These are isotopes.
Atomic mass is the total of the number of protons PLUS the number of neutrons.
An isotope is a particle that has an unequal number of protons and neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons. These variations in the number of neutrons result in different atomic masses for isotopes of the same element.
Uncombined atoms have the same number of neutrons as protons only if they are isotopes of the element, which means the atoms have the same number of protons but different numbers of neutrons. Otherwise, atoms with the same number of protons and neutrons would be considered as different elements.
Oxygen has 8 electrons and protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - Number of protons
Promethium has 61 protons and electrons; For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
The pair below that describes isotopes of the same element is B, an atom with 6 protons and 6 neutrons-an atom with 6 protons. It is not A, an atom with 6 protons and 8 neutrons- an atom with 8 protons and 6 neutrons. Isotopes of the same element have the same number of protons and electrons, which is the atomic number of the element.
All isotopes of radium have the same number of protons; the number of neutrons is different.
The number of neutrons in an atom is determined by subtracting the atomic number (number of protons) from the mass number. Neutrons help stabilize the nucleus of an atom by balancing out the positive charge of the protons. Different isotopes of an element have different numbers of neutrons.
Protons are positively charged Neutrons are negatively charged The number of protons is the atomic number Protons+Neutrons=Atomic weight
Uranium isotopes have 92 protons and electrons; the number of neutrons is different for each isotope.Number of neutrons = Mass number - Number of protons
Atoms which have different number of protons and neutrons but have the same molecular weight are called Isobars.
Each chemical element has a different number of protons; the number of neutrons can be similar.
Atomic mass is the total of the number of protons PLUS the number of neutrons.
NO they have same number of protons. But neutrons are different.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
Same number of protons, different number of neutrons
Promethium has 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
