Isotopes are atoms of the same element which differ in the number of neutrons they contain. For example, helium-3 (3He), with two protons and one neutron in each nucleus, and helium-4 (4He), with two protons and two neutrons, are two different isotopes of helium. Nearly all elements found in nature are mixtures of several different isotopes. Although the chemical properties of isotopes of the same element are the same, the physical properties differ. The natural proportions of the isotopes are expressed in the form of an abundance ratio.
Isotopes of the same element contain the same number of protons and electrons but a different number of neutrons.
Two different isotopes of the same atoms have the same number of protons and electrons; the number of neutrons is different.
one proton. :)
Most elements contain a mixture of two or more isotopes.

Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.
They are isotopes of each other.
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.
Most elements contain a mixture of two or more isotopes.
No, only elements are made of one type of atoms.
No, they contain different number of electrons. Isotopes differ in their number of neutrons.
they are known as isotopes. Dont ask people to do your homework
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.

Atoms of the same element that differ in the number of neutrons they contain are known as isotopes.
In one molecule of NaCl there are two ions, Na+ and Cl-.
Only two type of atoms (excepting the situation with isotopes)
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
Two atoms that have the same number of protons are called isotopes.
