What rule says atoms will gain or lose electrons?
Octet Rule
It does not form chemical bonds, or compounds. To 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.
What is the rule that states that ions will gain or lose electrons until they have the electron configuration of a noble gas?
The octet rule
The octet rule states that elements form chemical compounds so that each atom will acquire the electron configuration of a noble gas. Most noble gases have eight valence electrons, except for helium, which has only two.
What states that atoms lose gain or?
The octet rule states that atoms lose, gain, or share electrons in order to acquire a full set of 8 valence electrons. In covalent an bonding the atom share electrons to achieve octet. Describe the formation of a covalent bond. The sharing of electrons.
Atoms of nonmetals tend to gain electrons in order to fill their outermost principal energy level with an octet. Atoms form compounds in ways that give them eight valence electrons. Metals tend to lose electrons to achieve this configuration. Nonmetals tend to gain electrons to achieve this configuration.
How do atoms follow octet rule?
There are two ways in which atoms can satisfy the octet rule. One way is by sharing their valence electrons with other atoms. The second way is by transferring valence electrons from one atom to another. Atoms of nonmetals tend to gain electrons in order to fill their outermost principal energy level with an octet.
Which atoms must obey the octet rule?
For the elements in the second period of the periodic table (principal energy level n=2), the s2p6 electrons comprise the octet, and no d sublevel exists. As a result, the second period elements (more specifically, the nonmetals C, N, O, F) obey the octet rule without exceptions.
Will I gain or lose electrons?
In general, metals will lose electrons to become a positive cation and nonmetals will gain electrons to become a negative anion. When an ionic compound forms, the more electronegative element will gain electrons and the less electronegative element will lose electrons.
What states that atoms tend to gain lose or share electrons until they are surrounded by eight valence electrons?
The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
What happens when an atom loses an electron?
An atom that loses one or more electrons forms a cation ion. An atom that gains one or more electrons forms an anion ion. State the octet rule. Atoms lose or gain electrons to match the valence-electron configuration of a noble gas.
Why are noble gases stable under the octet rule?
The Octet Rule Noble gases have complete outer electron shells, which make them very stable. Other elements also seek stability, which governs their reactivity and bonding behavior. Halogens are one electron away from filled energy levels, so they are very reactive.
Why do noble gases have complete electron shells?
Noble gases have complete outer electron shells, which make them very stable. Other elements also seek stability, which governs their reactivity and bonding behavior. Halogens are one electron away from filled energy levels, so they are very reactive.
When do you need to write the full electron configuration?
If you need to writethe full electron configuration for an anion, then you are just adding additional electrons and the configuration is simply continued. For example, we know that Oxygen always forms 2- ions when it makes an ion. This would add 2 electrons to its normal configuration making the new configuration: O2-1s22s22p6.
