Gaining of 1 electron take Fluorine to nobel gas state
It has 7 electrons in its valance shell so it needs only 1 electron to form a octet; the Nobel gas configuration.
Lithium electron configuration: 1s2 2s1, or in shorthand: [He] 2s1 Thus in LiF the Li cation (Li missing one electron to get its nobel gas configuration of He) it is Li+: 1s2 2s0, or in shorthand: [He] 2s0, This ion does NOT have 8 (octet) electrons, although it has a nobel gas configuration of He: 1s2.
No - but the potassium ion does
A Nobel gas, or an atom with a filled valance shell. In Nobel gas configuration.
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
nobel gases has few electron in the outer energy level
Gaining of 1 electron take Fluorine to nobel gas state
Halogens are in the seventh group on the periodic table, and thus have seven electrons in their outer shell. In order to attain a noble gas configuration, it must gain an electron to form an octet, which is when eight electrons are in the outer shell.
It has 7 electrons in its valance shell so it needs only 1 electron to form a octet; the Nobel gas configuration.
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.
Take a look at the shells, each has a certain number electrons orbiting the central nucleus, in the case of the Nobel Gases, they all have 8 electrons except of course for hydrogen which has 2. Each ring has a certain number of electrons which causes the atom to be more stable than others. The outermost is called a valence electron shell. In the case of the Nobel Gases it causes the element not to be as reactive to other substances. Depending upon how many electrons are in the outer shell, will denote how reactive an atom will be. Those atoms with only 1 electron, will be quite non reactive where as those that are missing just one electron from making it complete will be quite reactive. They have the same outer electron structure.

He achieved a Nobel prize in physics
Halogens have 7 valence electrons and nobel gases have 8. Each atom wants 8 or none electrons according to the octet rule. Therefore, nobel gases are relatively unreactive b/c they already have 8 Halogens only need 1 more valence electron, making them very reactive.
