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.
What else can I help you with?
Which class of nonmetals is the most reactive?
The halogens are the most reactive class of nonmetals due to their high electronegativity and tendency to gain electrons to achieve a stable electron configuration. This results in them readily forming compounds with other elements.
Does chlorine want to gain or lose electrons?
As fluorine is a halogen (the group in which the elements are more reactive as they are one electron lesser than that of the octet configuration)and hence it can only gain electrons.
How many valence electrons do Halogens have?
The number of electrons are different from one to another, however all of them have seven electrons in the valence shell.
When forming an ion bromine is most likely to gain how many electrons?
Bromine is most likely to gain one electron when forming an ion, as it is in Group 17 of the periodic table (halogens) with 7 valence electrons. By gaining one electron, bromine achieves a stable octet and forms a Br- ion.
What group of elements has seven valence electrons?
The name of the family is the Halogen family.
How many electrons do the halogens gain?
They gain one.
How many electrons do the halogens have in their outer most energy level?
The halogens have 7 electrons in their outer shell desparate to gain the 1 electron to make a full shell of 8 electrons.
How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
What groups of atoms give off the most energy when they gain electrons?
Group 17, halogens
How many valence electrons halogens?
Halogens have 7 valence electrons.
Why are the halogens so reactive and noble gases not reactive?
Because noble gases don't need to give or take any electrons - they have a perfect octet configuration. Where as halogens need to gain or lose electrons and will easily react to other halogens that need to lose or gain.
How many electrons in halogens outer shell?
There are 7 electrons! Hehe
Elements that typically attract electrons are what?
include the halogens are nonmetals
Do halogens combine easily with metals?
Yes, halogens combine easily with metals to form ionic compounds. Metals tend to lose electrons and become cations, while halogens gain electrons to become anions. This transfer of electrons results in the formation of stable ionic bonds, making halogens highly reactive with metals. For example, sodium chloride (table salt) is formed when sodium (a metal) reacts with chlorine (a halogen).
What is Oxidation number of halogens?
Halogens typically have an oxidation number of -1 in compounds because they have seven valence electrons and need to gain only one electron to achieve a full octet. Exception: in compounds with oxygen or other halogens, halogens may have positive oxidation numbers.
What group achieves the electron configuration of a noble gas by gaining one electron?
All halogens have 7 valence electrons. They gain one electron and achieve noble gas electronic configuration
How many valence electrons do Halogens have in p subshell orbitals?
Halogens have 5 electrons in their outermost p shell in their electrically balanced state. The p shell has 3 orbitals in each energy level. Halogens have 2 filled orbitals each with 2 electrons in them and one orbital with only one electron in it. In order to obtain the stable noble gas electron configuration, halogens gain one electron to completely fill the p shell on the outermost energy level. This gives halogens a charge of -1.
