Ionic bonding is characterized by the combination of two elements, one is a metal while the other one is a nonmetal. Notice the compounds listed. Compounds that are bonded to H are mostly covalent, as well as O3. From the choices, we can tell that the ionic compound are:<em> LiBr</em><span><em> and MgO</em>.</span>
Answer:
helium and neon are both noble gases their outermost shells are full or stable the elements will agree with the statement s above
Answer:
A process in which a chemical change, especially decomposition, is brought about by passing an electric current through a solution of electrolytes so that the electrolyte's ions move toward the negative and positive electrodes and react with them.
The predicted order of ionization energies is Li > Na > K > Rb
<em>Atomic size increases as you go down a Group</em> (see image). We are adding electrons to increasingly larger shells.
The valence electrons are further from the attraction of the nucleus, so they are less tightly held.
Thus, <em>Li has the highest ionization energy</em> and <em>Rb the lowest</em>.
