please answer 19-28
Quantum mechanics is a very complex theory. A good way to help you remember it is to compare it to an apartment building, An apartment building has different floors, different apartments on each floor, and different rooms within each apartment. We can look upon the electrons of an atom as rather peculiar apartment dwellers. Electrons prefer the floor closest to the ground and the smallest apartments. Electrons also prefer to live one to a room until each room in an apartment has one occupant. The electrons will then pair up until each room has two. Each room in an apartment can hold two electrons Apartment buildings have several floors. The model we discuss has several floors, but only the first 7 floors will be occupied. All the electrons known today will fit within 7 floors of the building. Additional floors are available but will only be occupied in special situations. The floors in the apartment building are called shells in the electron model and are numbered 1-7.1) According to what you have just read, what shell will be occupied first by electrons?2 Flers Each shell (or floor) in the model has one or more apartments, which are called subshells. These subshells are apartments of four sizes: s,p,d, and f. An s subshell (apartment) has only a single room. A p subshell bas 3 rooms. A d subshell has 5 rooms, while an fsubshell has 7 rooms. An s subshell then will hold a maximum of 2 electrons according to the model. 2) A p subshell will bold a maximum of how many electrons? electioExplanation / Answer
Ans 1 : 1 floor
The filling of electrons occur according to the energy levels. The lower energy shells fill up first and the highest energy shells fill up at the last.
Ans 2 : 6 electrons
Since p subshell has 3 rooms , and each room can accomodate maximum of 2 electrons , the total electrons in p subshell will be 6.
Ans 19 : 18 electrons
Third shells has s , p and d subshells. So the total number of electrons present in it will be 2 + 6+ 10 = 18 electrons.
Ans 20 : s,p,d,f
The number of subshells can be determined by the principal quantum number. So all the shells numbered from 4 to 7 have four subshells in them.
