no.

In atoms, only the Protons count as atomic number
The neutrons and the protons together is as the Atomic Mass
Yes. The only difference is the atomic mass. They are the same element, therefore the same Atomic Number (represented as 'Z') The reason for the different amount of nuetrons is because of isotopes or radiation of that specific element.
The atomic number is the same as the number of protons, ALWAYS.
They are called isotopes.
Different isotopes of the same element have different numbers of neutrons but the same number of protons. The sum of the protons and neutrons is called the mass number. If you know the mass number and the number of protons (which is the atomic number), then you simply subtract the protons (or atomic number) from the mass number and the result is the number of neutrons. Example: Carbon-14 has a mass number of 14. Carbon's atomic number (and number of protons) is 6. So, 14 - 6 = 8 neutrons.
Isotopes of uncharged elements have the same number of protons (which determines the element), but different numbers of neutrons. For example, carbon-12 and carbon-14 are isotopes of carbon with different numbers of neutrons but the same number of protons.
The number of protons for any element is the atomic number. The number of electrons is equal to the number of electrons. To find the number of nuetrons you must subtract the atomic number from the mass number mass number-atomic number= number of nuetrons protons=electron the number of protons in the element aluminum is 13. The number of electrons is 13.
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+ chargeI hope that answers your question
The number of protons in the nucleus of an atom tell you which element you are dealing with. It is the number of protons in an atomic nucleus that determines the elemental identity. Only that. The atomic number of an element is the number of protons you will find in the nucleus of every atom of that element, regardless of the number of neutrons or electrons involved.
Yes. The number of protons is what determines atomic number.
No, the atomic number is the number of protons that an atom contains. Atomic weight is the number of protons and neutrons.
The atomic number is the same as the number of protons in an element. It is sometimes also the same as the number of electrons depending on the charge of the element.
The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons.
