Carbon has 4 outermost electrons.
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
Helium only needs two electrons to have a filled outermost energy level.
Electronic configaration of C is 2,4. So it has Four.
To determine how many more elections are needed to fill the outermost energy level of an atom, you need to know the number of electrons already present in that level and the maximum capacity of that level. The outermost energy level can hold a maximum of 8 electrons (following the octet rule) for main group elements. Subtract the number of existing electrons from 8 to find out how many more are needed to fill the level. For example, if there are 5 electrons in the outermost level, 3 more are needed to fill it.
Nitrogen has five electrons in its outermost energy level (the second shell), which can hold a maximum of eight electrons. To achieve a stable octet configuration, nitrogen requires three additional electrons. Thus, three additional electrons are needed to fill its outermost energy level.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.

Aluminum has 3 electrons in its outermost energy level.
There are 3 electrons in the outermost level of aluminum. Aluminum is in Group 13 and has 3 valence electrons.
5 electrons
A neutral sulfur atom has 6 electrons in its outermost energy level. Sulfur has 16 electrons, with 2 electrons in the first energy level, 8 electrons in the second energy level, and 6 electrons in the third and outermost energy level.
Bromine has 7 electrons in its outermost energy level.
Oxygen has 6 electrons in its outermost energy level. This means it has a valence of 6.
Fluorine has 7 electrons in its outermost energy level. Its electron configuration is 2-7, with 7 electrons in the outermost energy level, making it highly reactive.
