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 do halogens gain electrons?
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.
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 valence electrons halogens?
Halogens have 7 valence electrons.
How many electrons in halogens outer shell?
There are 7 electrons! Hehe
What groups of atoms give off the most energy when they gain electrons?
Group 17, halogens
How many valence electrons do halogens gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence 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 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 are the similarities between alkali metals and halogens?
What causes these to be so reactive is the amount of electrons in the outer most level. Each level after the first (which has 2 if full) if filled will have 8 electrons. Halogens have less than that causing it to be reactive to other elements. (i don't know how many electrons it has in the outer level) The reason why it is reactive is (depending on how many electrons it has in the outer leve) because it is either trying to gain or lose those extra electrons.
