Why are atoms electrically neutral?

Back

Atoms are electrically neutral because they have an equal number of protons and electrons.

Front

What is an isotope?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number and properties, helping to predict their behavior.
