What else can I help you with?
What two subatomic have about the same mass?
These particles are: proton and neutron.
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
The mass number is the sum of which two subatomic particles?
Neutrons and Protons.
What are the two subatomic particles with a mass?
In the atom, protons and neutrons; the mass of the electron is very small.
Which subatomic particles are used to determine an atoms mass number?
Two particles are considered. they are protons and nrutrons
What two subatomic participles have about the same mass?
These particles are: proton and neutron.
Do nuetrons have higher mass or alpha particles?
alpha particles consist of two protons and two neutrons (helium nucleus) logically one neutron can not have a larger mass than two neutrons and two other subatomic particles of a similar mass
How many subatomic particle would be present in an atom of helium with a mass of 4 amu?
6 subatomic particles. 2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 electrons.
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 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 two subatomic particles are added together to calulate the atomic mass?
Protons, neutrons and electrons.
Which two subatomic particles make up the mass of an element?
Protons and neutrons make up the mass. They are present in nucleus.
