Answer:
c. offers a great deal of network control and lower cost.
Explanation:
A network topology can be defined as a graphical representation of the various networking devices used to create and manage a network.
Compared with a star topology, a hierarchical topology offers a great deal of network control and lower cost.
The answer to this should be B. Worm. A pinion is a the smallest gear out of the listed ones above. spur would be next then wheel and the biggest if them all would be the spur. I'm not completely sure if my answer is 100% correct, but I feel confident enough about it. Hope this helps. :)
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
