During osmosis, water moves from a region of _____ to a region of _____.both "high solvent concentration; low solvent concentrat
Vinil7 [7]

Answer: -

Osmosis is the process by which water molecules move from a region of high solvent concentration to low solvent concentration.

Now in any solution there are just solute and solvent.

If the amount of solvent is more in a solution then the amount of solute would be less.

Again if the amount of solvent is less in a solution then amount of solute is more.

Thus we can write that :- osmosis is the movement of water molecules from a region of low solute concentration to high solute concentration.

What is the ground state electron configuration for Ru2+?
Natali5045456 [20]

Electronic configuration: The distribution or arrangement of electrons of a molecule or an atom in molecular or atomic orbitals.

Ground state electron configuration: The distribution of electrons of an atom or molecule around the nucleus with lower levels of energy.

Now, Ru stands for Ruthenium with atomic number 44. It is a metal and thus, has ability to lose electrons and, becomes positively charged ion.

One can write the electronic configuration with the help of atomic number and Afbau principle, Pauli exclusion principle etc.

Ground electronic Configuration is as follows:

Ru = s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{1}4d^{7}

Soft Hand notation: [Kr]4d^{7}5s^{1}

Now, when ruthenium loses two electrons then it becomes Ru^{+2}, thus electron configuration becomes

Soft Hand notation: [Kr]4d^{6}

The ground state electronic configuration of Ruthenium is [Kr]4d^{7}5s^{1} and when it loses two electrons, then electronic configuration becomes [Kr]4d^{6} ( Ru^{+2})
