Although an element’satomsmust all have the same number of protons, they can have different numbers of neutrons and hence differentmasses. When atoms of the same element have different numbers of neutrons, they are calledisotopes. How Elements Came to be Defined Correctly ...

An element is a type of atom, and atoms typically have three components: positive protons, neutral neutrons, and negative electrons. What is the element definition in chemistry? An element is a substance made up of only one type of atom, all with the same number of protons. Gold offers a...
For example, the mass number of a carbon atom with 6 protons and 6 neutrons in its nucleus is 12. Isotopes Although all atoms of an element have the same number of protons in their nuclei, they may not all have the same number of neutrons. Atoms of an element with the same mass ...
In chemistry, how can one tell if an element is able to be paired with another element? Are there any elements in neutron stars, and if so what are they? How do you show the number of protons and neutrons on a Bohr-Rutherford diagram?
