How many unpaired electrons are in the nickel atom?
A nickel atom has an atomic number of 28, which means it has 28 electrons. Its electron configuration is [Ar] 3d^8 4s^2. In this configuration, the 3d subshell contains 8 electrons, with 2 of them unpaired. Therefore, a nickel atom has 2 unpaired electrons.
How many protons electrons and nuetrons in Sc-45?
Sc is a 3d element. It has 21 protons and 21 electrons.
Which element contains five electrons in its 3D orbital?
The element that contains five electrons in its 3d orbital is manganese (Mn). Manganese has an atomic number of 25, and its electron configuration is [Ar] 4s² 3d⁵. This means it has five electrons in the 3d subshell.
Why does an element lose 4S electrons before 3D electrons?
An element loses 4s electrons before 3d electrons because the 4s orbital has a higher energy level (n value) than the 3d orbital. When an atom loses electrons to form a cation, it tends to lose the electrons from the outermost shell first, which in this case is the 4s orbital.
