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.

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.
What group of elements has seven valence electrons?
The name of the family is the Halogen family.
The element iodine is a halogen True or false?
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
Which element most readily accepts electrons?
Fluorine
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.
How many electrons do the halogens gain?
They gain one.
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.
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.
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.
What groups of atoms give off the most energy when they gain electrons?
Group 17, halogens
Which elements are most likely to gain electrons?
metals have a tendency to lose electrons while nonmetals have a tendency to gain electrons. Metals are located left of the stair-step line and non-metals are located to its right.
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 gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
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 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.
Why does halogens attract electrons the most?
Halogens has a very high electronegativity.
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
