prevalent nuclear reaction on earth is radioactive degeneration. Some isotopes degeneration incredibly easily right into various other aspects and emit radiation, while various other isotopes carry out not. If you are doing carbon dating, the truth that a carbon-12 atom is not the same to a carbon-14 atom is essential to the dating procedure. Sindicate counting the variety of carbon atoms in a sample will not offer you any information around the age of a sample. You will certainly have to count the number of different isotopes of carbon rather.
But what if 2 atoms are the exact same aspect, have electrons in the very same state, are traveling and rotating at the same rate, and have the very same variety of neutrons; then are they identical? No. Similar to the electrons, the neutrons and proloads in the nucleus can be in various excited states. In enhancement, the nucleus overall deserve to turn and also vibprice at assorted speeds. Therefore, even if all else is identical, two gold atoms have the right to have their nuclei in different excited states and behave in a different way in nuclear reactions.

To state the situation succinctly, it is exceptionally hard to have two atoms of the exact same element be precisely identical. In fact, being successful in coaxing a team of atoms to be extremely cshed to identical was worthy of a Nobel Prize. With that sassist, don"t think that atoms have actually individual identities beyond what has actually been mentioned below. If 2 carbon atoms are in the precise exact same molecular, atomic, electronic and nuclear says, then those two carbon atoms are the same, no issue where they came from or what has happened to them in the past.
