- D
Explanation:
Those are the answers in order, BUT the Goldstein and Rutherford ones are confusing me because Rutherford discovered<em> protons</em> and the <em>nuclear atom</em>. Through my research I also noticed that Goldstein contributed to the discovery of the protons made Rutherford, so I listed him as the one who discovered the proton.
I hope this helps! Have a wonderful night! :D
Answer:
I’ll give you two possible conditions:
(1) An acid is present in an aqueous solution. The acid will donate a proton to the water to form hydronium. (That’s not really what happens, but that’s how we usually think of it.)
(2) The autoionization of water: in a pure water solution (or not a pure solution, doesn’t matter), one water molecule donates a proton to another water molecule, forming equal numbers of hydronium and hydroxide ions.
The largest energy release will take place when the electron jumps between the greatest number of levels. In this case from infinity down to 2
This is the emitted photon with the most energy ( in the Balmer series), the highest frequency and therefore the shortest wavelength.
Balmer's original formula was
Wavelength = 3645.6 . 10^–10 ( n^2 / (n^2 – 4) )
When n => infinity
Wavelength = 3.6456 . 10^–7 m ( or 364.5 nm)
You calculate the mass using dimensional analysis.
We are given with
The weight of the chain per unit length which is 2.16 kg/m
We are also given with the needed length of the chain which is 7.0 m
Therefore, the mass of the chain is
7.0 m x 2.16 kg / m = mass of the chain in kg<span />
Answer:
IODINE
Explanation:
The sublevel notation of the element:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁵
To find this element, we must add the powers of the each of the sublevels. This is the number of electrons in the orbital of the atom.
2 + 2 + 6 + 2 + 6 + 2 + 10 + 6 + 2 + 10 + 5 = 53
This give atom has 53 electrons and we can assume it to have an atomic number of 53.
The element is IODINE
