WebThis need to gain a filled valance electron shell by having 8 valence electrons is known as the octet rule and explains why certain elements are stable or unstable despite being … WebUsually, though there are a few exceptions, this means elements need eight electrons in their outside energy level. So, the most succinct answer to your question is that they need to gain enough electrons to have eight in the valence level. However, please note this doesn’t make them a noble gas!

In A reaction atoms with how many valence... WebThe elements in Group 14, or 4A, only have four valence electrons in their atomic form, requiring that they either gain four additional valence electrons or lose their pre-existing four valence electrons, in order to achieve an octet configuration. Weboctet rule: Atoms lose, gain, or share electrons in order to have a full valence shell of eight electrons. Hydrogen is an exception because it can hold a maximum of two electrons in its valence level. Free Radicals Some elements, most notably nitrogen, can form compounds that do not obey the octet rule. flights phoenix to aspen

WebWhen a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl. Sodum is a cation (lost an electron and became positive) and chlorine is an anion (gained an electron and becomes negative) in this situation. WebCations are formed when atoms lose electrons, represented by fewer Lewis dots, whereas anions are formed by atoms gaining electrons. The total number of electrons does not change.
