What is the neutrons mass the same as?
neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.
What is an element’s mass equal to?
Forms of the same atom that differ only in their number of neutrons are called isotopes. Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons.

Why does hydrogen have a mass of 1?
The atomic number is equal to the number of protons in an atom’s nucleus. Hydrogen’s atomic number is 1 because all hydrogen atoms contain exactly one proton. Related Pages: What is an element?
Why isn’t the atomic mass of hydrogen a whole number?
Atomic mass is never an integer number for several reasons: The atomic mass reported on a periodic table is the weighted average of all the naturally occuring isotopes. Because energy is required to hold the nucleus together in all atoms except Hydrogen-1, a small loss of mass (the m in the equation) occurs.
What is atomic mass and how is it determined?
The atomic mass of the atom is the mass of the protons plus the mass of the neutrons, 6 + 7, or 13. The atomic mass of an element is a weighted average of all the element’s isotopes based on their natural abundance. It is simple to calculate the atomic mass of an element with these steps.
What does the atomic mass tell us?
Atomic mass of an element tells us the number of times an atom of the element is heavier than of the mass of an atom of carbon-12. A unit suitable for the mass of atoms and the mass of subatomic particles is the atomic mass unit (u).
What is 1 amu equal to?
You can view more details on each measurement unit: amu or kilogram. The SI base unit for mass is the kilogram. 1 amu is equal to 1.6603145E-27 kilogram.
What is the average atomic mass of an atom?
An atom has an average atomic mass of about 63.5 amu. 1 amu is equal to 1 gram per mole.
