<h2>Aspect of The Modern Model </h2>
Following is the one aspect of the modern model of the atom that agrees with a conclusion made by Thomson as following:
- Atom is a neutral particle.
- The number of electrons and protons are always equal in an atom according to their atomic number.
- Atomic number is the number of protons in an atom.
Answer:
Intermolecular
Explanation:
Intermolecular forces are the forces operating between the two molecules. These forces are of short rang forces and also known as week intermolecular forces.
These forces only exist when molecules get close together by force of by cooling.
Example:
Hydrogen bond (intermolecular forces) exist in liquid water molecules but when we heat it the water molecule escape from surface by as hydrogen bond break by heating.
Compressed Natural Gas:
In this case the molecules of natural gas presses and the come closer so the distance between the molecules become less and force of attraction increase that attraction (intermolecular force ) is due to short distance.
When placed in an electrical field, the negative charge found in the sugar-phosphate backbone of DNA polymers cause them to migrate towards the positive electrode.

I'm taking the test right now; I'll edit this when I find out if I was right! (I chose "solvent" but I wanna be sure.)
Edit: Solvent is the correct answer!
Protons and Neutrons are the same size and have the same mass (1Amu)
If you notice, atomic mass is protons + Neutrons.
The mass of an electron is so small that it is often neglected in terms of calculations.
B electrons is the answer
