four quantum numbers that could represent the last electron added (using the Aufbau principle) to the Argon atom. A n = 2, l =0,
marshall27 [118]

Answer:

  • n = 3
  • l  = 1
  • m_l = 1
  • m_s=+1/2

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:

  • n = 3

  • l = 1 (orbitals s correspond to l = 0, orbitals p correspond to l  = 1, orbitals d, correspond to l  = 2 , and orbitals f correspond to  l = 3)

  • m_l can be -1, 0, or 1 (from - l  to + l )

  • 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:

  • n = 3
  • l  = 1
  • m_l = 1
  • m_s=+1/2

when using screwdrivers you should always be aware that the screwdriver blade might slip out of the slot and strike you in the .
ELEN [110]

When using screwdrivers you should always be aware that the screwdriver blade might slip out of the slot and strike you in the:

  • -hand
  • -eye
  • -mouth

<h3>What is a Screwdriver?</h3>

A screwdriver is said to be a kind of a modern tool that can come in a manual or powered type and it is one that is often used for turning screws.

Note that a typical simple screwdriver is one that has a handle as well as a shaft and it is also one that is often ending in a tip where a given user can be able to put their hands into the screw head before turning the handle.

Therefore, when using screwdrivers you should always be aware that the screwdriver blade might slip out of the slot and strike you in the:

  • -hand
  • -eye
  • -mouth

How do nations mostly use technology in foreign relations? Check all that apply.
Andreas93 [3]

Answer:

  • to spy on one another
  • to carry out cyber attacks
  • to improve their public images

Explanation:

Different countries have tools to hack, control and filter information in foreign countries using different devices and techniques that allow them to be aware of any threat that may arise from another country, as well as obtaining information that helps them.

By linking technology with foreign policy, it is possible to strengthen and complement national capacities in these areas, opening the possibility of diversifying and expanding the projection of a country with an excellent image that offers sophisticated technology-based services.
