A bond is considered polar covalent when Electrons are transferred between the atoms One of the atoms is a metal Electrons are shared unequally between the atoms One of the atoms is larger in size than the other

Why do nonmetals tend to form anions rather than cations?

xplain the difference between ionic bonding and covalent bonding. How can we use the periodic table to help us determine the type of bonding between alums?

The geometric arrangement of electron pairs around a given atom is determined principal by the tendency to minimize between the electron pairs.

In ionic bonding, the electrons are shared between the atoms. the process of fanning an ionic bond is highly endothermic overall. the bonding that occurs is usually between two nonmetal atoms. a noble gas configuration is fanned far each element or ion. At least two of the above statements are correct.

7.46 Consider the nitrogen-oxygen bond lengths in NO2+ , NO2 , and NO3 . In which ion is the bond predicted to be longest? In which is it predicted to be the shortest? Explain briefly.

What is a metallic bond, as opposed to an ordinary covalent bond?

The following Lewis diagram represents the valence electron configuration of a main-group element. This element is in what group in the periodic table? According to the octet rule, this element would be expected to form an ion with a charge of? If X is in period 5, the ion formed has the same electron configuration as the noble gas? What is the symbol for the ion?

Part C Bond length is the distance between the centers of two bonded atoms. On the potential energy curve, the bond length is the internuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Consider that the atomic radius (sometimes called the covalent or bonding atomic radius) of an element is defined as one-half the distance between the bonded atoms in a homonuclear diatomic molecule. Actual bond lengths in molecules are determined experimentally by such methods as X-ray diffraction and microwave spectroscopy. However, these atomic radii values can be used to give an estimate of the upper limit of bond length in other (heteronuclear) molecules. Given that the atomic radii of H and F are 37.0 pm and 72.0 pm, respectively, predict the upper limit of the bond length of the HF molecule. Express your answer to three significant figures and include the appropriate units. ► View Available Hint(s) Bond length upper limit= Submit μÅ Value…

a)Compare the electrón affinity of flouorine to the ionization energy if sodium. Does the process of the eletron being “pulled” from the sodium atom to the fluorine atom have a negative or a positive E? Why is NaF a stable compound? Does the overall formation of NaF have a negative of positive E? How can this be? b) How does the concept of ionic bonding account for the properties of ionic compounds?
