What is the general electron configuration for the anion formed from a neutral atom of any group VII element?
ns2np5
Why halogens have highest negative electron gain enthalpy?
Good question. Halogens have their outer electronic configuration as ns2np5 and require only one more electron to gain a stable electronic configuration. So they have a great affinity for electrons and will accept them very easily by releasing energy. So they have the highest electron gain enthalpy.
What element electron configurations would represent a halogen?
The halogens are is group VII (17), and thus they all have 7 valence electrons. These will be located in different energy levels for the different halogens, but since they are all also p-block elements, they will all have ns^2 np^5 electron configurations, where n is the period number. Examples: Cl will be [Ne] 3s^2 3p^5 and Br will be [Ar] [Ar] 4s2 3d10 4p5 (note the inclusion of the d-block electrons for Br).
Which elements have electron configurations that end in ns2np5?
halogens
Which family of elements is characterized by an ns2 np5 valence configuration?
Elements that have configuration of ns2np5 are members of the Halogen group(Group VIIA). They are, Fluorine, Bromine, Iodine and Astatine.

What is similar about the electron shells as you look across a periods?
All the elements in the same group have (usually) the same configuration of the valence electrons. For example, second-group elements (alkaline earth metals) all have ns2 configuration (where n=2-7). All halogens have ns2np5, etc. The similarity of electron configuration results in similarity of chemical properties.

How many valence electrons does an atom of any halogen have?
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance 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.
