Answer:
-
= 1
= 1
Explanation:
Argon atom has atomic number 18. Then, it has 18 protons and 18 electrons.
To determine the quantum numbers you must do the electron configuration.
Aufbau's principle is a mnemonic rule to remember the rank of the orbitals in increasing order of energy.
The rank of energy is:
1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s < 4d < 5p < 6s < 4f < 5d < 6p < 7s < 5f < 6d < 7d
You must fill the orbitals in order until you have 18 electrons:
- 1s² 2s² 2p⁶ 3s² 3p⁶ : 2 + 2 + 6 + 2 + 6 = 18 electrons.
The last electron is in the 3p orbital.
The quantum numbers associated with the 3p orbitals are:
- = 1 (orbitals s correspond to = 0, orbitals p correspond to = 1, orbitals d, correspond to = 2 , and orbitals f correspond to = 3)
- can be -1, 0, or 1 (from - to + )
- the fourth quantum number, the spin can be +1/2 or -1/2
Thus, the six possibilities for the last six electrons are:
- (3, 1, -1 +1/2)
- (3, 1, -1, -1/2)
- (3, 1, 0, +1/2)
- (3, 1, 0, -1/2)
- (3, 1, 1, +1/2)
- (3, 1, 1, -1/2)
Hence, the correct choice is:
- = 1
- = 1

Explanation:
<u>DC Circuit</u>
The DC circuit shown it the figure has a power source (battery), some resistors, switches and voltage and current meters. The switch S1 is open, so the right branch of the circuit is neglected. Assuming all meters are ideal (no resistive losses), we have a simple series circuit made of resistors R2 and R3.
We are required to compute the total power dissipated in the circuit, which corresponds to the total power delivered by the voltage source.
The power source of V= 6V is delivering a current in the series circuit equal to the current through R1 and R3. That current is the same as that read by M1 known to be I=0.04 A
The power delivered by the source is
D, gather evidence, it’s obvious he should have reported the problem which as many evidence possibly found, instead decides to reboot the server.
