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
Answer:
The answer is "Remote access
"
Explanation:
The capacity to access another computer or network that you do not have. Remote computer access provides an employee with remote access to the desktop and file. This assists an employee, for example, who works at home efficiently.
Remote users access documents or other resources on any network-connected device or server, enhancing organizational efficiency and increase there are to cooperate more interact with peers nation.
Answer:
The answer is "Option (i)".
Explanation:
- In the given question, an array is defined. It is a collection of the same type of data element, which means, array stores either a numeric value or string value at a time.
- An array beta is defined, which contains 50 elements. The array elements indexing always starts with 0 which means, the first element of the array will be stored in an index value that is 0. That's why option (i) is correct.
