What will all electron configurations for the halogen family end in?
Each Halogen ends in s2p5 with 7 valence electrons.
What is the electronic configuration of Group 17 elements?
The general electronic configuration of halogens is ns2 np5. They always have seven valence electrons. They are one electron less of having a filled outer s and p orbitals. This makes them very reactive.
What is the electronic configuration of the first 3 halogens?

What is the family number for halogens?
Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What is the general electronic configuration of Group 16 and 17 elements?
The general electronic configuration of group 16 elements is ns2np4, group 17 is ns2np5 and group 18 is ns2np6. Group 16 has two electrons less than the stable electronic configuration of the nearest noble gas. while group 17 has one electron less than the stable electronic configuration of the nearest noble gas.
What is the electronic configuration of the second element in group 17?
Answer: The general electronic configuration of 17 th group element is ns²np².
What is the electronic configuration of al 3?
[Ne] 3s² 3p¹

Where is halogen on the periodic table?
Group 17
The halogen elements are the six elements in Group 17 of the periodic table. Group 17 occupies the second column from the right in the periodic table and contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
How do you find halogens on the periodic table?
The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What is the electronic configuration of 16?
The electronic configuration of the element with atomic number 16 is 2,8,6.
How to calculate electron configuration?
If you want to do manually then follow the steps below to write shorthand electron configurations: First, find the required element on the periodic table. Now, find the atomic number of the first noble gas in the periodic table. Write the noble gas symbol in parentheses to start its electronic configuration. Then, continue writing the electron configuration of a certain element until you reach the correct number of electrons.
What are some examples of electron configurations?
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s2 2s2 2p6, using the notation explained below.
How do you find the electron configuration of an element?
Find the number of electrons (which will be the same as the atomic number of the element), then fill in the electrons in shells and sub shells according to the filling rules.
How to read electron configuration chart?
Find the element on the periodic table. Step 1: Osmium is element 76.
