An atom is the smallest unit of an element that keeps its identity. At the center sits a nucleus packed with protons carrying a positive charge and neutrons carrying none, which together hold nearly all the mass. Electrons move around it in regions called an orbital, grouped into a shell. The outermost is the valence shell, and it decides how the atom bonds. Atoms of one element with different neutron counts are an isotope. This word puzzle gathers eleven terms.
Frequently asked questions
What is a valence shell in this atoms word search?
The VALENCE shell is the outermost region holding electrons. How full it is determines how readily the atom forms bonds.
What makes an isotope different?
An ISOTOPE has the same number of protons as its element but a different number of NEUTRON particles, so its MASS differs.
Does the PDF include an answer key?
Yes, the PDF has the puzzle on page one and the full answer key on page two.
