How do you determine sum of subatomic particles?
The mass number is the sum of protons and neutrons in the atomic nucleus.
What is the subatomic particles on which the atomic number is based?
Number of protons in the nucleus is the atomic number.
What is the number of subatomic particles of protons?
The number of protons is equal to the atomic number of a chemical element.
What is ment by atomic number?
Atomic Number is the amount of Protons (positively charged subatomic particles) contained in the nucleus of an atom.
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
What 2 subatomic particles can you determine form the atomic number?
The number of protons as well as the number of electrons.
How do you determine sum of subatomic particles?

What is the subatomic particles on which the atomic number is based?
Number of protons in the nucleus is the atomic number.
What of these subatomic particles are represented by atomic number?
Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
Name the subatomic particles that the number of this particle is always the same as the atomic number?
The proton
The atomic number for an element is the total number of subatomic particles?
False; the atomic number is the total number if protons in the nucleus only.

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.
Which subatomic particles are used to determine an atoms mass number?
Two particles are considered. they are protons and nrutrons
Is Electrons are nearly weightless subatomic particles?
yes. the atomic weight of an atom is determined by how many protons and neutrons it has. determine the number of neutrons by subtracting the atomic number from the atomic mass
Which term is used to describe the way the mass of subatomic particles is described?
Atomic Mass units =]
