When two or more atoms share electrons unequally?
When atoms share electrons unequally the bond formed is a covalent bond. This occurs when there is an electronegativity difference greater than 0.4…
When electrons are unequally shared between two atoms we describe the bond as being?
In pure covalent bonds, the electrons are shared equally. In polar covalent bonds, the electrons are shared unequally, as one atom exerts a stronger force of attraction on the electrons than the other. The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity.
What occurs when atoms transfer electrons?
In ionic bonding, electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. The oppositely charged ions are attracted to each other by electrostatic forces, which are the basis of the ionic bond.
What happens when electrons are shared unequally?
A Polar Covalent Bond is created when the shared electrons between atoms are not equally shared. This occurs when one atom has a higher electronegativity than the atom it is sharing with. As a result, the shared electrons will be closer to the atom with the higher electronegativity, making it unequally shared.
What type of atoms share electrons?
covalent bond
A covalent bond involves electrons being shared between atoms. The most stable state for an atom occurs when its valence electron shell is full, so atoms form covalent bonds, sharing their valence electrons, so that they achieve a more stable state by filling their valence electron shell.
Which type of bond is when electrons are shared?
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
