The electron configuration of a neutral chromium atom is [Ar]3d54s1. The electron configuration for manganese is [Ar]3d54s2. The first electron removed from a chromium atom is the single 4s electron, leaving the electron configuration [Ar]3d5. The first electron removed from a magnesium atom is one of the 4s2 electrons, leaving the electron configuration [Ar]3d54s1. Removal of a second electron from a chromium atom involves the removal of one of the 3d electrons, leaving a configuration of [Ar]3d4, which is not a very stable configuration, and requires more energy to achieve. Removal of a second electron from a magnesium atom involves the removal of the second 4s electron, leaving a configuration of [Ar]3d5, which is more stable and requires less energy to achieve.
There can only be 1 outer energy level.
The valence electrons of manganese are located in the 4s and 3d energy levels.
binding energy
The binding energy of uranium can be calculated by subtracting the sum of the masses of its protons and neutrons from its actual mass. This difference in mass, when converted to energy using Einstein's equation E=mc^2, yields the binding energy for uranium.
Vanadium has 5 electrons in its outer energy level.

No, binding energy cannot be negative. Binding energy is always a positive quantity that represents the energy required to hold a system together. If the binding energy were negative, it would imply that the system is in an unstable state.
There can only be 1 outer energy level.
No. Binding energy differs from element to element,
There can only be 1 outer energy level.
Vanadium is important because of its many unique characteristics. The most common use of vanadium is in alloys for making rust-resistant steel used in manufacturing tools, engines, gears, springs, missile cases, jet-engine housings, nuclear-reactor parts, and superconductive magnets. Vanadium foil is used in binding titanium to steel. Vanadium compounds are used for dyeing and printing fabrics. Vanadium pentoxide (V2O5) is used in ceramics and as a chemical catalyst.
Higher binding energy is preferred because it indicates stronger binding forces holding particles together. Higher binding energy results in more stable nuclei with lower potential for decay.

The greater the binding energy the more stable the nucleus is.
Binding energy is the energy required to hold the nucleus of an atom together. It is contributed to by the strong nuclear force that overcomes the electrostatic repulsion between positively charged protons in the nucleus. The binding energy is responsible for the stability of atomic nuclei.
The outermost electrons of vanadium are located in the 4s and 3d orbitals. These electrons generally occupy the 4s orbital before filling the 3d orbitals.
