Grade 10 atomic structure identifies an element by proton number (atomic number) and isotopes by neutron count. Students connect electron configuration and valence electrons to periodic trends such as radius and ionization energy. Spectra and quantized energy levels explain why atoms emit specific colors.

What you practice

These are the Grade 10 Atomic Structure & Periodic Table skills this quiz is built around.

Use atomic number and mass number to find protons, neutrons, and electrons in a neutral atom or ion.
Relate valence electrons and group number to likely ion charge for main-group elements.
Describe a periodic trend such as atomic radius or ionization energy across a period.

A useful tip

Atomic number is protons, which define the element. Mass number is protons plus neutrons. Changing neutrons makes an isotope; changing protons makes a different element.
