What is the formation of chemical bond from separated atoms?
When two atoms come close together, their electron clouds start to overlap. At this point, the electrons from each atom interact and form a bond between them. This can lead to the formation of covalent, ionic, or metallic bonds, depending on the sharing or transfer of electrons between the atoms.
Unequal sharing of electrons between two bonded atoms always indicates?
Unequal sharing of electrons between two bonded atoms always indicates that the bond is polar. This means that one atom has a partial negative charge while the other has a partial positive charge. This polarity can result in different physical and chemical properties for the molecule.
What is the oxidation number for an uncombined atom?
For an uncombined atom, the oxidation number is 0. It does not give away any electrons. It does not accept electrons from anywhere either.
Is it possible to have a 100 percent covalent bond?
No, it is not possible to have a 100 percent covalent bond. Covalent bonds involve the sharing of electrons between atoms, which means there is always some degree of electron sharing rather than a complete transfer of electrons. This sharing results in a partial overlap of electron clouds between the bonding atoms.
Why is it that diatomic molecules always form nonpolar covalent bonds?
Diatomic molecules have the same electronegativity, leading to equal sharing of electrons and a symmetric distribution of charge around the molecule. This balanced sharing results in nonpolar covalent bonds.
Most often a covalent bond is formed by?
A covalent compound is always formed by the sharing of valence electrons(electrons in the last shell).

What bond results from the sharing of electrons?
When thinking of bonds, always associate "sharing" with covalent (molecular) bonds. Atoms will share electrons in order to become stable, and depending on the element, will share them equally or unequally. "Transfer" refers to ionic bonds, in which electrons are given/taken.
Unequal sharing of electrons between two bonded atoms always indicates?
Unequal sharing of electrons between two bonded atoms always indicates that the bond is polar. This means that one atom has a partial negative charge while the other has a partial positive charge. This polarity can result in different physical and chemical properties for the molecule.
Is it possible to have a reaction in which oxidation takes place but reduction does not?
Oxidation is characterized by the loss of electrons, and reduction is characterized by the gain of electrons. Since there must be an electron loser and an electron receiver, oxidation and reduction are always complimentary.
What is the oxidation number for an uncombined atom?
For an uncombined atom, the oxidation number is 0. It does not give away any electrons. It does not accept electrons from anywhere either.

Does a synthesis reaction always involve bond formation?
Yes, a synthesis reaction always involves the formation of chemical bonds between reactants to produce a new compound. This type of reaction results in the creation of a more complex product from simpler reactants.
Do atoms share pairs of electrons equally?
No. They reason it is polar is because one side is slightly positive and the other slightly negative. For this to happen, there needs to be unequal sharing of electrons. One atom will have a higher electronegativity than the other, and will naturally "keep" the electrons longer. So that atom will be slightly negative for having held onto the electron, creating a polar bond.
Does static electricity mean that the charges never move?
No, electricity always involves the movement of electrons. Static electricity is built up through friction or rubbing electrons off of other substances, so the electrons didnt get there by a current. But when a circuit is completed, the electrons can move to create an equilibrium.
How many covalent bonds does carbon almost always form in compound?
mostly double bonds and triple bonds
