If bonding electrons spend more time near the nucleus of one atom than near the nucleus of the other atom in a covalent bond, what happens?
A. The atoms become ions
B. A dipole is formed.
C. The atoms form a nonpolar bond
D. All of these
Would it also be possible for you to help explain the answer?

In a covalent bond, if the two bonding atoms have different elecronegativities (ability to attract electrons) the electrons will spend more time near the more electronegative one. when this occurs, a dipole is formed, with the more electronegative atom which has hold of the electrons more having a partially negative charge and the other a partially positive charge. Therefore, the answer should be B.

A false . to form ios an atom must give an electron to the other
B corract a dipole is formed with a negative value near the atom where the electron spend more time
C false

Ionic bonds take place while electrons pass from one substance to a distinctive. because of the fact of this often factors from contrary facets of the periodic desk (Na and Cl) bond ionically. Na somewhat desires to lose an electron, and Cl somewhat desires to income one, so they pass an electron between them. Covalent bonds often take place between factors that are nearer on the desk, like CO2, because of the fact they the two choose some extra electrons so they in basic terms proportion with one yet another to all type an excellent octet.

hmmm.. in covalent bonding., the atoms (non-metals) share their electrons and either form a polar or a non polar bond. polar covalent bonds occur between atoms of diffrent elements and have a positive and a negative side while non-polar occur btwn atoms of the sme element where both the nuclei are the same and exert an equal force. the electrons stay somewhere in the middle.
hope i helped

i don't believe its either a or c. In order to know if ions were formed or if a nonpolar bond is formed you must know the electronegativities of the atoms. They are not given so i would go with B.

Fromyour question, if the electrons spend more time nearer one nucleus than the other, then the molecule is polar, or a dipole.
