3 electrons
Aluminum has 3 electrons in 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.
Each aluminum isotope has 13 electrons. In accordance with the Aufbau Principle those electrons will fill: 1s2, 2s2, 2p6, 3s2, 3p1. The shortcut notation is: [Ne] 3s2, 3p1.
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.
Oxygen has 6 electrons in its outermost energy level. This means it has a valence of 6.
Aluminum has 3 electrons in its outermost energy level.
Carbon has 4 outermost electrons.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
There are 3 electrons in the outermost shell of an aluminum atom, as it has atomic number 13.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Each aluminum isotope has 13 electrons. In accordance with the Aufbau Principle those electrons will fill: 1s2, 2s2, 2p6, 3s2, 3p1. The shortcut notation is: [Ne] 3s2, 3p1.
5 electrons
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.
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.
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.
