Protons and neutrons have similar masses but they do not weigh the same. The mass of a proton is approximately 1.6726 x 10^-27 kilograms, while the mass of a neutron is slightly heavier at approximately 1.6750 x 10^-27 kilograms. This small difference in mass is due to the composition of these particles, with protons having two up quarks and one down quark, and neutrons having two down quarks and one up quark.
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.
Rubidium's atomic number is 37 and atomic number is the same as the protons (37 protons) Protons equal electrons so there is the same number of protons and electrons (37 electrons). The atomic mass of this element is About 85, and protons and neutrons weigh about 1 so you can subtract 37 from 85 to get and 48 neutrons. 37 protons, 37 electrons and 48 neutrons.
2 protons and 2 neutrons. An alpha particle is the same as a helium nucleus.
the you and the stupid! oh wait that is the same thing!
Isotopes of an element have the same number of protons but different numbers of neutrons. For example, carbon-12 and carbon-14 are isotopes of carbon with 6 protons but 6 and 8 neutrons, respectively.
Yes.
These are termed isotopes. They have the same atomic number i.e the same number of protons and therefore the same chemistry but have differemt mass from the most commonly occurring isotope. Neutrons weigh roughly the same as protons.
Periods neither have same protons nor neutrons. They have same shells.
Protons and neutrons have almost the same mass.
the mass number is determined on the number of protons and neutrons in the nucleus of the atom.
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.
Atoms having the same number of protons and neutrons make up the same element.
Carbon Number of Protons/Electrons: 6 Number of Neutrons: 6
It is called an Isotope if you're looking for a quick answer. But to go more in depth you need a bit of background knowledge: An element is determined by the number of protons it has in its nucleus. For example Carbon has 6 protons. Only atoms of carbon will have 6 protons. Atomic mass is measured by the number of protons and neutrons which weigh the same amount. Scientists use a unit called AMU or Atomic Mass Unit which is the equivalent to the weight of 1 proton or 1 neutron. The definition of an isotope is an element with the same number of protons as another, but a different number of neutrons. Here's an example: Carbon-12 and Carbon-14 are two naturally occurring isotopes of Carbon. Both have 6 protons. The numbers stand for the atomic mass of that isotope. Because we know there are 6 protons in the atom, and that protons and neutrons weigh the same amount, we can determine the number of neutrons. 12 (combined neutrons and protons) - 6 (known number of protons) = 6 neutrons The same can be done with the other atom 14-6 is 8 neutrons. Therefore we know that isotopes are the atoms of the same element, with different atomic mass, which is caused by a higher or lower amount of neutrons
no
No, not all atoms weigh the same. The weight of an atom is determined by the combined mass of its protons, neutrons, and electrons. Different elements have different numbers of protons, neutrons, and electrons, leading to variations in atomic weight.
