As a general rule yes, larger molecules do tend to have more neutrons than protons.

Are neutrons smaller than protons?
no, they both have the same relative mass, this is why you add the number of protons and neutrons to get the mass number for the atom. The neutron is very slightly more massive than proton, by about the mass of an electron.
Why do atoms of heavier elements generally contain more neutrons than protons?
because the protons and electrons HAVE to cancel out each other and ive knowtest that normally, there are around 1/2 as many neutrons then protons.
When 2 hydrogen nuclei fuse do they make helium?
No, an element depends on the average amount of electrons it has. Actually in stellar nuclear fusion it takes 4 hydrogen nuclei to fuse to make one helium nucleus, the process is called proton-proton burning.
What are the relative atomic mass of subatomic particles in atom?
neutrons are heavier than protons by a bit more than the mass of electron.
What are the names of 2 nucleons?
The particles found in the nucleus are collectively called nucleons. Nucleons are protons and neutrons.
What does the nuclei of heavy atoms have that light atoms do not have?
The nuclei of heavier atoms simply have more neutrons and protons than do lighter atoms.
Where does the weight of the nucleus mostly come from?
The nucleus is made up of protons and neutrons. Most of the elements with low atomic numbers are equally protons and neutrons. However, as elements get heavier they will have more neutrons than protons, and since each weigh the same amount (1 atomic mass unit) these nuclei will get most of their weight from the neutrons.
What do a heavy nuclei need to remain stable?
More neutrons than protons.
Why is fluorine heavier than nitrogen?
the number of neutrons and protons are more.
Lighter elements have more or less number of protons than neutrons?
Lighter elements tend to have neutrons equal to protonms or only a slight excess. Heavier elements have an excess of neutrons over protons

What is an isotone?
Isotopes are atoms of the same element with different numbers of neutrons, but the same number of protons.
Why does atom of different elements weigh differently?
Every element has a specific amount of protons and neutrons in its nuclues. If an atom has more protons and neutrons than another element, it is heavier.
Which of the following nuclei would be the most stable A. 10 protons , 14 neutrons B. 10 protons, 15 neutrons C. 10 protons, 13 neutrons D. 10 protons, 12 neutrons.?
(Explanation): remember that if an atom has less than 20 protons, the closer the number of neutrons and protons are, the more stable it is. Since 10 is closest to 12 out of these options, D is the correct answer.
Why there are many neutrons than protons in metal atom?
I assume you mean "more neutrons than protons". It really depends what metal you are talking about. The lightest metal is lithium; it has 3 protons. One of its naturally occurring isotopes has 3 neutrons, another has 4 neutrons. In the case of heavier elements, the ratio of neutrons to protons increases; this is not directly related with the elements being "metals", just with the fact that they are heavier elements. The general idea here is that for heavier elements, the repulsive forces between protons become larger; more neutrons are then needed to provide stability, since protons and neutrons attract one another using the strong force, but don't have an electrostatic repulsion.
How does the ratio of nuetrons to protons for the stable nuclei change as atomic number increases from 1 to 82?
because it becomes more complex and the nuclei has to mange more neutrons Sources: Science Teacher
