Answer:
Oxygen molecule is 2 oxygen atoms in a covalent bond, whereas an oxygen atom is an atom with 8 electrons (6 valence electrons).
Thus, clearly, any element in a bonded state is always more stable than when in an un-bonded state.

Answer:
Explanation:
The Ce metal has electronic configuration as follows
[Xe] 4f¹5d¹6s²
After losing 4 electrons , it gains noble gas configuration ,. So Ce ⁺⁴ is stable.
Eu has electronic configuration as follows
[ Xe ] 4 f ⁷6s²
[ Xe ] 4 f ⁷
Its outermost orbit contains 2 electrons so Eu²⁺ is stable. Its +3 oxidation state is also stable.
Ce⁺²
Normal boiling point is 99.97 degrees C and 211.9 degrees ferinhight. And a pressure of 1atm or 101.325 kPa. Hope this helps :)
When mass Ti = density * volume
and when moles Ti = mass Ti/molar mass Ti
∴ Volume = 2.86 x 10^23 atom * ( 1 mol Ti / 6.022 x 10^23) * (47.867 g Ti / 1 mol Ti) *(1Cm3 / 4.5 g Ti )
= 5.05 Cm^3
when we assume that the sample of Ti is a cube:
and we assume the length = X
∴ V = X^3
∴X^3 = 5.05
∴X = ∛5.05
= 1.7 Cm
