Question

How do isotopes of an element differ? How are they similar?

Answer 1

Isotopes are variations of a specific compound component that contrast in neutron number, and subsequently in nucleon number. All isotopes of a given component have a similar number of protons however various quantities of neutrons in every particle.

Complete answer:
Radioactivity springs up regularly in the news. For example, you may have found out about it in conversations of thermal power, the Fukushima reactor misfortune, or the improvement of atomic weapons. It additionally appears in mainstream society: numerous superheroes' source stories include radiation openness, for example—or, on account of Spider-Man, a nibble from a radioactive creepy crawly.
Isotopes are iotas of a similar component (same nuclear number, the i.e. same number of protons in the core) yet unique nuclear masses (distinctive mass numbers) because of various quantities of neutrons in the core. For instance, we may get an isotope of chlorine with 17 protons and 18 neutrons, subsequently nuclear mass 35.
And afterward an alternate chlorine iota with 17 protons and 19 neutrons, subsequently a nuclear mass of 36. The estimation of nuclear mass (molar mass) given on the intermittent table is the normal mass once all conceivable happening isotopes of the specific component are mulled over and are the normal mass of 1 mole of that component. On account of chlorine, 35.5, which implies that on normal the mass of 1 mole of chlorine iotas would weigh 35g.

Note: An isotope is one of at least two types of a similar synthetic component. Various isotopes of a component have a similar number of protons in the core, giving them a similar nuclear number, yet an alternate number of neutrons giving each basic isotope an alternate nuclear weight.
