Phosphorus
To determine an element from its electron configuration, simply add up the superscript numbers (those are the numbers of electrons in each sublevel): 1s22s22p63s23p3: 2+2+6+2+3=15, and find the element with the matching atomic number*. In this case, Phosphorus.
*Note: This method is not correct if the electron configuration of an ion is given, as the number of electrons in an ion does not match its atomic number.
The ground-state electron configuration for krypton (Kr) is [Ar] 4s² 3d¹⁰ 4p⁶. This means that krypton has a total of 36 electrons distributed among its electron shells.
The given electron configuration corresponds to the ion with a charge of -2, which is the oxide ion (O^2-). This ion is formed by the element oxygen when it gains two electrons to achieve a stable electronic configuration.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The electron configuration for V3 is Ar 3d2.

The ground-state electron configuration for krypton (Kr) is [Ar] 4s² 3d¹⁰ 4p⁶. This means that krypton has a total of 36 electrons distributed among its electron shells.
No, this is not a possible ground state electron configuration. It violates the Aufbau principle, which states that electrons fill orbitals starting from the lowest energy level. The correct electron configuration for xenon (Xe) is 1s22s22p63s23p64s23d104p6.
The given electron configuration corresponds to the ion with a charge of -2, which is the oxide ion (O^2-). This ion is formed by the element oxygen when it gains two electrons to achieve a stable electronic configuration.
The outer energy level for an atom is determined by the highest principal quantum number, n. In this case, the highest n value in the electron configuration is 4. Therefore, the outer energy level is the fourth energy level.
Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.
The bromide ion, which has a charge of 1-, has one more electron than a neutral bromine atom. Its electron configuration is isoelectric with the noble gas krypton, so it has 36 electrons. Its electron configuration is [Ar]3d10 4s2 4p6. I apologize that the superscripts are not working. I put a space between the different sublevels to make it easier to understand.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
A cation has a depleted electron configuration.
The electron configuration for beryllium, Be, is 1s22s2.
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The electron configuration of francium is [Rn]7s1.
