The periodic table isn’t just something to memorise for exams—it’s everywhere. From the air you breathe to the phone in your hand, this colourful grid of elements is shaping your daily life more than you realise. Let’s break it down and discover just how essential it is.
What Is the Periodic Table, Again?
The periodic table is a chart that organises all known chemical elements by their atomic structure and properties. Each element has:
- A symbol (like H for hydrogen or O for oxygen)
- An atomic number (the number of protons)
Chemists rely on it to understand reactions—but so do engineers, doctors, and even chefs!
1. It’s In the Air You Breathe
Each breath you take includes:
- Oxygen (O₂) – for cell energy
- Nitrogen (N₂) – helps regulate breathing pressure
- Carbon dioxide (CO₂) – produced when you exhale
All of these are elements listed on the periodic table—essential for life.
2. In Every Drop of Water
Water = H₂O = hydrogen + oxygen.
Even your sweat, tears, and urine contain elements like sodium (Na), potassium (K), and chlorine (Cl)—all crucial for bodily function.
3. On Your Dinner Plate
Your food is packed with elements:
- Iron (Fe) – boosts oxygen in your blood
- Calcium (Ca) – for bones and teeth
- Sodium (Na) + Chlorine (Cl) = table salt (NaCl)
Yup, chemistry helps your food taste good and keep you healthy.
4. In Your Gadgets
Your phone contains over 30 elements! Including:
- Lithium (Li) – battery power
- Silicon (Si) – screens and chips
- Gold (Au), Copper (Cu), Tantalum (Ta) – circuits and signal
Tech + Chemistry = 🤝 forever.
5. In Your Bathroom
Chemistry is in your hygiene routine too:
- Fluorine (F) – strengthens teeth
- Zinc (Zn) – tackles dandruff
- Magnesium (Mg), Calcium (Ca) – affect soap lather
Even perfume is just a fancy chemical mix!
6. Inside Your Body
You are the periodic table:
- 96% of you = C, H, O, N
- Iron (Fe) – red blood cells
- Iodine (I) – healthy thyroid
You’re literally walking chemistry.
7. In Fuel & Energy
From petrol to clean energy:
- Carbon (C) – fuels combustion
- Hydrogen (H) – clean fuel alternative
- Uranium (U) – powers nuclear plants
Yup, your car rides and cooking gas? That’s chemistry again.
Chemistry Is Everywhere
The periodic table isn’t just a boring chart—it’s a map of life. So next time you see it in your textbook, remember: you’re not just memorising symbols. You’re exploring what makes the world work.
