Why things look solid when atom have spaces between ions (we construct from atoms, dont we?)?

as u know atoms are microspical, normally the distance btween bonded ions are microscopical too!! infact the space between 2 ions are sometimes lesser than the diamiter of the atom itself!\n\nhere's a demonstration for u to understand this phinomina more clearly; take about 10 pieces of paper and pin tiny holes randomly on each paper. now keep each piece of paper on top of the other; eventually u will not see the otherside of the paper through it (or the visibility is very low than a single holy piece of paper), even though each single paper had singnificant nmber of holes to see through!\n\nA thing is formed of many million layers of this ions. so even though it has microbial 'holes' the loght cant go through & since these holes are microbial, the thing still feels solid because there are more dencity of ion than space!\n\nhope u understood wut i try to mean LOL

the simplistic answer involves the electrons, protons and neutrons. the more complex answer contains up quarks, down quarks- which are the building blocks of protons and neutrons. \nThen if we think about it we have also got anti-matter, which is involved in bonding and so forth, and so must be around somewhere. positrons, anti-bonding orbitals, etc.

Atoms may fill their valence shells by chemical bonding. This can be achieved one of two ways: \n1. an atom can either share electrons with other atoms (a covalent bond), \n2. or it can remove electrons from (or donate electrons to) other atoms (an ionic bond). The formation of a bond causes a strong attraction between two atoms, creating molecules or ionic compounds.

Okay now you're getting into physics or something here, so I have absolutely no idea!\n\nBut it might have something to do with.......oh yeah, ions, that's it! Ions......

Basically, It is because water is polar. The positive Hydrogen atoms and the Negative Oxygen atoms pull apart the ionic compounds. This is because ionic compounds are made of a anion and cation, which are both charged. Then, just like a magnet, they are pulled apart, and not allowed back together.

The ion has one ore more surplus electrons to fill the outer shell to 8 of them.\nElectrons repell each other, so they take a little bit more space.\nSo the negative ion is a bit bigger than the atom.

I'm sorry...my answer to this question, will either sound really smart or really stupid. \n\nMy AP Chemistry class just finished the chapter on bonding. We learned of Ionic bonds, Covalent Bonds, and Hydrogen bonds. \n\nAn ionic bond is a bond between a metal and non-metal and involves the transferring of electrons so that both atoms will become stable but with opposite charges, become attracted to each other, and form a molecule. An example is NaCl or table salt. Na is a metal, Cl is a non-metal.\n\nThe next is covalent bonding between two non-metals or non-metal and metal and involves sharing electrons. An example is O2 - oxygen.\n\nFinally hydrogen bonding is self-explanatory consisting of hydrogen and another element.\n\nBecause of the above, it is chemically impossible for two metals to bond as they will not have enough electrons to stabilize each other in the first place. \n\nI even performed this experiment in class. When a metal is heated it "oxidizes". Its atoms fuse with the oxygen atoms in the air and form the gas. For this reason a metal starts turning brown, as you are simply speeding up the process of rusting.\n\nSo your question is kind of impossible from what I have learned in class. \n\nI'm sorry if I am completely of the point in this answer (if there is something I am not getting and that two metals can actually bond) and I apologize for my ignorance and stupidity in advance. haha

No idea what your saying, but NaCl does form crystal lattices which are like perfect cubes because every Na is bonded front and back, side to side, and other side to other side with a Cl therefore forming a cube like structure. Check out the picture in the website listed below, Cl is green Na is gray.

you know its ionic because Na is a metal while Cl isnt. a metal and nonmetal almost always from an ionic bond. to draw a lewis digram, determine how many valence electons are in each and draw the diagram.. its kinda hard to explain without actually drawing it.. consult a chem bk.

The cell is still made up of many atoms, thats the only irrefutable link there. And the atom is not the elementary essential of matter, if by elementary essential you are referring to the smallest constituent of a matter. Atom is made of of sub-particles: protons, electrons, neutrons, quarks... And these are further made up of smaller sub-particles (our knowledge are always limited). Proton and nuetron have masses and volumes. Doesnt that mean they are matter too?

Crystal structure depends primarily on the size of the ions. The Cs+ ion has one closed electron shell more than the Ag+ ion. Therefore more Cl- ions can be packed around a Cs+ ion than around a Ag+ ion.\nCompare these two structure to see what I mean:\n http://cst-www.nrl.navy.mil/lattice/struk/b1.html          AgCl\n http://cst-www.nrl.navy.mil/lattice/struk/b2.html         CsCl

What the first reply means is that since it is ionic, it does not have a molecular shape.  It is NOT a molecule.  The Zn+2 ion and the Br- ions will form crystals.  They have a unit formula of ZnBr2 (not znbr2) but it is not a molecule.

If you mean atomic radius, the atoms.  The ions will most likely have shed their outer electrons to form the ion, such as Ca +2, while the atoms keep that outer shell, which increases the radius.\n\ndkrgrand:  That's the whole point.  The size of Ca (the metal) is bigger than the size of Ca+2 (the ion) because of the missing shell.  This is what was asked.

has to do with intermolecular bonds. The bonds that hold a solid together are more ridgid than that of a liquid.

it is very simple, the shells, subshells actually represent energy levels in the atoms. it is just like big building having different storeys and them again the rooms. You can compare storeys as shells, and individual apartments as subshells and the rooms in each apartment as orbitals where we the electrons are revolving

Metallic bond is the bonding between metals. \nPositive ions of metals are arranged in a regular, 3-D lattice and these ions occupy fixed position in the lattice. The electrons are delocalised and therefore they can move freely in the lattice. Because electrons are negatively charged. There will be attraction between the positively charged ions and negatively charged delocalised electrons and this attraction force hold them together, and this is called metallic bonding!\n* ions are atoms that lost or gain one or more electrons.Metals usually form "cations" because they always lost one or more electrins to form positively charged ions *

Ionic compounds (like NaCl) for lattice structures.  These lattice structures make up the crystaline arrangement of the compound.\n\nThe lattice of NaCl looks like a cube,\nhttp://zimmer.csufresno.edu/~davidz/Chem3AF97/ChB/IonicBond.html\nhttp://departments.kings.edu/chemlab/chemlab_v2/nacl.html
