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.

Why atomic mass is different from the mass numbers?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
What is the atomic mass of a atom?
The sum of the numbers of protons and neutrons.
What is the same about protons and electrons?
No, they are completely different. A proton is much larger than and electron and carries a positive charge. Protons can be divided into smaller particles called quarks. An electron is tiny compared to a proton and carries a negative charge. Electrons are fundamental particles, meaning they cannot be divided into smaller particles.
Why actual atomic mass is greater than mass number?
Mass number = number of protons + number of neutrons in an atom
What has the smaller mass protons electrons or nutrons?
Electrons have a smaller mass than both protons and neutrons. Both protons and neutrons are over 1800 times as massive as electrons.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater

What is found with the neutrons and have a greater mass than electrons?
protons
Do protons electons and neutrons differ in mass?
As I remember neutrons and protons weight something similar, electrons have a far smaller mass which is negligable in comparison to the weight of protons.
Larger a nucleus is the greater its?
the larger the nucleus is, the greater the cell's mass
The number of an element determines its?
it depends which number you are referring to. in the periodic table, the numbers referr to number of protons and then relative atomic mass. the larger number is relative atomic mass and the smaller number is the number of protons for example, chlorine, has a relative atomic mass of 35.5 and a proton number of 17
How do you get atomic mass?
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
What is the sum of the numbers of protons in the neutrons in the nucleus?
The mass number.
What is the atomic mass of a atom?
The sum of the numbers of protons and neutrons.
