1s2 2s2 2p6 3s2 3p6 4s2
Long-hand version:
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^6
Short-hand version:
[Ar] 4s^2 3d^6
Note: The "^" symbol means the the following number is in the form of a superscript.
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
4s2 4p4
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
one electron in the 5s orbital
Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
Krypton has 8 valence electrons.The electron configuration is: [Ar]3d10.4s2.4p6.
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
The electron configuration of phosphorus is [Ne]3s2.3p3.
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
Beryllium would have that configuration
The electron configuration of iron, atomic number 26, is [Ar]3d64s2. The expanded electron configuration is 1s22s22p63s23p63d64s2.
