Eu2+ is stable because of the two electrons in its outermost orbit and after losing 4 electrons. Ce +4 is stable
What are lanthanide ions?
All lanthanide elements form trivalent cations, Ln3+, whose chemistry is largely determined by the ionic radius, which decreases steadily from lanthanum to lutetium. These elements are called lanthanides because the elements in the series are chemically similar to lanthanum.
The Ce metal has the following electronic configuration: [Xe] 4f¹5d¹6s²
It obtains noble gas configuration after losing 4 electrons. Ce +4 is stable, so.
Eu's electronic setup is as follows.
[Xe] 4 f ⁷6s²
[Xe] 4 f ⁷
Eu2+ is stable because of the two electrons in its outermost orbit. Additionally stable is its +3 oxidation state. Ce⁺²

Answer:
V = 44.83 L
Explanation:
Given data:
Mass of fluorine = 76 g
Temperature = 0°C (0°C + 273 = 273 K)
Pressure = 101.3 Kpa ( 101.3 / 101 = 1 atm)
Volume of fluorine = ?
Solution:
Number of moles of F = Mass/ molar mass
Number of moles = 76 g/ 38 g/mol
Number of moles = 2 mol
Volume of fluorine:
PV = nRT
V = nRT/ P
V = 2 mol × 0.0821 atm. L/ mol. k × 273 k / 1 atm
V = 44.83 L. atm / 1 atm
V = 44.83 L
Answer:
A Bunsen bumper,named after Robert Bunsen, is a kind of gas burner used as laboratory equipment;it produces a single open gas flame ,and used for heating ,sterilization,and combustion. The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas,such as propane,butane,or a mixture
