Br- < Se2- < As3- < Sr2+ < Rb+
I hope this helps although I'm not a hundred percent sure!
Answer:
A. 2.4 x 10¹⁴ J
Explanation:
m (mass) = 2.7 x 10⁻³ kg
c = 3.0 x 10⁸ m/s
Plug these numbers into the equation E=mc²
E=mc²
E= (2.7 x 10⁻³)(3.0 x 10⁸)²
E= 2.43 x 10¹⁴
So, the answer is A. 2.4 x 10¹⁴ J.
Answer:
Lead atoms have 82 electrons and the shell structure is 2.8. 18.32. 18.4.
Explanation:
The ground state electron configuration of ground state gaseous neutral lead is [Xe].
I would say A,B and D. The spectra allow for the determination of isotopic signatures of samples, the masses of particles and of molecules and thus the density, and most likely the energy levels of atoms. The energy given off by the elements allow these qualities and quantities to be determined.
Answer:
A spinning ball creates a "Centrifugal Force" because you give it the "energy" to spin. A ball that is not moving does not require any external energy to keep it still.
