Are convalent and ionic bonds the same? Or does one involve metals and the other nonmetals?
in words theoretical in the first (covalent) is only share the electron and the second (ionic) occur a lost of electron either. But is more probable that the first occur between not metals elements and the second between metal plus no metal
ionic is between diferents charges (electrostatic atraction/ transfere electrons) and is common between a metal and no-metal, and covalent (share electrons) and is more common metal:metal
you mean nonmetal:nonmetal
Covalent bonds are between two nonmetals (on the right of the periodic table). They involve two atoms "sharing" electrons instead of "stealing" them, so the "shared" electron spends a portion of its time around one atom in the bond, and the rest of the time around the other atom. Ionic bonds occur between a metal and a nonmetal. They involve the nonmetal atom "stealing" one or more valence electrons from the metal atom to complete the nonmetal's octet (achieving a full outer shell). So in an ionic bond, the metal loses its valence electron(s), while the nonmetal gains (a) valence electron(s).
The essential difference between covalent bonds and ionic bonds stems from the electronegativities of the elements that constitute the bond. The difference between electronegativities in covalent bonds tends to be very small, that is why you they tend to be formed by similar elements like two nonmetals. Ionic Bonds on the other hand tend to have a large electronegative difference between the two elements that make up the bond, that is why they tend to be formed by dissimal elements, for example a nonmetal and a metal =] Hope that helps ^^
They are not the same. Both phoenix and vmm's answers help. But if you want a simpler one - covalent involves "sharing" of valence electrons of two atoms, and ionic involves attraction between two oppositely charged ions. files/campbell...chem context of life www.finedrafts.com
No, they are different, but i think what phoenix says is the definition for a salt, there can be ionic bonds between amino acids in the tertiary structure of proteins and amino acids are not nonmetals, aren't they? Thus a definition, like muveokte gave, is right.
reading is fundamental.
Covalent bonds are the bonds which forms by the sharing of electrons between any of two atoms , it occours b/w nonmetals ,it is the strongest bond , difficult to break . While polar bonds r the bonds formed by the transfer of electron from the outermost shell of any atom to the other atom , the transfer of e- causes a -charge n +chrge resulting in the polarity of the molecule , bcz of the polarity it is a weak bond n the molecule can easily soluble in polar solvents So, both bonds r nt the same ..
