What is an isotope how does it differ from the standard of an element?

Answer 1

First: isotopes are not 'special' forms of elements, they are just (normal) elements.

Isotopes of one element are only different nuclear configurations of that same element, which varies only in the number of neutrons present: thus only their mass is different.

Since mass is not a chemical property, isotopes are chemically speaking identical and that's why they are on the 'same spot' in the (chemical) Periodic Table: 'iso' = same, 'topos' = place.

Answer 2

isotope refers to the elements having the same atomic no. but different mass no. and the occurrence of isotopes are less as compared to standard form of elements

because the common standard ones have different atomic no. as well as diff mass no.similarly isobars have same mass no. and diff atomic no.............interesting isn't it?

Answer 3

Each atom has a number pf protons and a number of neutrons in its nucleus.

Each atom of an element has the same number of protons in its nucleus.

Atoms of different isotopes (i.e. same protons) have the same number of protons but different numbers of neutrons in their nuclei.

Atoms of different isotones (i.e. same neutrons) have different numbers of protons but the same number of neutrons in their nuclei.

Answer 4

An isotope is a variant of an element that has the same number of protons but a different number of neutrons in its nucleus. This results in isotopes having different atomic weights. The standard element is typically the most common isotope of that element found in nature, but there can be multiple isotopes of an element.

Answer 5

an isotope of an element has different number of neutrons than standard element

Answer 6

The number of protons and electrons is the same.

Answer 7

Isotopes have a different number of neutrons.
