If you are sure it is Ti (not Tl) then following will work:-
Ba, Ti, Sb, As, S
But before entering this answer make sure it is really Ti. If not, answer will be different. Ti is titanium and Tl is thallium.

I analyzed just now. Correct answer is
Ba, Tl, Sb, As, S
If it is Ti, then also order will be same. Just replace Tl by Ti.

hey! i need helo in chemistry. the ques is something like:

What is the azimuthal quantum number, l, for the orbital shown here?
Express answer numericaaly as an integer.BLB-1076861-orbital2.jpg

Answer: 2
Reason: The shape shows that it is d-orbital and d-orbitals have l = 2

Compare the orbital shown in Part A to the orbital shown here (Part B figure) in size, shape, and orientation. Which quantum number(s) would be different for these two orbitals?

n only
l only
ml only
l and ml
n, l, and ml
The figure is shown below
BLB-1076861-orbital1.jpg
Answer: ml only
Reason: ml tells orientation. The two orbitals are both d-orbitals, so they will have same l but they have different orientations, so different ml.

[How would the dx^2-y^2 orbital in the n=5 shell compare to the dx^2-y^2 orbital in the n=3 subshell?

    a)The contour of the orbital would extend further out along the x and y axes.
    b)The value of l would increase by 2.
    c)The radial probability function would include two more nodes.
    d)The orientation of the orbital would be rotated 45degree along the xy plane.

e)The ml value would be the same.

We have to find which statement is true and which is false


a. True (When n increases then you have electrons in orbitals that can have probability densities that are further distances from the nucleus.)

b. False (All d orbitals have l=2)

c. True
(Formula: Number of radial nodes = n-l-1. 3d orbital has n=3,l=2, therefore n-l-1=3-2-1 = 0. 5d orbital has n=5, l=2, therefore n-l-1 = 5-2-1 = 2)

d. False (All dx^2-y^2 have two dumbelss, one along x axis and the other along y axis)
e. True (ml value depends on the orientation. Since they have the same orientation, they will have the same ml value)
