There are eight hydrogen atoms in the following molecule of ammonium sulfide. Thus, the correct option for this question is C.
A molecule may be defined as a cluster of atoms that are significantly bonded together in order to represent the smallest basic unit of a chemical compound that can involve in a chemical reaction.
According to this question, the correct representation of ammonium sulfide is , where the number of the hydrogen atoms is equal to 4 × 2 = 8. Apart from this, the number of nitrogen atoms is 2. While the number of sulfur atoms is only 1.
Therefore, there are eight hydrogen atoms in the following molecule of ammonium sulfide. Thus, the correct option for this question is C.

1) The binding energy per nucleon is 7.59 MeV/nucleon and 2) The binding energy per nucleon is 8.39 MeV/nucleon.
1) The binding energy per nucleon is as follows:
m_proton + m_neutron + m_electron - m_U
= 92*1.007276466812 + 92*5.4857990943e-4 + 143*1.008664916 - (235.0439299)
= 1.9151 u
= 931.494061 * 1.9151 MeV
= 1784 MeV
= 1784/235 = 7.59 MeV/nucleon
2) The binding energy per nucleon is as follows:
m_proton + m_neutron + m_electron - m_Cs
= 55*1.007276466812 + 55*5.4857990943e-4 + 82*1.008664916 - (136.9070895)
= 1.2338 u
= 931.494061 * 1.2338 MeV
= 1149 MeV
=1145/137 = 8.39 MeV/nucleon

the answer is ionic bonds
Answer:
Explanation:
The notation of the most common isotope of silicon is:
The superscript, 28, to the left of the chemical symbol, Si, is the mass number, usually identified with the symbol A, and it is the sum of the protons and neutrons.
The subscript, 14, to the left of the chemical symbolr, Si, is the atomic number, Z, which is the number of protons.
Then, you have this equation:
The number of protons is the same for any isotope of the same element. This is, all the isotopic forms of silicon have the same number of prtons: 14
The number of neutrons is determined from the equation A = Z + N, solving for N:
Hence, the most common isotope of silicon has 14 protons and 14 neutrons.
