Answer: The correct answer is Option B.
Explanation: The compound given to us is . To write the IUPAC name for this compound, we need to follow some rules:
1. First write the name of the cation with its oxidation state in roman numbers.
2. Then write the name of the anion which may be a polyatomic ion or a non-metal.
3. The anion is used with a suffix '-ide'. Example: For chlorine, the anion would be named as chloride, for sulfur, the anion would be sulfide.
For the given compound, 2 silver atoms are needed to neutralize the charge on 1 sulfur atom.
Hence, the oxidation number of silver atom is '1'. So, the IUPAC name for the compound will be silver (I) sulfide.
Therefore, the correct option is B.
Permeability
Ductility
Not able to conduct heat
(2) absorb protons (4) oxidize
Answer: The nucleus of radium-226 is unstable and hence undergoes decay.
Explanation: Radium has many isotopes. One of them is which has 88 protons and 138 neutrons. It is a radioactive isotope and undergoes decay process.
This isotope undergoes alpha - decay and produces Radon-222 isotope.
Equation for alpha - decay follows:
Hence, the nucleus of radium-226 undergoes decay process.
Its atoms contain 50 electrons and 70 neutrons
Express your answer as an isotope.
