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.
Which subatomic particles are used to determine an atoms mass number?
Two particles are considered. they are protons and nrutrons
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 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.
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.
Which two subatomic particles have the greastest mass?
protons and neutrons both are found inside the nucleus
