By transfer or sharing of electrons.
By acquiring noble gas configuration elements become stable .
Noble gases have completely filled electronic configuration and hence they are chemically inactive / inert / do not form bond with other elements.
Noble gases do not typically form bonds with other elements due to their stable electron configuration with a full outer shell.
The elements in Group 18 are called the noble gases, also known as inert gases. These elements are known for their low reactivity due to their stable electron configuration.
The group of elements that have a stable electron configuration are the noble gases.
K+And the K ion configuration is 1s2 2s2 2p6 3s2 3p6Noble gases have the configuration up to 3p6Pseudo noble gases have it up to 3d10
Elements want to gain or lose electrons in order to achieve a stable electron configuration, usually by attaining a full valence shell of electrons. This helps them achieve a more stable, lower energy state, similar to the configuration of noble gases.
If alkali metals loses one electron, they achieve the electronic configuration of the nearest noble gases.
The stable ions of all the elements except the Transition metals, Actinide, and Lanthanide series (that is the d and f block elements) form stable ions that are isoelectronic to a nobel gas by gaining or losing electrons in order to achieve an s2 p6 stable octet. For example, sodium will lose one electron to have the same electron configuration as neon, while nitrogen will gain three electrons to become isoelectronic to neon.
Other elements can acquire a noble gas configuration by either gaining or losing electrons. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration. Elements on the right side of the periodic table, such as halogens, tend to gain electrons to achieve a noble gas configuration. Elements in the middle of the periodic table may gain or lose electrons to acquire a noble gas configuration, depending on the specific element and its properties.
because they have completely filled electronic configuration.
either by losing, gaining or sharing electrons.
