Core electrons are typically lower in energy compared to valence electrons. This is because core electrons are closer to the nucleus and are more tightly bound due to the stronger electrostatic attraction from the positively charged nucleus. In contrast, valence electrons are farther away and experience greater shielding from the nucleus by the core electrons, resulting in higher energy levels. Consequently, valence electrons are more involved in chemical bonding and reactivity.
The energy is higher.
Valance electrons. When you get to core electrons the ionization energy is extremely high and found under plasma conditions.
Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
Core electrons generally have lower energy compared to valence electrons. This is because core electrons are closer to the nucleus and are more tightly bound due to the stronger electrostatic attraction to the positively charged protons. In contrast, valence electrons, being farther away and experiencing greater shielding from the nucleus, possess higher energy levels and are more involved in chemical bonding and reactions.
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
The energy of the valence electrons is greater than the energy of the core electrons.
The energy is higher.

The energy of the valence electrons is greater than the energy of the core electrons.
Core electrons have lower energy levels than valence electrons. Core electrons are closer to the nucleus and are more tightly bound, while valence electrons are in the outermost energy level and have higher energy due to being farther from the nucleus.
The energy is higher.
Core electrons have lower energy compared to valence electrons. Core electrons are located closer to the nucleus, experience a higher effective nuclear charge, and are more shielded by inner electron shells, leading to lower energy levels. Valence electrons are found in the outermost energy level and have higher energy due to their increased distance from the nucleus and lower shielding effect.

Helium has 2 core electrons. This is because it has 2 electrons in the innermost energy level (K shell), which are considered core electrons.
