What element has 4 neutrons?

Understand the Problem

The question is asking for the identification of a chemical element based on the number of neutrons it has. To determine which element has 4 neutrons, we would need to consider isotopes and their atomic number (the number of protons). If we know the atomic number, we can then find the corresponding element having 4 neutrons.

More Information

Lithium, the third element on the periodic table, has three protons and commonly has four neutrons, making its most common isotope, lithium-7, stable.

Tips

A common mistake is confusing the number of neutrons with the number of protons or electrons in an element, which does not necessarily match.
