The Atomic Mass is the sum of the number of protons and the number of neutrons found in each atom of that element (electrons do not contribute). They are sometimes seen on periodic tables to have a decimal in the atomic number, this is for elements with more than one common isotope (an isotope of an element is the same number of protons but with a different number of neutrons), in which case an average of the common isotopes can be used.
What else can I help you with?
What are the subatomic particles with no mass called?
Subatomic particles with no mass are called neutrinos. Neutrinos are elementary particles that have extremely small, non-zero masses, but they are considered nearly massless in many calculations due to their very small mass values.
Do subatomic particles have gravity?
Yes, subatomic particles like electrons, protons, and neutrons have mass, which means they do have gravity. Gravity is a fundamental force that affects all objects with mass, regardless of their size.
What two subatomic have about the same mass?
These particles are: proton and neutron.
What does subatomic particles contribute to the value of atomic mass and atomic number?
protons is the same number as the atomic number always and protons plus the average number of neutrons makes up the atomic mass
Which sub atomic particles cause isotopes to appear?
Isotopes are caused by variations in the number of neutrons in an atom's nucleus. Neutrons are subatomic particles that do not carry an electric charge and contribute to an atom's mass. The different number of neutrons in isotopes result in variations in atomic mass.
What are the Subatomic particles with no charges?
Subatomic particles with no charges are neutrons
Does subatomic particles have the smallest mass of any subatomic particle?
The electron has the smallest mass between subatomic particles: 9,10938291(40).10-31 kg.
What two subatomic particles do you add together to get the mass number?
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
What are the subatomic particles with no mass called?
Subatomic particles with no mass are called neutrinos. Neutrinos are elementary particles that have extremely small, non-zero masses, but they are considered nearly massless in many calculations due to their very small mass values.
What are the features of the subatomic particles?
Subatomic particles have mass, dimensions, spin, sometimes have an electrical charge.
Which subatomic particles have mass and re included in the calculation of the atomic mass number?
Protons and neutrons are the subatomic particles that have mass and are included in the calculation of the atomic mass number. Electrons have very low mass compared to protons and neutrons and are usually not included in the atomic mass calculation as they contribute very little to the overall mass of an atom.
What two subatomic particles are added together to determine the mass number?
The two subatomic particles added together to determine the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but both contribute to the mass of an atom.
What statement bout subatomic particles is not true?
"All subatomic particles have the same mass" is not a true statement, as different subatomic particles, such as protons, neutrons, and electrons, have different masses and charges.
What subatomic particles are similar in mass?
neutrons and protons
What subatomic particles has appreciable mass and lacks a charge?
The neutron is the subatomic particle that has appreciable mass and lacks a charge.
Relation between subatomic particles and atomic mass unit?
protons and neutrons are subatomic particles and adding the two amounts together gives you the atomic mass unit
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
