How many electrons do atoms need to be stable
WebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to … Usually in chemistry we're concerned with chemical reactions. Reactions where th… Neon has 8 valence electrons which is a filled second electron shell and is therefo… WebAn atom of cobalt has more electrons. An atom of cobalt has a lower number of neutrons.

Did you know?
WebHow many electrons does carbon need to become stable? 4 Two atoms will never share 4 electrons each, so how can carbon become stable? The carbon could bond with 4 … WebJun 15, 2015 · The explanation is simple: the story is that nice and smooth, when you have to loose one or two electrons. Things in the middle don't just lose 8 electrons or get 5 extra. Extra charge means extra energy: an ion with a large charge is actually getting unstable because of the coulomb energy.
WebTo achieve stability, carbon must find four more electrons to fill its outer shell, giving a total of eight and satisfying the octet rule. Carbon atoms may thus form bonds to as many as four other atoms. For example, in methane (CH _4 4 ), carbon forms covalent bonds with four hydrogen atoms. WebHow many electrons do elements in groups 14 and 17 need to gain to achieve a stable configuration? Group 1 elements need to lose one electron to stabilize. Group 14 …
WebTo be stable an atom will gain, lose, or share electrons to complete the outer most energy level (electron shell). Octet Rule because levels 2 and 3 need 8 electrons to be stable. How do we know if an atom is active or not? Look at the outer most electron shell (energy level). Why do atoms need 8 electrons to be stable?
