nobel gases has few electron in the outer energy level
The first shell only hold 2 electrons, so this element has 1 electron in its first level. Hydrogen
This element is likely phosphorus (P), which has 15 electrons in total. With 5 electrons in the second energy level, phosphorus has 2 energy levels: the first energy level with 2 electrons and the second energy level with 5 electrons.
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
The element in period 3 with 8 electrons in its outermost energy level is chlorine (Cl).
They ca fill their outmost energy level by gaining or losing electrons.
The element sulfur (S) has 16 electrons. It has 2 electrons in its first energy level, 8 electrons in its second energy level, and 6 electrons in its third energy level.
An element with two energy levels can have a maximum of 8 electrons. The first energy level can hold up to 2 electrons, while the second energy level can hold up to 6 electrons.
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
7 electrons would be in the highest occupied energy level of a 7A element. Group 7A elements have 7 valence electrons, which occupy the highest energy level of the atom.
The number of electrons in the highest occupied energy level of an element in Group 15 is 5. Group 15 elements have 5 valence electrons, which occupy the highest energy level.
The maximum number of electrons that can be found in the first energy level (or inner level) of an element is 2 electrons. This is because the first energy level only has one subshell, which can accommodate a maximum of 2 electrons.
Nitrogen.
