Updated on February 25, 2026
– The core electrons are those electrons which are in the inner shell of an atom that are near to the nucleus and valence electrons are those which are the outermost electrons that are the electrons present in the outermost orbit.
What is Mercury’s electron configuration?
[Xe] 4f14 5d10 6s2
Mercury/Electron configuration
What is number of core electrons?
Core electrons are the electrons in an atom that are not valence electrons and do not participate in chemical bonding. For transition metals, the number of valence electrons ranges from 3-12 electrons (ns and (n−1)d orbitals).
How many core electrons are in a chlorine atom?
10 core electrons
Chlorine has 10 core electrons. The number of core electrons equals the difference between the total number of electrons and the number of valence electrons, or 17 – 7.
What are core electrons examples?
Since these electrons reside at inner locations of the atom, the core electrons do not participate in bond formation. They reside in inner shells of an atom. For example, in a nitrogen atom (1s2 2s2 2p3), five electrons out of all seven are valence electrons, whereas two 1s electrons are core electrons.

Why is Mercury classified as a transition metal?
It is classified as a transition metal. Mercury atoms have 80 electrons and 80 protons with 122 neutrons in the most abundant isotope. Under standard conditions mercury is a shiny, heavy, silvery liquid.
What are the four orbital designations of mercury?
The four orbital designations are s, p, d and f. Mercury is a naturally occurring element commonly found in cinnabar. Mercury is a substance once thought to have alchemical properties, which resulted in the poisoning of several famous figures who did not understand its effects.
