What is an inner core in chemistry?

What you read somewhere probably refers to the electrons in an atom that are not valence electrons and therefore do not participate in bonding (core electrons). My English is not good enough when it comes to the technical (or scientific) terms. read more

Video: Inner Core of the Earth: Definition, Composition & Facts The inner core is located at the center of the Earth and is composed of nickel and iron. Most of what we know about the inner core is through studying seismic waves. read more

What you read somewhere probably refers to the electrons in an atom that are not valence electrons and therefore do not participate in bonding (core electrons). My English is not good enough when it comes to the technical (or scientific) terms. But the inner core should refer to the portion of atoms that do not participate in the reaction / bonding. read more

Inner core electrons do have a very strong affect on the chemistry of elements,for example inner d orbitals have a very poor shielding effect thus the outer electrons are bounded more strongly to the nucleus thus decreasing their reactivity and oxidation states.You will come across inert pair effect,stability of lower oxidation states down the group etc because of effect of inner core electrons. read more
