A 94C stamped 4F typically refers to a classification from the U.S. Selective Service System, indicating that an individual is classified as unfit for military service. The "4F" classification was used during draft processes to denote physical or mental disqualifications. The "94C" might refer to a specific form or document related to this classification. For detailed information, it's best to consult official records or the Selective Service System directly.

The possible values for a 4f sublevel are 14. This means there can be a maximum of 14 electrons in a 4f sublevel.
The 4f subshell has higher energy compared to the 4s, 4p, and 4d subshells. This is due to the increased screening effect and poor shielding of the nuclear charge by intervening 4d and 4p electrons. The 4f subshell is further away from the nucleus, leading to higher energy levels.
Electrons are added to the 4f orbitals from the 5d orbitals in the lanthanide and actinide series of elements. The 4f orbitals are filled after the 5d orbitals are filled due to the overlap in energy levels, leading to the stability of the 4f electrons in these elements.
some atoms have 5, some have none. the max is 5
The elements of the 4f series are called lanthanides. They are a group of metallic elements that have similar properties and occupy the f-block of the periodic table.
The energy sublevel being filled by the elements Ce to Lu is the 4f sublevel. These elements are part of the lanthanide series and have their outermost electrons entering the 4f orbital.
Yes, "4f" is a valid orbital shell designation in the electronic configuration of atoms. It represents the fourth energy level and the f subshell within that energy level.
4F, when interpreted as a hexadecimal number, is equal to 79 in decimal. This is calculated by taking 4 times 16 (which equals 64) and adding 15 (the decimal equivalent of F), resulting in 79. Therefore, as an integer, 4F is 79.
If the valence electrons are being added to the 4f orbitals, that means the element is lanthanides or actinides which further proves that the element is a heavy element and a member of f -block.
The maximum number of electrons that can exist in 4f orbitals is 14.-pg. 110 Modern Chemistry table 2:)
