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.

What is the composition of lighter elements in comparison with heavier element?
The lighter elements have less protons and neutrons than heavier ones. It really is as simple as that
Does there have to be the same number of protons and neutrons in the nucleus?
No. Even atoms of the same element will vary in the number of neutrons in their nucleus. For example, carbon (6 protons) has isotopes with 6, 7, and 8 neutrons. The most common isotope of hydrogen (1 proton) does not have any neutrons. While the most common isotopes of the lighter elements generally have the same number of protons and neutrons, heavier elements will have more neutrons than protons. For example the most common most stable isotope of uranium (92 protons) has 146 neutrons.
Do atoms also contain neutrons which are slightly heavier than protons but carry no charge?
Yes it is very true
The source of fuel for fission reactors is?
"Binding energy." Absorption of neutrons by heavy elements, and fission of those heavy elements into lighter "fragments". The "lighter fragements" have a greater net binding energy than the heavier elements did.
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Do atoms have neutrons in them?
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.

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.
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

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.
Do atoms also contain neutrons which are slightly heavier than protons but carry no charge?
Yes it is very true
Why are some atoms are heavier than others?
some atoms are heavier than others as they have higher relative Atomic Mass, by which is equals to proton number + number of neutrons in an atom, according to the Periodic Table of the elements
Can the atomic number be multiplied by two then equal the atomic mass?
Not generally. For light elements this relation is often approximately true, but for heavier elements, the gram atomic mass is more than two times the atomic number, as the ratio of neutrons to protons increases with increasing atomic mass.
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.
Why does the universe contain less hydrogen then it used to?
Some of the hydrogen has been converted into heavier elements by stars.
What contain most of the heavier elements in the Milky Way population stars 1 or 2?
Population I stars
