Drag The Appropriate Items To Their Respective Bins. [Solved]

Question 1

I need the answer with molecular orbitals diagrams

Classify each of these ions as diamagnetic or paramagnetic.

Drag the appropriate items to their respective bins.

Ni^2+ Zn^2+ Cu^2+ Co^2+

Transition metal magnetism

Transition metals are sometimes magnetic, depending on the arrangement of their electrons. Most of them have unpaired electrons, which are required for paramagnetic behavior. If all of the electrons are paired up, then the ion will be diamagnetic.

Question 2

Drag The Appropriate Items To Their Respective Bins.

Question 3

Drag The Appropriate Items To Their Respective Bins.

Question 4

Drag The Appropriate Items To Their Respective Bins.

Answer to question 1

The transition metal ions usually promote their valence shell s electrons into the d orbitals, which explains the electron counts below.

Ni(II) has 8 electrons in its 3d orbitals. This means that 3 of the 5 orbitals are paired up, but the remaining 2 are unpaired, making Ni(II) paramagnetic.

Zn(II) has 10 electrons, which completely fill the d orbitals, so it’s diamagnetic.

Cu(II) has 9 electrons, which means that one must be unpaired, hence its paramagnetic.

Co(II) has 7 electrons, so like Cu(II) it must also be paramagnetic.

Answer to question 2

Step 1

Ionic compounds are formed by the electrostatic force of attraction between cation and anion. Metal and non-metal combine to form ionic compound.

Molecular compounds are formed by sharing of electrons between two similar or different element having small electronegativity difference.Usually two non-metal combine to form molecular compound.

Step 2

Answer to question 3

A group of sexually compatible inter-breeding individuals.

Gene pool: 
The sum of all genes in a population
The source of genetic information from which the next generation is produced.

Neither of two:
A group of individuals of different species = Community
The sum of most common genes in a population =?
