What is the number of subatomic particles in sulfur?
Sulfur has 16 protons and electrons; the number of neutrons is specific for each isotope: Number of neutrons in a sulfur isotope = Mass number - 16
What are the subatomic particles of calcium?
Calcium has 20 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a calcium atom = Mass number - 20
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 element has 28 subatomic particles in the nucleus of one atom?
The only non-radioactive isotope with the specified properties is silicon-28, which constitutes more than 90 % of naturally occuring silicon.
What are the subatomic particles in silicon?
Silicon has 14 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a silicon isotope = Mass number - 14
Which subatomic particles are used to determine an atoms mass number?
Two particles are considered. they are protons and nrutrons
What 2 subatomic particles can you determine form the atomic number?
The number of protons as well as the number of electrons.
What 2 subatomic particles can you determine from the atomic number?
Atomic number is same as the number of protons and number of electrons.
How do you determine sum of subatomic particles?
The mass number is the sum of protons and neutrons in the atomic nucleus.
Why does the number of proton in an atom determine the identity of the element?
Because the protons keep their integrity/identity whilst the electrons act as 'glue' binding all the subatomic particles together.
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.
How do you determine the no of each subatomic particles?
If you use 24He notation then the bottom number in the number of protons and electrons and the top number minus the bottom number is the number of neutrons
What is the number of subatomic particles for oxygen?
24
Has the number of subatomic particles changed?
No, from 80 years.
What is the subatomic particles on which the atomic number is based?
Number of protons in the nucleus is the atomic number.
What does the mass number equal?
The total number of subatomic particles in the nucleus
Is sodium a subatomic particle?
No, sodium is not a subatomic particle. Sodium is a chemical element with the symbol Na and atomic number 11. Subatomic particles are particles smaller than an atom, such as protons, neutrons, and electrons.
