1)  At the centre, you have the nucleus (positively charged) and, around that, there are the electronic orbitals (negatively charged).\n2)  By losing one or more electrons, to produce a cation (positively charged), e.g. Na+, Ca++, Al+++\nOr by gaining one or more electrons, to produce an anion (negatively charged), e.g. Cl-, O--, N---\n3)  An ion.

Usually, the number of electrons determines the charge of the atom. The protons determines the identity of the atom (the element). Therefore, when two protons and two neutrons are emitted, you will haev a totally different element than before, not an anion (negatively charged ion or atom).

b. electrons\n\nI really hope you are trying to answer these first before you put them on here because although we are all certainly willing to help you, you are not going to gain anything from just having the answers given to you.  You really need to try and learn this stuff.

Hmm, I don't like that previous answer.  There is a certain amount of energy holding together an atom, say uranium 235.  When bombarded with neutrons, the atom breaks apart into 2 different atoms and releases energy.  No energy is created or destroyed, as it only changes the form.

An atom is the smallest chemical entity and the part of an element which preserves its chemical character. \n\nIts parts are Protons, Neutrons, Electrons.

Everything is made of atoms, genius...\n\nC. nothing would be left.

Two or more atoms make a molecule\nMillions and millions of molecules make up a cell.

Obviously, an atom isn't the smallest particle since they are composed of sub-atomic particles.  An atom however is the smallest component of an element having the chemical properties of the element.  Once you go beyond an atom of any element, the components no longer keep the properties of that element.

Atoms consist of protons and neutrons in a nucleus, with electrons in shells round it. \nIn an uncharged/neutral atom, the number of protons and electrons are equal and this is the same as the atomic number. In the periodic table, the elements are arranged in order of increasing atomic number. \nA molecule is two or more atoms chemically bonded together.\ne.g. Ne is an atom and H20 is a molecule.

i think...\nthe atom is the smallest thing u will ever find, it doesnt divide into anything. so when you cut it up, or split it, it kind of explodes. so an atom bomb is alot of atoms exploding at the same time. funny how the smallest things in the world cause the biggest damage possible, huh?

So, I don't think we have the technology to actually know if two atoms are identical.  Right now, we just think they are based on various observations.  It could turn out that each atom is actually a mini solar system like you suggested or it could turn out to be just identical atoms.  Science is just a series of guesses based on our current observations.  It changes all the time.

An element consists of protons, neutrons and electrons. The protons and neutrons are to be found in the nucleus which is a dense ball of energy/mass. The protons are 'positive' and neutrons are 'neutral'. The electrons are to be found within the vicinity of the nucleus in set energy states defined by the quantum properties of the particular element. The electrons can be considered to particles orbiting the nucleus if you haven't done quantum physics or they can be considered to have a probability distribution of appearing at any particular point within one of the clouds around the nucleus if you have some knowledge of quantum mechanics! Elements have the same number of protons and electrons so the charge is balanced. The number of neutrons tend to equal the number of protons in light elements, although this does differ frequently! In heavier atoms there are far more neutrons (this is to maintain the stability of the nucleus - which is made unstable by too many postive charges occupying a very close space).

The atomic number is the number of protons.

ATOM: Each atom consists of a central core with negatively charged electrons revolving around the core. The core consists of positively charged protons and uncharged neutrons. The core is called the nucleus of an atom. An atom as such is electrically neutral. Atoms of different elements have different and unique characteristics. Although all atoms are made up of protons, neutrons and electrons, it is the way these subatomic particles are arranged that gives each of the atom its unique characteristics.   \n\nATOMIC NUCLEUS: The nucleus of an atom is the very dense region in its centre consisting of protons and neutrons. The size of the nucleus is much smaller than the size of the atom itself, and almost all of the mass in an atom is made up from the protons and neutrons with almost no contribution from the electrons.  The nucleus of an atom consists of very tightly bound protons and neutrons which are further composed of sub-atomic fundamental particles known as quarks.

From elementary chemistry it is known that the atomic structure of any element is made up of a positively charged nucleus surrounded by electrons revolving around it. An element’s atomic number indicates the number of positively charged protons in the nucleus. The atomic weight of an atom indicates how many protons and neutrons in the nucleus. To determine the number of neutrons in an atom, the atomic number is simply subtracted from the atomic weight.\n\nAtoms like to have a balanced electrical charge. Therefore, they usually have negatively charged electrons surrounding the nucleus in numbers equal to the number of protons. It is also known that electrons are present with different energies and it is convenient to consider these electrons surrounding the nucleus in energy “shells.” For example, magnesium, with an atomic number of 12, has two electrons in the inner shell, eight in the second shell and two in the outer shell.\n\nAll chemical bonds involve electrons. Atoms will stay close together if they have a shared interest in one or more electrons. Atoms are at their most stable when they have no partially-filled electron shells. If an atom has only a few electrons in a shell, it will tend to lose them to empty the shell. These elements are metals. When metal atoms bond, a metallic bond occurs. When an atom has a nearly full electron shell, it will try to find electrons from another atom so that it can fill its outer shell. These elements are usually described as nonmetals. The bond between two nonmetal atoms is usually a covalent bond. Where metal and nonmetal atom come together an ionic bond occurs.\n\nhttp://www.tech.farmingdale.edu/depts/met/met205/atomicbonds.html\n\nhttp://web.jjay.cuny.edu/~acarpi/NSC/5-bonds.htm

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.
