Cu has an anomalous electron configuration. write the observed electron configuration of cu.

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.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
