[Kr] 4d10 5s2 5p4 is the noble gas configuration for telleurium because of the presence of different number of electrons.
<h3>What is telleurium?</h3>
Tellurium is a noble gas element that is non-reactive in nature due to complete outermost shell. It has atomic number of 52 which means that it has 52 number of electrons.
So we can conclude that [Kr] 4d10 5s2 5p4 is the noble gas configuration for telleurium because of the presence of different number of electrons.

Answer:
The mass of Mg consumed is 23.76 g.
Explanation:
Magnesium and nitrogen react as : three moles of magnesium reacts with one mole of nitrogen to give one mole of magnesium nitride.
as given that the mass of nitrogen reacted = 9.27 g
moles of nitrogen reacted =
Thus moles of magnesium reacted = 3 X 0.33 = 0.99 moles
mass of Mg reacted = moles X atomic mass = 0.99 X 24 = 23.76 grams
