Yes, it is easier to remove a core or a valence electron from an atom.

Valence electrons are the furthest from the positive charge (protons) and therefore also appear to be easier to remove than core electrons this signifies that electrons need less energy to transfer out from the atom. Electrons orbit around a nucleus in orbitals.

Quantum mechanics determines these orbitals and the energy required to remove each electron from the atom. Each of these orbitals helps to form an electron shell in the atom. Valence electrons are electrons in an atom's outermost atomic shell that circle the nucleus.

Closer to the nucleus, electrons are in filled orbitals and are referred to as core electrons. This distinction is due to the fact that electric force is an inverse square law. Furthermore, inner shell core electrons have lower energy levels than outer shell valence electrons. This means that electrons in the inner shells can absorb energy and migrate (jump) to the outer shells.

What is the mass of 2.1 moles of the hydrate Nickel (II) carbonate pentahydrate (NiCO3 x 5H2O)?
kifflom [539]

The  mass of 2.1 moles of the hydrate Nickel (II) carbonate pentahydrate NiCO3 x 5H2O 773.5 grams.

<h3>What are moles?</h3>

Mole is the smallest particle of atom which is equal to the Avogadro's number which is 2.303 × 10²³moles of an atom and can be calculated by,

             

          number of moles = mass of mole / molar mass of the mole.

            mass = 2.1 moles

            molar mass of NiCO3 x 5H2O = 368.38

Substituting the value in the formula,

2.1 mole = mass of mole / 368.38

mass of mole = 773.59 grams.

Therefore, mass of 2.1 moles of the hydrate Nickel (II) carbonate pentahydrate NiCO3 x 5H2O 773.5 grams.
