How does potassium and fluorine atoms change their electron configuration to obain a noble gas structure?
Potassium must lose one electron (to have the same configuration as the noble gas argon), and fluorine must gain one electron (to have the same configuration as neon)
How element form ions that have a stable atomic structure like that found in a noble gas?
Ions are formed when elements gain or lose electrons.
What Atoms of the halogen family of elements typically gain two electrons when they react?
False; it reacts so that they acquire the electron structure of a noble gas.
What would have to gain two electrons in order to achieve the same number of electrons as a noble gas O or Sr or Na or Se or Br?
Oxygen, O ,and selenium Se. O (oxygen) would have to gain two electrons in order to achieve the same number of electrons as Ne (neon, a noble gas). Selenium would gain two to achieve the same number of electrons as Kr, krypton (noble gas). They would form the oxide, O2- and selenide Se2- ions
How can a non metal element achieve a stable electron-shell structure like that of noble gases?
Nonmetals tend to gain electrons to form ions so as to obtain noble gas configuration.
How many electrons will a sulfur atom gain or lose to achieve a noble gas structure?
Sulfur will gain 2 electrons
How does potassium and fluorine atoms change their electron configuration to obain a noble gas structure?
Potassium must lose one electron (to have the same configuration as the noble gas argon), and fluorine must gain one electron (to have the same configuration as neon)
How can elements acquire a stable atomic structure like that found in a noble gas?
Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.
Why some atom lose or gain electrons to become ions but noble gas atom never become ion?
Noble gases have a very stable structure, the outer shell of electrons is full.
How element form ions that have a stable atomic structure like that found in a noble gas?
Ions are formed when elements gain or lose electrons.
How many electrons must be gained or lost for Iodine to achieve a noble gas electron configuration?
It must gain one electron to achieve a noble gas electronic structure, just like other halogens.
What Atoms of the halogen family of elements typically gain two electrons when they react?
False; it reacts so that they acquire the electron structure of a noble gas.
Why do halogens gain electrons?
Halogens have 7 valence electrons, in order to become a noble gas you need 8 so instead of losing electrons, it would be easier just to gain 1. That would make Halogens a negative 1 If you do the dot structure you can see that there is only room to gain 1 electron when forming a bond.
How are elements form ions that have a stable atomic structure like that are found in a noble gases?
There are three different ways for this. Elements can either gain electrons or lose electrons or share electrons and attain a stable noble gas electronic configuration.
What happens to the structure of an atom to change the atom into an ion?
The loss or gain of electrons transform an atom in an ion.
How many electrons does calcium need to gain to become more stable?
Far too many - it needs to gain 16 to get to Krypton which is the next noble gas (energetically impossible) - It is far easier for it to lose 2 (which it does) to get to the Argon structure
