How many electrons are present in non- metals in their outermost shell...
Non-metals generally contain 4,5,6,7 or 8 electrons in their outermost orbit or shell.
The number of valence electrons in carbon, nitrogen, oxygen and fluorine are 4, 5, 6, 7 respectively.

How many electrons are present in non- metals in their outermost shell...
Explanation:
Non-metals are elements that are typically poor conductors of heat and electricity. They tend to gain or share electrons in chemical reactions and have a tendency to form negative ions. The number of electrons present in the outermost shell of non-metals can vary, but it is generally between 4 and 7.
The correct answer is option 'D', which states that the number of electrons in the outermost shell of non-metals can be 4, 5, 6, or 7.
Reasoning:
1. Non-metals are located on the right side of the periodic table.
2. The number of electrons in the outermost shell is determined by the group number of the element.
3. In group 14, non-metals such as carbon (C) and silicon (Si) have 4 electrons in their outermost shell.
4. In group 15, non-metals such as nitrogen (N) and phosphorus (P) have 5 electrons in their outermost shell.
5. In group 16, non-metals such as oxygen (O) and sulfur (S) have 6 electrons in their outermost shell.
6. In group 17, non-metals such as fluorine (F) and chlorine (Cl) have 7 electrons in their outermost shell.
Summary:
In summary, the number of electrons present in the outermost shell of non-metals can vary, but it is generally between 4 and 7. This is because the number of electrons in the outermost shell is determined by the group number of the element. The correct answer is option 'D', which states that the number of electrons in the outermost shell of non-metals can be 4, 5, 6, or 7.

How many electrons are present in non- metals in their outermost shell...
The non Metals are in 3, 4, 5, 6, 7 and 8 group and the group show the valence electron. So they have 3, 4, 5, 6 and 7 valence electron. And 8th group are noble family they don't have valence electron
