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.

How many valence electrons are found in a krypton atom?
A krypton atom has 8 valence electrons in the 4s and 4p orbitals.
Why do halogens attract electrons the most?
Halogens attract electrons the most because they have a high electronegativity - a measure of an atom's ability to attract and hold onto electrons. This is due to their close-to-full valence shells and small atomic radii, which create a strong force of attraction for additional electrons.
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 does S2- have?
Sulfur (S) has 6 valence electrons. The S2- ion gains two electrons, bringing the total to 8 valence electrons.
The electrons that occupy the outermost filled shell are called?
Outer energy level electrons, or valence electron.
Do any of the halogens have their valance electrons in orbitalsof the same level?
In general, the electronic structure of the valence electrons of halogens is given by: ns2, np5 where n is the period in which the halogen is found. Since the valence electrons are found in both s and p orbitals which have slightly different energies, the valence electrons of halogens are not in orbitals of the same energy level.
How many electron containing orbitals does iodine have?
Iodine has 7 electron-containing orbitals, corresponding to its 7 valence electrons in the p subshell. These orbitals can hold a maximum of 2 electrons each.
How many valence electrons halogens?
Halogens have 7 valence electrons.
How many valence electrons do halogens gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
Which subshell of chlorine have valence electron?
3s and 3p, remember Cl has 7 valance electron. 3s^2 and 3p^5
How many valence electronss does each fluorine atom have?
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
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.
What types of orbitals contain the valence electrons in the main group elements?
The valence electrons in main group elements are typically found in the s and p orbitals. Group 1 and 2 elements have valence electrons in s orbitals, while groups 13-18 elements have valence electrons in both s and p orbitals.
Do alkali metals contain 7 valence electrons?
No. Alkali metals have one valence electrons. Halogens have 7 valence electrons.
What is the number of valence electrons of iodine?
Iodine has 7 valence electrons. It is in Group 17 of the periodic table, also known as the halogens, which have 7 valence electrons.
How many valence electron does halogen have?
Halogens each have 7 valence electrons.
