it's atomic mass- e.g weight in protons and neutrons, electrons weigh virtually nothing
The number of nucleons (protons and neutrons) provides the number of the isotope. For example, 3H, called hydrogen-3 or tritium, has very nearly the same mass, and exactly the same isotope number, as 3He, or helium-3.
What else can I help you with?
Do neutrons determine the conductivity of the atom?
Neutrons do not directly affect the conductivity of an atom. Conductivity is primarily determined by the number and mobility of electrons in an atom. Neutrons only contribute to the mass of the atom and play a role in stabilizing the atomic nucleus.
How many neutrons are in one atom?
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
Define the term mass number?
Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered. I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.
How many neutrons are in an atom of 18O?
An atom of 18O has 10 neutrons. This is calculated by subtracting the atomic number (which is 8 in this case) from the atomic mass number (18).
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
Is determined by the number of protons and neutrons in a atom?
Atomic mass.
What determines the isotopes of an atom?
Different isotopes of an atom are determined by the number of neutrons it contains.
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
How many neutrons does an atom of 21Ne have?
An atom of 21Ne has 11 neutrons. This is determined by subtracting the atomic number (which is 10 for neon) from the atomic mass number (which is 21 in this case).
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
What contributes to an atom's atomic number and to its mass number?
An atom's atomic number is determined by the number of protons in its nucleus, which are positively charged. The mass number is the sum of the protons and neutrons in the nucleus, as neutrons contribute to the atom's mass but not its charge.
Can an atom be determined by knowing the number of neutrons?
No, only by the atomic number, also known as the number of protons.
If the atom has 14 protons and 12 neutrons what the atomic number?
The atomic number is the number of protons in an atom's nucleus, which in this case is 14. This is because the atomic number is determined by the number of protons in an atom, not the number of neutrons.
How many neutrons are present in atom of iron 54?
An atom of iron with a mass number of 54 contains 30 neutrons. This can be determined by subtracting the atomic number (26) from the mass number (54), which gives the number of neutrons in the nucleus.
What is counted in an atom to determine mass number?
The mass number of an atom is determined by counting the total number of protons and neutrons in its nucleus. Electrons, which are much lighter than protons and neutrons, are not included in the mass number calculation.
How can an atoms mass number be determined?
it is the sum of the protons and neutrons present in the nucleus of the atom.
