What is the electronic configuration of group elements?
These elements also will also have similar electron configurations to each another because they are in the same group; these elements have 6 valence electrons….S, P, D, and F Blocks.

What is the group number of the element in the periodic table?
The group number in the periodic table represents number of valence electrons of the elements in a certain group. For example, all the elements in Group−1 have 1 electron in their outer most shell.
What is the electronic configuration of 16?
The electronic configuration of the element with atomic number 16 is 2,8,6.
What is the general electronic configuration of Group 16?
ns2np4
Group 16 elements have 6 electrons in their valence shell and their general electronic configuration is ns2np4.
How many groups are in the Periodic Table 8 or 18?
The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups.
What is the electronic configuration of Group 18 elements?
Group-18 elements or the noble gas group has a general electronic configuration of ns2np6 except helium which has 1s2. Among the group-18 elements, helium is used in magnetic resonance imaging (MRI) due to its unique properties.
What is the electronic configuration of Group 15 elements?
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is equal to the principal quantum number.
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.
How do you calculate an electron configuration?
To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three Sciencing_Icons_Science
How do you find the group number of an element?
The group of an element is predicted from the number of electrons in the valence shell or/and penultimate shell as follows: a)For s block elements ,group number is equal to the number of valence electrons. b) For p block elements ,group number is equal to 10+number of electrons in the valence shell.
Why do elements in the same group have the same electronic configuration?
Electronic Configuration in Groups. Elements in the same group have the same number of electrons in their outermost shell leading to similar valence shell electronic configuration. Thus, we observe a similar trend in the properties and chemistry of the elements in the same group.
What is the general electronic configuration of elements 13 to 18?
The elements of groups 13 to 18 are called p-block elements or representative elements and have a general electronic configuration ns2, np1-6. The elements of the group 16 and 17 are called chalcogens and halogens respectively.
