What is Formal charge of the atom?
Formal charge of an atom is the charge assigned to it in a molecule. FC = V - (N + B \2) Where V is the number of valence electrons of the atom in isolation (atom in ground state); N is the number of non-bonding valence electrons on this atom in the molecule; and B is the total number of electrons shared in covalent bonds with other atoms in the molecule. There are two electrons shared per single covalent bond.
How is a hydrogen bond different from a covalent bond?
Hydrogen bonds are electrostatic attractions between a hydrogen atom, bonded to a more electronegative atom of one molecule AND a more electronegative atom of another molecule, but there is no sharing of electrons. In covalent bonding, atoms share electrons to form molecules.
What is the difference dipole and covalent?
Dipole means that there's an uneven distribution of electrons in a molecule; this usually occurs when you've a molecule with atoms of very different electronegativities. Covalent describes bonds that have electrons shared between atoms. The opposite of this would be ionic, where one atom takes electrons from another atom.
How are covalent bonds and atoms related?
If an atom reacts with another atom, one electron from the first atom is shared with the second atom. Since this electron is being shared, it spends some of its time orbiting the first atom and some of its time orbiting the second atom. At the same time, one electron from the second oxygen atom is shared with the first oxygen atom and spends time orbiting each atom. This pairing of the electrons forms covalent bonds. Covalent bonding forms covalent compounds. Water is a compound of hydrogen and oxygen atoms,which bond together in covalent bonds to form water molecules.

The covalent bond between a hydrogen atom and the oxygen atom in water is formed when?
The covalent bond between a hydrogen atom and and an oxygen atom when the two atoms share electrons. They form a water molecule when there are two hydrogen atoms sharing electrons with one oxygen atom.
What is the role of electrons in the formation of covalent bonds?
The outer shell electrons of the atom form covalent bonds.
When two fluorine atoms share a pair of electrons the bond that forms a?
A fluorine atom forms a covalent bond with another fluorine atom to produce the fluorine molecule which is gaseous at room temperature.
Is formed when an atom shares electrons?
This is a molecule having a covalent bond.
What is Formal charge of the atom?
Formal charge of an atom is the charge assigned to it in a molecule. FC = V - (N + B \2) Where V is the number of valence electrons of the atom in isolation (atom in ground state); N is the number of non-bonding valence electrons on this atom in the molecule; and B is the total number of electrons shared in covalent bonds with other atoms in the molecule. There are two electrons shared per single covalent bond.
How does the carbon atom complete its octet?
it forms covalent bonds by sharing electrons
What forms from a neutral atom or molecule by adding electrons to it?
A positive ion, or cation forms.
How is a hydrogen bond different from a covalent bond?
Hydrogen bonds are electrostatic attractions between a hydrogen atom, bonded to a more electronegative atom of one molecule AND a more electronegative atom of another molecule, but there is no sharing of electrons. In covalent bonding, atoms share electrons to form molecules.
What do you call a bond that forms when electrons are tansferred from one atom to another?
This is a covalent bonding.
What is the difference dipole and covalent?

Covalent describes bonds that have electrons shared between atoms. The opposite of this would be ionic, where one atom takes electrons from another atom.
When an atom forms a bond what are the 3 things that its electrons can do?
The electrons can be shared equally (covalent bond). The electrons can be shared but one atom provides those electrons and the other provides none (dative or coordinate covalent bond). The electrons can be donated by one and accepted by the other atom (ionic bond).
What type of bond is a molecule of water?
It is a polar covalent bond. This is due to unshared and unpaired electrons around the oxygen atom.
What is it called when electrons are shared in bonds?
A covalent bond is when electrons are shared in bonds.
