That is Pb (Lead) All you need to do is look at he last orbital and find that on the periodic table!

Answer: Lead (Pb)

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The given element is a p block element as the last electron enters the p orbital. The nearest noble gas is Xenon with 54 electrons.

The electrons are filled according to Afbau's rule in order of increasing energies and the electronic configuration in terms of noble gs configuration is:  

[Xe]6s^24f^{14}5d^{10}6p^2

Total number of electrons = 54+2+14+10+2= 82

The element which has 82 electrons and thus the atomic number is 82, the element is lead with symbol Pb

Calculate the theoretical yield of glycolysis and complete glucose breakdown
rusak2 [61]
Eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH

The isomerization reaction, ch3nc → ch3cn, is first order and the rate constant is equal to 0.46 s-1 at 600 k. what is the conce
Harlamova29_29 [7]
According to this formula :
㏑[A] /[Ao] = - Kt 
when we have Ao = 0.3 m 
and K =0.46 s^-1
t = 20min = 0.2 x 60 =12 s
So by substitution :
㏑[A] / 0.3 = - 0.46 * 12
㏑[A] / 0.3 = - 5.52
by taking e^x for both side of the equation we can get [A]
∴[A] = 0.0012 mol dm^-3
