La temperatura es un cambio físico
That water is a universal solvent and that sugar is soluble?
Answer is: Sb(g) → Sb⁺(g) + e⁻.
Neutral atom in gas state lose one valence electron and become cation with postive charge.
<span>The first ionisation energy is the energy required to remove one mole of the valence electrons from one mole of gaseous atoms to produce one mole of gaseous ions each with a charge of 1+.</span>
<span>Most metals have strong
metallic bond, because strong electrostatic attractive force
between valence electrons (metals usually
have low ionization energy and lose electrons easy) and positively
charged metal ions.
