🔹 Basic Information Zirconium is a strong, corrosion-resistant metal mostly used in nuclear reactors, ceramics, and jewelry. It’s found in nature as part of minerals like zircon, and it’s prized for its heat resistance and shiny appearance. 🔸 Chemical Properties Zirconium forms stable compounds and resists corrosion, even from acids and seawater. It is a…

🔹 Basic Information Calcium is a soft gray metal that plays a vital role in the human body and the Earth’s crust. Though it’s a metal, it’s mostly found in compound form in nature. 🔸 Chemical Properties Calcium is highly reactive with water and oxygen, which is why it’s not found in pure form in…

🔹 Basic Information Potassium is a highly reactive metal that is essential for life but never found free in nature. It’s soft enough to cut with a knife and reacts instantly with water. 🔸 Chemical Properties Potassium is extremely reactive, especially with water, producing heat, hydrogen gas, and a purple flame. This is why it’s…

🔹 Basic Information Chlorine is a pale green, poisonous gas with a strong, sharp smell. It belongs to the halogen family, a group of elements known for being very reactive and often used in disinfectants, salts, and chemical reactions. 🔸 Chemical Properties Chlorine is one electron short of a full outer shell, which makes it…

🔹 Basic Information Argon is a colorless, odorless, and tasteless gas. It’s one of the noble gases, meaning it doesn’t react easily with other elements. It makes up about 0.93% of the air we breathe — the third most abundant gas in the Earth’s atmosphere after nitrogen and oxygen. 🔸 Chemical Properties Argon’s outer shell…

🔹 Basic Information Sulphur is a non-metal element with a distinctive yellow color and strong smell (like rotten eggs, in some compounds). It’s found in volcanoes, hot springs, and minerals, and plays important roles in the environment and biology. 🔸 Chemical Properties Sulphur has six electrons in its outer shell, making it reactive, especially with…

🔹 Basic Information Phosphorus is a non-metallic element that comes in several forms, mainly white, red, and black phosphorus. It’s best known for being highly reactive, especially white phosphorus, which can catch fire in air! 🔥 🔸 Chemical Properties Phosphorus atoms have five outer electrons, which makes them ready to form strong chemical bonds, especially…

🔹 Basic Information Silicon is a metalloid, meaning it has properties of both metals and non-metals. It’s the second most abundant element in the Earth’s crust, found mainly in sand, rocks, and soil. 🔸 Chemical Properties Silicon isn’t very reactive under normal conditions but forms strong bonds in silicates and silicones. It’s the backbone of…
