Answer is: the amu of a sodium atom is 23.
The unified atomic mass unit (amu) is a standard unit of atom mass.
One unified atomic mass unit is approximately the mass of one nucleon (proton or neutron).
The unified atomic mass unit is equal 1.66·10⁻²⁷ kg.
n(p⁺) = 11; number of protons in sodium atom.
n(n°) = 12; number of neutrons of sodium atom.
n(p⁺ + n°) = 11 + 12.
n(p⁺ + n°) = 23; number of nucleons in sodium atom.
Answer:
Explanation:
Nitrogen has the atomic number = 7
So, No. of electrons = 7
<u><em>Electronic Configuration:</em></u>

Answer:
none of the above
Explanation:
A system is said to have attained dynamic equilibrium when the forward and reverse reactions proceed at the same rate. That is;
Rate of forward reaction = Rate of reverse reaction
The implication of this is that the concentrations of reactants and products remain constant when dynamic equilibrium is attained in a system. This does not mean that the reactant and product concentrations become equal; it rather means that their concentrations do not significantly change once dynamic equilibrium has been attained.
