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.

Answer:
2.5 grams
Explanation:
law of conservation of mass applies. the magnesium completely burns
Answer:
Zirconium, Zr, 40
Explanation:
Protons can be found by looking at the atomic number. Neon's atomic number is 10, so just multiply 10 by 4 and you get 40.
They have different number of neutrons.
<span>Combining radiation therapy with other treatments. Chemo radiation is when chemotherapy and radiation therapy are used together. Chemo radiation is used to treat many cancers. Giving chemotherapy at the same time as radiation therapy improves the effects of radiation on cancer cells</span>
