The two notations represent atoms that are isotopes of the same element is 121 Sn and 119 Sn. The Atomic Mass of an element is defined as the weighted average mass of that elements naturally occurring isotopes.
Isotopes are atoms of the same chemical element with different numbers of neutrons in their nuclei. This does not (significantly) change their chemical properties, but it does change the mass of the atoms in the different isotopes.
A pair of isotopes are elements that have a different mass than how they are naturally found in nature (different mass from that shown in the Periodic Table).
Two Atoms that are isotopes have the same atomic number (number of protons), but different numbers of neutrons.
The natural isotopes of neon are 20Ne, 21Ne, 22Ne.
Isotopes of the same chemical element have a different number of neutrons.
The are two isotopes having a different number of neutrons but the same number of protons.
O3 and O4 are two isotope pairs
Same atomic number
Atoms have isotopes: it is true, the isotopes of the same element have different number of neutrons.
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
These atoms are called isotopes.
Atoms have isotopes: it is true, the isotopes of the same element have different number of neutrons.
They are called isotopes,
Elements with isotopic atoms? An isotope is the same form of an element, but with a different number of neutrons. An element with isotopes/"isotopic atoms" is simply an element with isotopes.
An atom or element that have different masses are known as isotopes.
# Elements are not isotopes, atoms are isotopes of an element. # There are no atoms that are not isotopes, so it's not a matter of being "considered" an isotope or not. # It doesn't matter where the neutrons come from, whatever that means. All atoms are isotopes of some element or other.
Isotopes are atoms of the same element that have differing numbers of neutrons. An example would be Cl-35 and Cl-37. Cl-37 has a larger amount of neutrons than Cl-35 has.
Isotopes are atoms of the same element that are only different by the number of neutrons they have
Atoms of the same element that have different masses are called isotopes of the element. The presence of different numbers of neutrons in the nucleus is responsible for the existence of isotopes of an element.
Isotopes are atoms of the same element but with a different number of neutrons.
Isotopes are atoms of an element having different number of neutrons.Ions are atoms with an electrical charge.
Isotopes are atoms of the same element, having the same number of protons but different number of neutrons.
