answer:4
The electron configuration "Ra 7s² 5f³" is not valid because it incorrectly places electrons in the 7s subshell for an atom that should not have electrons in that energy level. Radium (Ra), with an atomic number of 88, has its valence electrons in the 7s subshell, but the 5f subshell can only accommodate 14 electrons in elements of the actinide series. The correct configuration for radium is [Rn] 7s², and the 5f subshell is filled in elements like actinium (Ac) and beyond.
32 inches = 81.28 centimeters.
Answer: 180 inches is equivalent to 15 32 feet
There are 32 32nds of an inch in one inch.
1.3 Liters
5.28751 7s equals 37.
32 - 21 = 11
To find how many 7s are in 93, you can divide 93 by 7. When you do this calculation, 93 ÷ 7 equals approximately 13.29. This means there are 13 full 7s in 93, with a remainder.
