These are isotopes.
The symbol is Ba. The number of neutrons equal the number of protons.
Atomic mass is the total of the number of protons PLUS the 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
The atomic particle that determines a specific isotope is the number of neutrons in the nucleus of an atom. Isotopes are different forms of an element that have the same number of protons but a different number of neutrons. The number of neutrons affects the mass of the atom and gives rise to different isotopes with varying atomic weights.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
All isotopes of radium have the same number of protons; the number of neutrons is different.
The symbol is Ba. The number of neutrons equal the number of protons.
The number of protons (and electrons in a neutral atom) is identical. The number of neutrons is different for each isotope.
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, it is just the other way around!All isotopes of one particular element have the same number of protons (specific for that element) but are differing in neutron number.Example:Uranium has 92 protons (same as atomic number),butisotope U(235) has 143 neutrons and 92 protons (143+92=235)andisotope U(238) has 146 neutrons and 92 protons (146+92=238).
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.
Promethium has 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
