What is the frorm of an element that has a different molecular structure?

they are called allotropes.  An example is diamond, and graphite. Both are pure carbon, but the bonding structures are different.  another example is O2 (oxygen gas) and O3 (ozone gas). Both are pure oxygen but the molecules are different.

In chemistry, a metal (Greek: Metallon) is an element that readily forms ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions (cations) surrounded by a cloud of delocalized electrons. The metals are one of the three groups of elements as distinguished by their ionisation and bonding properties, along with the metalloids and nonmetals. On the periodic table, a diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals. Elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals.

A molecule is made up of atoms.

look it up on any periodic table - like the one linked below... good luck!

Go to this site and it will show you structures of a whole bunch of molecules with Carbon and without, by formula and by name, kind of mess around with it for a while. http://www.chem.purdue.edu/gchelp/molecules/index.html

Becauz they are transition metals, Baby. This can be better understood by studying about orbitals, hybridisation and energy levels and transitions of an electron from one orbital to another.\nHey, it's not too difficult if u'r really interested.

Um, there's over a hundred elements.  I'm not going to name them all for you.  Look at a periodic table.  I'm sure there's one in your chemistry book.

1)electron ...(also negative meson)\n2)the atom is the basic (many atoms make molecule and so on)\n3)polymer (the most famous are protiens)

well family 13 has B and Al.  they are metaloids that are great lewis acids.  they have interesting bonding strategies that defy the normal octet rule.

A compound contains more than one element (H2O).  A molecule may contain atoms of one element only (O2).

Most professional papers that I read refer to it as just water ion (in its charged form).  This a water molecule with an over-all positive charge.  I do not believe that its structure is known, but I could be wrong about this.\nSee example reference below:

You should expect a molecular compound to form between N and O (as opposed to an ionic compound).  This is because N and O are both nonmetals.  An ionic compound will form when a metal and a nonmetal combine.  I believe that this is what your question is getting at.

its C2F6,it actually contains two carbon atoms in a molecule and each one of them has three fluorine atoms attached to it,both these carbon atoms are bonded by a covalent bond!!!

Elements differ primarily by number of protons.  An atom containing one proton, for example, is always called hydrogen.  Protons are contained in the nucleus along with neutrons.  Electrons "orbit" the nucleus  ("orbiting" isn't a correct way to describe the electron quantum mechanical sense, but it's more-or-less helpful to think of it this way).  Protons have a positive charge, electrons a negative charge and neutrons a neutral one.\n\nElements may also vary within themselves.  Some forms of elements have more neutrons than others.  These are called isotopes of each other and have different masses.  They're referenced by their mass numbers such as "Carbon-14" or "Carbon-12".  Here Carbon-14 has two "atomic mass units" (amu) more mass than carbon 12.  Each proton and each neutron contributes one amu to the mass so carbon 1-4 has two more neutrons than carbon-12.\n\nElements may also vary by electronic species.  When neutrally charged, the same number of electrons "orbit" the nucleus as there are protons in the nucleus.  Sometimes atoms either gain or lose some electrons to become negatively or positively chaged overall (as opposed to neutral where the positive proton charges cancel exactly the negative electron charges).  These are called "ionic species" or simply "ions".

Atomic radii decrease as one moves from left to right across a period and while moving up a group. The atomic radius is the distance between the nucleus and the valence electrons.\n\nElectron affinity, ionization energy, and electronegativity increase as one moves from left to right across a period and while moving up a group. \n\nElectron affinity is the ease with which an atom can accept an electron. The halogens (F, Cl, I, etc.) have the highest electron affinity, with F having the highest of all elements. The alkaline metals (Li, Na, K, etc.) have the lowest electron affinity, with Fr having the lowest of all elements.\n\nIonization energy is the energy needed to remove an electron from an atom. All atoms want to form a stable octet. Since alkaline metals only have one valence electron, it takes very little energy to remove an electron from them. In contrast, it takes a lot of energy to remove an electron from a halogen.\n\nElectronegativity is the strength of the attraction an atom has for an electron in a chemical bond. Halogens are the most electronegative, while the alkaline earths are the least. The electronegativity of two elements can inform you of what type of chemical bond they will form. If Na (low EN) and Cl (high EN) form a bond, Cl will rip the lone valence electron away from Na, forming an ionic bond. If C and O form a bond, the atoms will share electrons because their EN's are very close. Since O is more EN, it will have a slight negative charge, and the bond will be a polar covalent bond. If C and C form a bond, both have the same EN, and they will form a non polar covalent bond.

Common elements that exist as diatomic molecules are H, N, O, F, Cl, Br, and I.\n\nSo these elements are most commonly found in nature as H2, N2, O2, F2, Cl2, Br2, and I2.

An element, sometimes called a chemical element, is a substance that cannot be divided or changed into other chemical substances by any ordinary chemical technique.\n\nElements outside of nature are those that have been created by smashing molecules together in labrotories.  They generally have a very short halflife.\n\nElements occuring in nature can be found on the periodic table and go from Hydrogen (1) to Uranium (92).\n\nSome ancient philosophies used a set of classical elements to explain patterns in nature.  These were Air, Fire, Water, Earth and Aether.  These were used throughout the middle ages to help people explain things that weren't fully understood like how some objects floated, why people got sick, etc.\n\nIn popular western media these elements were revitalized and include Air, Earth, Fire, Water and sometimes Spirit.\n\nThey are also now used in some neo-pagan religious practices. \n\nRegards,\nArmus
