The atomic number is the same as the number of protons.
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.
If two atoms have the same atomic number, it means they have the same number of protons in their nucleus. If they also have the same atomic mass, it means they have an equal number of protons and neutrons. These atoms would be isotopes of the same element.
Yes, in their natural state, the proton and electron number are the same, and thus the same as the atomic number.
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
yes. Isotopes of an element have the same number of protons, thus electorns, thus the same chemical properties. Where isotpes differ is in the number of neutrons. Consider hydrogen, atomic number 1, atomic weight 1, 1 proton, 1 electron vs duterium, atomic number 1 atomic weight 2, 1 proton, 1 electron, 1 neutron. H2O = water D2O = heavy water
No: They have the same atomic number but not the same atomic mass.
The same as its atomic number.
No. Sulfur has an atomic number of 16 and Argon has an atomic number of 18
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.
Atomic number of an element is same as the number of protons. It is same as number of electrons in neutral atom.
In a neutral atom, the number of protons (or the number of electrons) are the same as the atomic number.
the atomic number
If two atoms have the same atomic number, it means they have the same number of protons in their nucleus. If they also have the same atomic mass, it means they have an equal number of protons and neutrons. These atoms would be isotopes of the same element.
No.
Yes, in their natural state, the proton and electron number are the same, and thus the same as the atomic number.
No - atomic number is the number of protons.
The atomic number is the same as the number of protons, ALWAYS.
