- 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)
What else can I help you with?
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.
What is characteristic about the outer electron shells of the halogens?
The outer electron shells of the halogens typically contain seven electrons, making them highly reactive and likely to gain one electron to achieve a stable electron configuration. Additionally, halogens have a tendency to form negatively charged ions when they react with other elements by gaining one electron.
Why id group 17 so reactive?
Group 17 elements are reactive because they only need to gain one electron to achieve a stable electron configuration with a full outer shell (octet). This makes them highly reactive as they readily react with other elements to gain that one extra electron and achieve a stable state.
Why electron gain enthalpy of Mg and P are almost zero?
The electron gain enthalpies of Mg and P are almost zero because both elements are inherently stable in their neutral state (Mg+ and P-). They have a full valence shell configuration, which makes them reluctant to gain additional electrons and become more stable. This results in low electron affinity values for both elements.
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
Which group of elements has the highest electron affinity?
Halogens have the highest electron affinity among all elements. This is because halogens have a strong tendency to gain an electron to achieve a full outer energy level and become stable.
What tends to gain electrons?
Elements on the right of the periodic table but not in group 0/8 tend to gain electrons. Those in group 7 tend to gain 1 electron and those in group 6 tend to gain 2.
Which group in the periodic table would need only 1 electron to be stable?
The elements in Group 7A (halogens) on the periodic table would need only 1 electron to achieve a stable electron configuration by filling their outermost shell with 8 electrons. For example, elements like fluorine, chlorine, and bromine each need only 1 more electron to reach stability.
How many electrons would fluorine have to gain or lose too become stable what will be the stable ion's charge?
Fluorine will gain one electron to form F- (or fluoride) ion. Fluoride ion has a charge of -1.
To become more stable fluorine is likely to?
To become more stable, fluorine is most likely to gain 1 electron and form F- ion.
How can bromine gain a stable outer electron shell?
Bromine can gain a stable outer electron shell by accepting one electron to fill its 4p orbital, achieving a full valence shell of eight electrons. This allows it to have the electron configuration of a noble gas, like argon, and become a stable ion.
What does chlorine need to become stable?
A chlorine atom needs one additional electron in order to become stable.
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.
