The immediate product of neutron absorption by Ag-107 is silver atom with a mass of 108, Ag-108.
<h3>What is radioactivity?</h3>
Radioactivity is the spontaneous emission of radiation as wall as particles and energy l by the nucleus of elements due to their disintegration.
The radioactive particles that are usually emitted include:
- alpha particles
- beta particles and
- neutrons
The neutron has a mass of 1.
When silver isotope having a mass of 107 absorbs a neutron, the silver isotope produces will have a mass of 108, Ag-108.

Answer: Noble-gas notation of Sn contains Kr.
Explanation: Tin ( Sn) is an element having atomic number 50.
Nearest noble gas to this element is Krypton which has an atomic number 36.
Electronic configuration or noble-gas notation for Sn is written as :
![Sn=[Kr]4d^{10}5s^25p^2](https://tex.z-dn.net/?f=Sn%3D%5BKr%5D4d%5E%7B10%7D5s%5E25p%5E2)
As seen from above, Noble gas Krypton having symbol 'Kr' is coming in the electronic configuration for Tin.
Out of the choices given, the one that describes a substance whose atoms all have the same number of protons are an element. The correct answer will be B.

Explanation:
The correct answer for the question that is being presented above is this one: "<span>16.728 g."</span>
Given that
ΔHsolid = -5.66 kJ/mol.
This means that 5.66 kJ of heat is released when 1 mole of NH3 solidifies
When 5.57 kJ of heat is released
amount of NH3 solidifies = 5.57/5.66 = 0.984 moles
<span>molar mass of NH3 = 17 g/mole </span>
<span>1 mole of NH3 = 17 g </span>
So, 0.984 moles of NH3 = 17 X 0.984 = 16.728 g
