Definition: A chemical element, atomic number 22; it is a strong, corrosion-resistant transition metal, used to make light alloys for aircraft etc.

Alright class, settle down, let’s take a look! Today we’re tackling the word “titanium,” and I think you'll find it quite intriguing. The dictionary has given us a good starting point, but let’s break it down in a way that makes sense. “Titanium” is a chemical element , that’s really important to know! Think of it like building blocks – tiny pieces that make up everything around us. Its atomic number is 22 - that's just a special code, a number that tells scientists exactly how many protons are in its center. Now, let's talk about what makes it so special: It’s a “strong, corrosion-resistant transition metal.” Let’s unpack that! Strong: This means it can hold up against a lot of pressure, like a really sturdy bridge beam. Corrosion-resistant: That’s the key part! Corrosion is when things rust or break down because they react with air and water. Titanium doesn't do that – it stays shiny and strong for a very long time. Transition Metal: This just means it changes its properties, like shifting from one state to another - think of it like a chameleon! And finally, the dictionary tells us it’s used in “light alloys for aircraft etc.” That means they mix titanium with other metals to make things lighter but still incredibly strong. Think airplanes – that's where titanium shines (pun intended!). So, in short: Titanium is a remarkably tough and long-lasting metal. It doesn’t rust, it's strong, and it’s used in some pretty amazing places! Do you have any questions about this remarkable element? Let's discuss!
