To solve this quiz, we need to list the first 20 elements of the periodic table in order. The quiz asks for two things for each number (1–20):
1. The
atomic symbol (the one or two-letter abbreviation).
2. The
element name.
The periodic table is organized by atomic number, which starts at 1 and goes up. Let’s go step by step from element #1 to #20.

Let me double-check a few tricky ones:
- Sodium is Na (from Latin *natrium*) — correct.
- Potassium is K (from Latin *kalium*) — correct.
- Iron is Fe, but that’s #26, so not in our list — good, we stopped at #20.
- All symbols match standard periodic table notation.
No calculations needed here — it’s memorization/ordering based on atomic number.
Final Answer:
(1) H — Hydrogen
(2) He — Helium
(3) Li — Lithium
(4) Be — Beryllium
(5) B — Boron
(6) C — Carbon
(7) N — Nitrogen
(8) O — Oxygen
(9) F — Fluorine
(10) Ne — Neon
(11) Na — Sodium
(12) Mg — Magnesium
(13) Al — Aluminum
(14) Si — Silicon
(15) P — Phosphorus
(16) S — Sulfur
(17) Cl — Chlorine
(18) Ar — Argon
(19) K — Potassium
(20) Ca — Calcium
