Isotopes

Deuterium is an isotope of hydrogen. It has one proton and one neutron in its nucleus, compared to regular hydrogen which has only one proton. Deuterium is slightly heavier than regular hydrogen and is often used in laboratory experiments and as a tracer in scientific studies.

Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons. Example: Calcium atom contains 20 protons and 20 neutrons.

But some atoms contain same number of protons but different number of neutrons. For example carbon atoms exist in three forms - all contain 6 protons but some contain 6 neutrons, some 7 neutrons and others with 8 neutrons. These type of atoms are known as isotopes

Definition of isotope: Atoms with same number of protons but different number of neutrons

It shows that the different number of neutrons determines the existence of isotopes.

The most common instrument used to measure isotopes is a mass spectrometer. Mass spectrometry allows scientists to accurately determine the mass and abundance of isotopes in a sample. It works by ionizing the atoms in the sample and separating them based on their mass-to-charge ratio.

An isotonic solution of sodium chloride has a concentration of 9 g/L.

I'm assuming that by "change" you mean alter the quantity thereof. If you want to actually change a proton into a nuetron and eject a positron, that requires a nuclear reaction.

The protons and neutrons are in the nucleus and serve to define the atom, while the electrons orbit the nucleus and ultimately determine the atom's charge. Electrons can be removed or added with a certain amount of energy. This energy is relatively small compared to the massive amounts required to alter the subatomic particles within the nucleus.

They have the same number of protons (and of electrons) and so their chemical properties are the same.

One doesn't generally "calculate" the number of neutrons. The number of neutrons in an atom is always equal to the number of protons, and the number of protons can be found on the Periodic Table of Elements, which can easily be found on the internet or in a science textbook.

Statistically carbon-14 atoms decay at a constant rate.

Yes, unless there are twoisotopescoincidentallyhavingthe equal half lives.

The atomic mass of an isotope is the weighted average of the masses of the naturally occurring isotopes of an element. It is found by multiplying the mass of each isotope by its natural abundance and summing these values. The mass number of an isotope is the total number of protons and neutrons in its nucleus and can be found by rounding the atomic mass to the nearest whole number.

All of them.

yes it does b/c the isotopes have different number of neutrons so therefore isotopes cause a change in mass.

both the atomic number and the atomic mass remain the same.

Yes, but they have varying amounts of neutrons.

The most common isotope of uranium is uranium-238.

The elements that are radioactive in their most common form are radon, technetium, potassium, and uranium. The most obvious use for radon is the automobile industry. Potassium has both medical and agribusiness uses. Uranium is commonly used as a basic fuel for nuclear reactors. Technetium is used in nuclear medicine and industries

An isotope can be produced if a nucleus gains a neutron or if one of the protons in its nucleus decays into a neutron and positron.

well its flippin simple losers

No, potassium-40 is a radioactive isotope of potassium. It undergoes radioactive decay with a half-life of about 1.25 billion years, emitting beta particles in the process.

To be an isotope stable, the number of neutrons should not exceed 1.5 times than protons.

The most abundant isotope of arsenic is arsenic-75.

If the isotope existed, it would have 16 neutrons.

An electron orbital describes in terms of quantum mechanics the position of each electron around the atomic nucleus, and an energy level is associated with each orbital. The orbitals are grouped in shells and sub-shells, and the energy levels are affected by more than one quantum parameter so the picture gets complicated for atoms with many electrons.
