How do you determine the element with a specific number of protons, neutrons, and electrons?

Back

The element is identified by its number of protons, which corresponds to its atomic number. For example, an element with 12 protons, 13 neutrons, and 12 electrons is Magnesium (Mg).

What is the significance of protons in determining an element's identity?

Back

The number of protons in an atom's nucleus defines the element and its position on the periodic table.

Front

What is the role of neutrons in the stability of an atomic nucleus?

Back

Neutrons help to stabilize the nucleus by offsetting the repulsive forces between protons.
