Which elements have to gain or lose only one electron to become stable?

- This is determine by the number of valence electron(which is found by locating the group number the atom resides in) the atom have. Once located, you then recall that all the atoms wants to obtain stability like the Nobel gases (located in group 8 of the Periodic Table).
Ex. Sodium (Na) has 11 electron.
To gain stability like the gases, Na will gain one more electron to look like the Nobel gas Neon (Ne)

∙ 13y agoi think you mean " what indicates how many electrons must an element gain or lose to become stable?" anyway, if that's what you meant, it's the atomic number. (the group) :)
Wiki User
∙ 13y agoAn element will either share, take, or lose electrons until it has 8 electrons in its outer valence shell. The only exception is hydrogen who only wants 2 total.

What is outer shell electrons do group 1 elements?
i guess you mean that the group 1 elements usually lose a electron in order to become stable because the outermost of the group 1 elements have only one valence electron and it is easy to lose one than to gain seven.
What do radioactive elements gain when they emit radiation?
They become slightly more stable with each decay until they become stable and stop decaying.
How many electrons would fluorine have to gain or lose too become 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.
How many electrons doe lithium gain or lose?
Lithium(Li) gains 1 electron to become stable.
What charge results when specific elements become an ion?
Either it loose electron or gain and if loose then it get positive charge and if gain then be negatively charged ion
Which group in the periodic table would need only 1 electron to be stable?
The atoms of Group 17 elements must gain one electron in order to become stable.
Does cl gain or lose to become more stable?
to become stable, it will gain an electron from a metallic atom otherwise it will mutually share electron(s) with another non - metallic atom, or even with itself
How does silicon become stable?
Elements get stable only when it completes electron octate in its outermost orbit. Elements make compounds with other elements to gain or reduce electrons to get stability. silicon make bonds with oxygen and make silicon dioxide to get stable.
To become more stable fluorine is likely to?
To become more stable, fluorine is most likely to gain 1 electron and form F- ion.
What is outer shell electrons do group 1 elements?
i guess you mean that the group 1 elements usually lose a electron in order to become stable because the outermost of the group 1 elements have only one valence electron and it is easy to lose one than to gain seven.
How many electrons does it take for hydrogen and helium to become stable?
Helium is already stable. Hydrogen should gain or lose one electron to be stable.
What do radioactive elements gain when they emit radiation?
They become slightly more stable with each decay until they become stable and stop decaying.
When comparing the electron configurations of neon and fluorine what must happen for fluorine to become stable?
flourine must gain one electron
Why does potassium atom become positively charged and fluorine becomes negatively charged?
Potassium only needs to lose on electron (gain a positive charge) to have the same electron structure as Argon and thus very stable. Similarly, fluorine only needs to gain one electron (become negatively charged) to gain the very stable Neon structure.
What iodine makes?
Iodine is reactive because it has 7 valence electrons and is unstable. It needs one more electron to get 8, which would give it a noble gas configuration, and which would make the iodine atom stable. Iodine reacts with other elements in order to gain the needed electron and therefore become stable.
What makes iodine reactive?
Iodine is reactive due to its ability to readily gain or lose electrons. It has a strong tendency to accept an electron, making it a good oxidizing agent. Additionally, iodine can form stable compounds with various elements and molecules, which further contributes to its reactivity.
How many electrons would fluorine have to gain or lose too become 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.
