Chemisty Question please help???

Question

which element may react chemically by losing electrons from both s and d sublevels?
1.Cl
2.Fe
3.Al
4.Be

Answer 1

Should be Fe..This is the only transitional element in the list..It's the only element with electrons in the d orbital..

Answer 2

The only transitional metal in the list is Iron so that is the correct answer.

Iron would lose two electrons from its s orbital before it lost any from its d orbital. Losing two electrons would give its cation a +2 charge. If it then lost another electron from the d orbital it would have a charge of +3.

It would tend to only lose one electron from its d orbital as it would then have five electrons in the d orbital, all unpaired, which is a stable half pseudo nobel gas configuration for transitional metals.

The thing that most chemistry texts don't mention is that the order that electrons fill the orbitals for transitional metals is usually NOT the order that they are lost to form cations. Der Aufbau works for describing the order electrons are gained but not for the order they are lost.

Answer 3

If team chemistry did not make the gang greater advantageous and it replaced into purely in step with skills then does not communities like Denver (in the previous the commerce) be the appropriate interior the NBA? investigate the Cavs. Do you think of without chemistry that they had nonetheless have the appropriate checklist interior the NBA? reason as a fan, i be attentive to i don't. It makes you play greater advantageous when you consider which you be attentive to you may believe your teammates, and you something interior you purely connects on the courtroom. this is stressful to describe, yet i be attentive to this is had to fulfillment.

Answer 4

Mack b sorry to tell you but Cl does not even have d sublevels.

Answer 5

Only iron can, as is observed in the ferric (Fe3+) ion.

Answer 6

chlorine...cuz its the only one i no.
