Answer:
(edit: nvm I figured it out, here is the answer)
Explanation:
Protons: 12
Neutrons: 13
<span>Electrons: 12</span>
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
hope this helps you
have a nice day:)
Answer: (a) BE = 1.112 MeV
(b) BE = 7.074 MeV
(c) BE = 7.767 MeV
(d) BE = 8.112 MeV
Explanation: Binding energy per nucleon is the average energy necessary to remove a proton or a neutron from the nucleus of an atom. It is mathematically defined as:

Where
Δm is a difference in mass known as <u><em>mass</em></u><em> </em><u><em>defect</em></u>
A is atomic mass of an atom.
Mass Defect is determined by:

where:
Z is atomic number
is mass of proton
is mass of neutron
is mass of the nucleus
Mass of proton is 1.007825u.
Mass of neutron is 1.008665u.
The unit u is equal to 931.5MeV/c².
(a) 2H(deuterion): Given: Z = 1; A = 2;
= 2.014102u



BE = 1.112MeV
(b) 4He (Helium): Given: Z = 2; A = 4;
= 4.002603



BE = 7.074MeV
(c) 18O (Oxygen): Given: Z = 8; A = 18;
= 17.999160



BE = 7.767MeV
(d) 23Na (Sodium): Given: Z = 11; A = 23;
= 22.989767



BE = 8.112MeV
