But this is not the only way that compounds can be formed. 9. The atom that gains electrons has an overall negative charge, and the atom that donates electrons has an overall positive charge. 0 Answers/Comments. Atoms can also make chemical bonds by sharing electrons equally between each other. Ionic bonds are most likely to be formed by atoms that have just one or two electrons in addition to a filled outer shell or are just one or two electrons short of acquiring a filled outer shell. The ionic bond is formed through the transfer of electrons from the metal atoms to the non-metal atoms. When an element donates an electron from its outer shell, as in the sodium atom example above, a positive ion is formed (Figure 2). Ionic bonds are formed when atoms _____ electrons while covalent bonds are formed when atoms _____ electrons. Electron transfer produces negative ions called anions and positive ions called cations. A covalent bond involves a pair of electrons being shared between atoms. Moving on, let's take a look at some characteristics of ionic bonding. answer choices. Summary: In the ionic bonding of Sodium Chloride (NaCl), the sodium atom loses one electron (to become a cation), and the chlorine atom gains one electron (to become an anion). Chemical bonding is the joining of atoms to form new substances. An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons. An ionic bond forms when _____.a. The attraction of each atom's nucleus for the valence electrons (electrons in the outermost energy level) of the other atom . Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. For example: When a sodium atom reacts with a chlorine atom, creating an ionic bond between them, a new substance is formed - NaCl which is sodium chloride - table . A) Two atoms fuse together to form a chemical bond. Ionic compounds are typically neutral. Thus, when two atoms of the same element such as two chlorine atoms combine, they form a covalent bond.
