In the modern Periodic Table, these elements belong to group 17. These elements have s2 p5 electron configuration. Hence they need one more electron from an electron donor to fulfill its valence shell to obtain noble gas configuration.
The elements in the group 7A has 7 electrons in their outermost energy level. They gain 1 electron to get the noble gas configuration. The elements in the group 7A are called halogens.
Group 7A elements, also known as the halogens, need to gain one electron to achieve a stable electron configuration, typically by gaining an electron to achieve a full outer energy level of eight electrons (octet).

Generally they will gain 1 electron, rather than losing.But there are compounds in which the elements lose up to 7 electrons (as in HIO4, HClO4).

How many electrons does fluorine need to satisfy the octet rule?
Fluorine needs one additional electron to satisfy the octet rule, giving it a total of 8 valence electrons and achieving a stable electron configuration.
What determines an element's reactivity?
An element's reactivity is determined by its electron configuration and the ease with which it can gain, lose, or share electrons to achieve a more stable electron configuration. Elements with one or a few valence electrons tend to be more reactive as they can easily form bonds. Additionally, the position of the element on the periodic table can also influence its reactivity, with elements in the alkali metals and halogens groups typically being highly reactive.
What can you conclude about a ecosystem with many trophic levels?
it is a stable ecosystem
How many atoms is at Saturated carbon atom bonded to?
A saturated carbon atom is bonded to four other atoms. In organic compounds, this typically includes other carbon atoms or hydrogen atoms. This arrangement allows the carbon atom to reach its stable configuration with a full outer shell of electrons.
How many elements can the 3rd shell hold?
The 3rd shell can contain 18 electrons. The elements that have a 3rd shell as the outer shell are the the elements in period 3, where the 3s and 3p orbitals are filled to a maximum of 8 electrons. The 3d orbitals are filled in the 4th period in the transition elements.
How many electrons does barium lose to become a stable octect?
Two electrons.
How many electrons must beryllium loose to become stable?
Beryllium is a stable element.
How many electrons does group 2 lose?
Group 2 elements lose 2 electrons to achieve a stable electron configuration.
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 group is stable and will not bond?
Noble Gases are stable due to the "octet" rule (they have as many electrons as they can hold) and will not bond.
How many electrons does group 6A need to gain to become a noble gas?
Group 6A elements have 6 valence electrons and need to gain 2 electrons to achieve a full octet and become stable like a noble gas.
How many electrons does sulfur gain or lose to become stable?
Sulfur gains 2 electrons to become stable, forming the sulfide ion (S2-). This allows sulfur to achieve a full outer electron shell, following the octet rule.
How many electrons does a magnesium atom need to lose to become stable?
2
How many electrons does Ca lose to become more stable when bonding?
Calcium (Ca) typically loses 2 electrons to become more stable when bonding, as it has 2 valence electrons in its outer shell. By losing these electrons, calcium achieves a full octet, making it more stable.
All atoms become stable when they have how many valence electrons?
Atoms become stable when they have a full outer electron shell, which typically means having 8 valence electrons (except for hydrogen and helium, which are stable with 2 valence electrons). This stable configuration is known as the octet rule.
How many electrons an atom has lost gained or shared to become stable?
the oxidation number
How many electrons must tantalum need to gain or lose to become stable?
Tantalum needs to lose 2 electrons to become stable. Tantalum has 73 protons, so losing 2 electrons will give it a full outer shell of 71 electrons, which is the most stable configuration for the element.
