I think the answer is teh first choice. Cockroaches can live through atomic radiation!
Answer:
The difference between the two is:
![[Kr]4d^1^05s^25p^2](https://tex.z-dn.net/?f=%5BKr%5D4d%5E1%5E05s%5E25p%5E2)
is the Orbital Occupancy
![[Kr]5s^24d^1^05p^2](https://tex.z-dn.net/?f=%5BKr%5D5s%5E24d%5E1%5E05p%5E2)
is the Orbital Filling Order
Both are correct, I don't think your teacher will be so nit-picky to care.
The balanced chemical reaction is written as:
<span>2K + F2 ---> 2 KF
We are given the amount of potassium metal to be used in the reaction. This will be the starting point for the calculation. We do as follows:
23.5 g K ( 1 mol / 39.1 g ) ( 1 mol F2/2 mol K ) ( 22.4 L / 1 mol ) = 13.46 L F2

Answer:
Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
