Elements (Periodic Table) — Easy Word Search
| Grid size | 12x10 |
|---|---|
| Words to find | 10 |
| Font size | 16 pt |
| Paper | A4 & US Letter |
| Answer key | Included |
| Puzzle ID | EPT-E-037 · v2026.3 |
Ten chemical elements every solver already knows by their common name, chosen for recognition over completeness.
The shortest words ("tin" and "gold") help new solvers gain confidence quickly, while longer entries such as "carbon" and "oxygen" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 10 words (gold, iron, lead, tin, zinc, neon, copper, silver, carbon, oxygen) across a 12x10 grid, using 11 of its 18 unique letters at least twice.
Why we chose this word list
Every word here is a genuine element from the periodic table, not a compound or alloy — accurate chemistry from the very first level.
Metals (gold, iron, copper) and non-metals (carbon, oxygen, neon) are both represented, avoiding a metals-only first impression of the periodic table.
Vocabulary analysis
Measured directly from this puzzle's own grid — not a generic estimate.
Why this level is easy
- Only horizontal and vertical words — no diagonals
- No reversed words
- Short, everyday vocabulary
- No uncommon spellings
- Minimal overlaps between words
This puzzle satisfies every requirement of our easy level, as defined in our published methodology and applied consistently across every easy puzzle on this site.
Elements (Periodic Table) — Medium Word Search
| Grid size | 15x15 |
|---|---|
| Words to find | 15 |
| Font size | 13 pt |

Fifteen elements that appear constantly in chemistry class and everyday life, from the air we breathe to the bones in our body.
The shortest words ("argon" and "helium") help new solvers gain confidence quickly, while longer entries such as "magnesium" and "phosphorus" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 15 words (hydrogen, nitrogen, helium, sodium, potassium, calcium, chlorine, sulfur, phosphorus, magnesium, aluminum, silicon, fluorine, argon, titanium) across a 15x15 grid, using 17 of its 18 unique letters at least twice.
Why we chose this word list
"Calcium" and "phosphorus" are included together deliberately, since both are essential to bone health — chemistry with a direct link to biology.
"Argon" and "helium" represent the noble gases at this level, setting up the "noble gas" classification explored fully at the Hard level.
Vocabulary analysis
Measured directly from this puzzle's own grid — not a generic estimate.
Why this level is medium
- Horizontal, vertical and diagonal words
- No reversed words
- Mixed word lengths, some less common vocabulary
- Moderate overlaps between words
This puzzle satisfies every requirement of our medium level, as defined in our published methodology and applied consistently across every medium puzzle on this site.
Elements (Periodic Table) — Hard Word Search
| Grid size | 20x20 |

Twenty terms from real atomic structure and periodic table organization — valence, electronegativity, isotopes — the vocabulary a chemistry course actually teaches.
The shortest words ("shell" and "noble") help new solvers gain confidence quickly, while longer entries such as "radioactive" and "electronegativity" encourage them to scan the whole grid instead of stopping after the first few finds. In total, this puzzle hides 20 words (isotope, valence, electron, proton, neutron, nucleus, shell, periodic, atomic, electronegativity, ionization, compound, molecule, reactivity, alkali, halogen, noble, metalloid, radioactive, synthetic) across a 20x20 grid, using 18 of its 21 unique letters at least twice.
Why we chose this word list
"Alkali", "halogen", "noble" and "metalloid" are the actual named groups elements are organized into on the periodic table — precise classification, not casual description.
"Isotope" is a genuinely important concept (atoms of the same element with different neutron counts) central to both chemistry and nuclear physics.

Why this level is hard
- All eight directions, including reversed words
- Longer, denser word list
- Similar-looking decoy letter sequences in the filler
- Frequent overlaps between words
This puzzle satisfies every requirement of our hard level, as defined in our published methodology and applied consistently across every hard puzzle on this site.
