Tungsten (W) has an atomic number 74
The nearest noble gas to tungsten in the periodic table is Xe which has atomic number of 54.
Therefore, the configuration of W using the noble gas Xe will be as follows:
<span>[Xe] 4f14 5d4 6s2</span>
1) Balanced chemical reaction: Cl₂ + 2NaI → 2NaCl + I₂.
Chlorine and iodine are diatomic molecules.
2) Balanced chemical reaction: 2NH₃ → N₂ + 3H₂.
Nitrogen and hydrogen are diatomic molecules.
3) Balanced chemical reaction: 4Na + O₂ → 2Na₂O.
Sodium in compounds has oxidation number +1 and oxygen -2.
The best answer would be yes because some of the old ones will give a "boost" to the new ones that come in. Hope this helped!
