It'll have to lose two to have a stable octet.
Eight electrons, called an octet, are needed by most atoms in order to be stable.
during the formation of calcium iodide,calcium donates two of its +ve ions each to a fluorine atom(2 in number) thereby making its octet and also fulfills the octet formation of each of fluorine atom..
Most elements have a stable electron arrangement when they have 8 electrons in their outer shell (hydrogen and helium are exceptions, they are stable with only 2 electrons in their outer shell), and an octet is 8 of something, hence the octet rule. Lewis dot diagrams are drawn to show how many electrons are associated with any given atom, and how the atoms are shared, in the case of covalent bonding. Generally, each atom winds up with 8 electrons. Not hydrogen.
Electron configuration of Florine: 1s^2 2s^2 2p^5 Electron configuration of Florine with an extra electron: 1s^2 2s^2 2p^6 An extra electron in places in the P orbital, so the exponent changes from a 5 to a 6. Note: The "^" symbol means the the following number is in the form of a superscript.
One
8 valence electrons
Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.

eight. it is important to obtain octet so that elements become stable.
Noble Gases are stable due to the "octet" rule (they have as many electrons as they can hold) and will not bond.
There are 9 protons and 9 electrons in a fluorine atom The only stable isotope has 10 neutrons
Eight electrons, called an octet, are needed by most atoms in order to be stable.
Fluorine has 7 valence electrons. In order to become stable, Florine will share 1 electron with another atom to get 8 electron and become stable.
Radon, being a noble gas, has 8 valence electrons, giving it a stable octet.
Fluorine will gain one electron to form F- (or fluoride) ion. Fluoride ion has a charge of -1.
