Answer:red, orange, yellow, green, blue, indigo and violet.
Explanation:
Quantum states of electrons are usually written in terms of four numbers: the principle quantum number (n), the angular momentum azimuthal number (L), the magnetic quantum number (ml), and the spin projection number (ms). The quantum number set (4,1,0,+1/2) and (4,1,1,+1/2) share the same principle quantum numbers and therefore both sit in the n=4 electron shell.
Sn + CuSO4 → Cu + SnSO4 I think this should be the answer. Hope it helps.
I’m not sure if this will help, but protons make different elements. That’s how we can tell the difference between elements!
Well, after 1 half life, depending on whatever the amount is, 50% of the original content and or remaining content will undergo decay, as it is unstable.
Original content - 200g
1 half life - 100 g
2 half life - 50 g
3 half life - 25 g
The correct solution would be D. 25 g.
