What is the electronic configuration of the elements of group 16?
The symbol of elements written in the square bracket is the nearest noble gas elements. Now, we can say that the general electronic configuration of group 16 elements is ns2np4.
What is the electron configuration for an atom with 16 electrons?
FIGURE 5.9 The arrow shows a second way of remembering the order in which sublevels fill. Table 5.2 shows the electron configurations of the elements with atomic numbers 1 through 18….

How many valence electrons are present in the valence shell of group 16 elements?
The element having atomic number 16 will have (2,8,6) configuration. So there are 6 valence electrons present in the outermost (valence) shell.
What is electronic configuration of group?
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 group I elements?
For group −16. elements the general electronic configuration is ns2np4. Six electrons are present in the valence shell.
Which is the electronic configuration of outermost shell of group 16?
The elements of Group 16 have `ns^(2) np^(3)` general electronic configuration in the outermost shell.
How do you write a valence configuration?
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.
How do you write valency and electronic configuration?
Write the electronic configuration and valency of 1 to 30…
- Hydrogen (H) Valency = 1. Electronic Configuration : 1.
- Helium (He) Valency = 0. Electronic Configuration : 2.
- Lithium(Le) Valency = 1.
- Beryllium(Be) Valency = 2.
- Boron(B) Valency = 3.
- Carbon(C) Valency = 4.
- Nitrogen(N) Valency = 3.
- Oxygen(O) Valency = 2.
What is a valence electron configuration?
Key Terms. Valence electrons – the electrons located at the outermost shell of an atom. Electron configuration – the arrangement of electrons around the nucleus of an atom.
What is the valence electronic configuration of Group 15?
All Group 15 elements have the electron configuration ns2np3 in their outer shell, where n is equal to the principal quantum number.
How do you write valence electron configuration?
How do you find the electron configuration of a group?
To determine the group, we need to understand some rules:
- If the element is in s block, then the group number is equal to the number of valence electrons.
- If the element is in the p block, then the number of the group can be determined by the formula: (number of valence electrons + 10).for groups.
