Cu has an anomalous electron configuration. write the observed electron configuration of cu.
2 answers:
Explanation:
Atomic number of copper is 29 and it is a d-block element.The electronic configuration of copper is as follows.
Electronic configuration of copper is
According to the Aufbau principle, in the ground state of an atom or ion the electrons fill atomic orbitals of the lowest energy levels first, before filling the higher energy levels.
But completely filled d-shell is more stable in nature. Hence, one electron from the 4s shell goes into the d-orbital so the copper atom can attain stability.
So, when a copper atom loses an electron then it goes out from the 4s shell first.

Answer:
0.37atm
Explanation:
Given parameters:
Initial pressure = 0.25atm
Initial temperature = 0°C = 273K
Final temperature = 125°C = 125 + 273 = 398K
Unknown:
Final pressure = ?
Solution:
To solve this problem, we use a derivative of the combined gas law;
=
P and T are pressure and temperature
1 and 2 are initial and final values
=
P2 = 0.37atm
Answer:
50 MHz
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Wavelength = 6 m
Thus, Frequency is:
Also,
Also, 1 Hz = MHz
So,<u> Frequency = 50 MHz.</u>
