Considering that scientific notation has to move the decimal over so there is only one digit in the Tens place, that is the scientific notation.
Answer:
1 mole of water and 6.022 ×10^23 water molecules
Answer:
if it cannot be made to fit the new findings
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
