Isotopes can either be stable or unstable. Unstable isotopes have an uneven number of protons and neutrons. Stable isotopes have the same number of protons and neutrons. The number of usual protons in an element is found in the Atomic Mass, but I won't go there.
(hope this helps, this is what we're learning about in our science class)
The number of neutrons is different.
The number of neutrons is different.
they are different isotopes of copper 1 has 2 more neutrons than the other
They differ from each other in the number of neutrons, and therefore also the mass. They will also have different stabilities (for example, some of them may be radioactive), but this is complicated.
Isotopes are variant forms of an atom that differ in the number of neutrons. Each isotope of an element has the same number of protons but different numbers of neutrons. These variations in neutrons give each isotope a slightly different atomic mass.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
The number of neutrons is different.
They have the same formulas but different organic structures.
The number of neutrons is different.
No they don't have. Isotopes of an element differ in mass from from each other and this is due to the different no. of electrons in their nucleus.
they are different isotopes of copper 1 has 2 more neutrons than the other
Isotopes differ each other from the number of neutrons which is a chemically inert subatomic particle.
Bohr theory was introduced using hydrogen atom, it's not applicable to each and every atom, even for the other isotopes of hydrogen.
They differ from each other in the number of neutrons, and therefore also the mass. They will also have different stabilities (for example, some of them may be radioactive), but this is complicated.
Yes - by the basic definition of an element; excepting only isotopes of an element, which differ slightly from each other in atomic structure, but not enough to affect the element's outwards physical and chemical properties.
The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.
Isotopes are variant forms of an atom that differ in the number of neutrons. Each isotope of an element has the same number of protons but different numbers of neutrons. These variations in neutrons give each isotope a slightly different atomic mass.
