In a Periodic Table, yes. For example, sodium's atomic number is 11, that means it has 11 protons and electrons because in the periodic table the elements have no charge. However, the sodium ion (Na+) has 1 positive charge, which means that metal lost 1 electron. Therefore, the number of protons never change because otherwise it would be another element, but the number of electrons will decrease by 1.
Na = 11 protons and electrons.
Na+ = 11 protons and 10 electrons = 1+ charge

∙ 15y agoNot always- If the element in question is not an isotope, than the number of nuetrons and the atomic number will be the same. If the element is an isotope (the molecule has extra nuetrons in the nucleus) then they will not be the same. The number of protons will ALWAYS be the same as the atomic number, while nuetrons can change based on the isotope.

∙ 13y agoNo - neutrons do NOT determine the atomic number of an atom.
the number of protons in the nucleus of an atom is equal to the atomic number
this is because you can have many different isotopes of the same elements.
for example - you can have Oxygen with mass number - 16 atomic number = 16
and have Oxygen with mass number - 17 atomic number 16 still.
In this example, 1 extra neutron has been added, making it go +1 in mass, but the atomic number is still the same as no protons have been added/taken away.
isotopes have the same number of protons and electrons as the original element but have a different number of neutrons. this makes the mass change-depending on the number of neutrons but the ATOMIC number stays the same.
so, basically - if the number of protons change, the atomic number changes
- if the number of neutrons change, the mass of the atom differs
but NOT the atomic number.

∙ 14y agoNo, in a neutral atom the no of electrons is equal to atomic no but not the neutrons.
Wiki User
∙ 12y agoThe atomic number is always equal to the number of protons.
Only for (neutral) atoms this number is also equal the the electron number, for ions it is differing from that!
Wiki User
∙ 12y agoNo, an isotope is a variant of an element that has a different number of neutrons. Atomic number is the number of protons in an element.
Wiki User
∙ 12y agoThe atomic number is identical to the number of electrons in neutral atoms.

How can you calculate the number of neutrons N in an atom?
equal to number of protons
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
What atoms with same atomic number but different atomic masses?
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
How many protons and neutrons are present in boron?
The number of protons in an element is its atomic number. Boron's atomic number is 5 - ergo, there are 5 protons. The number of neutrons in an element is the difference between the atomic mass and the atomic number of an element. boron's atomic mass is 11. Therefore, 11 - 5 = 6. There are 6 neutrons in boron. In conclusion, there are 6 neutrons and 5 protons in boron.
The number of neutrons are equal to to the?
Typically to find the number of neutrons, you first round the atomic mass to the nearest whole number. After that to you subtract the number of protons (which is the same as the atomic number) from the newly rounded atomic mass and the resulting number is the number of neutrons. lets use Carbon for example: Atomic mass: 12.01 Atomic mass rounded: 12.00 Number of Protons (same as atomic number): 6 (Rounded atomic mass - number of protons)=6 So Carbon has 6 neutrons. Hope that is easy enough to understand.
How do protons and neutrons relate to an elements atomic number?
The atomic number is the same as the number of protons. It is unrelated to the number of neutrons.
Are neutrons in an atom and the atomic number the same?
No - atomic number is the number of protons.
Is atomic number the number of protons and neutrons?
No, the atomic number is the same number of protons and electrons. To find the neutrons, you subtract the atomic weight by the atomic number. Make sure to round the atomic weight as well.
Isotopes are atoms of the same element that have?
Isotopes are atoms that have the same number of protons and electrons. They have the same atomic number on the periodic table but they have a different number of neutrons and so they have different mass. Isotopes of the same element can have different chemical properties.
What element has the Same atomic number but different number of neutrons?
Almost all the elements have different isotopes having same atomic no but different mass no or neutrons.
Are neutrons the same as mass numbers?
No. The number of neutrons is represented by the element's atomic number, not the mass number.
Is the atomic weight the same as the atomic number?
No, the atomic number is the number of protons that an atom contains. Atomic weight is the number of protons and neutrons.
Do sulfur-36 and argon-36 have the same atomic number?
No, they have the same atomic mass, which is the number of protons plus the number of neutrons. No two elements have the same atomic number.
Is atomic mass and atomic number the same thing?
No, Atomic number is the number of protons in an atom. Atomic mass is the number of protons plus the number of neutrons.
How is mass number and atomic number the same?
They are not. Atomic number is the total number of protons in an atom. Mass number is the total number of protons and neutrons. The only isitope in which they are the same is Hydrogen-1 with 1 proton and no neutrons.
How many neutrons are in one atom in fluorine?
subtract the atomic number by the Atomic Mass, and that is the answer. if its a neutral atom, there are probably the same number neutrons as protons.
If an atom has an atomic namber of 20 and a mass namber of 53 how many protons and neutrons does that atom have?
uh, for one thing mass and atomic nUmbers. and the other: it has 20 protons and 33 neutrons. The atom would have 20 protons and 33 neutrons. The number of protons is always the same as the atomic number. To find the number of neutrons, you simply subtract the atomic number from the atomic mass. Atomic mass - Atomic number = number of neutrons (53 - 20 = 33) If you add the number of protons and the number of neutrons together, you should get the atomic mass.
