Now we're consult with your professor because normally they want you to memorize a set number of elements with their symbols. So take this to heart when you're learning about each of these elements. ![]() And it's organized in terms of increasing atomic number so that groups that have similar chemical properties um well, element that fall in certain groups have similar chemical properties. Mendeleev had a big part in playing when organizing the periodic table. So just remember, the periodic table can be credited from Levasseur Mendeleev organ organizational wise. But these 11th special 11 ones, they're symbol comes from the old Latin name that has been replaced over time. For the most part, we can see that the name comes from the first letter or first few letters of the name. ![]() And then finally, antimony, which is S b the rest of the elements. So those elements include sodium, which is n a potassium, which is K iron, which is F e tungsten, which is w copper, which is see you silver, which is a g gold, which is a you mercury, which is H g tin, which is S n um lead, which is PB. That's because the symbol is based on the old Latin name that has been replaced over time with this new modern one. Now, the Latin names are not as important, but it's it's good to know that certain names and certain symbols don't really match up to Well. Symbol is ally, but there are 11 elements on the periodic table, which aren't based on the first level letters of their name, but actually based on their Latin names. Lithium starts with Ally, so it's elements. Hydrogen starts with an H, so it's element. Now most elements it's based on the first letters of their names. Now the elements symbol itself is just the abbreviated form of an element. So although there were about 23 elements at the time when they started organizing this by organizing in the way that they did, they could predict that other elements to be found over time. He could predict that in this slot and element would be found eventually. This was the genius of mentally by organizing in terms off, it's increasing atomic number. When they're in the same group, they're gonna share similar chemical properties. By organizing the periodic table in terms of increasing atomic number, elements are allowed toe fall within certain columns or groups. So here hydrogen has the lowest atomic number, and as we start moving, we'll see that the atomic number is increasing. ![]() Remember, your atomic number uses the variables E, and it basically tells us the number of protons for any particular element. Now, how does this connect to the periodic table? Well, the periodic table here has all of these elements with their symbols, and we're going to see the periodic table itself could be seen as a great of elemental symbols that is organized in terms of increasing atomic number. He used the term periodic law to justify the way he organized the elements. And in 18 69 it was Mendeleev who organized them by by their recurring or periodic chemical properties. At the end of the 18th century, it was Antoine Lucas or who compiled a list of 23 elements and their symbols known at the time. Now, before we talk about the periodic table, the elements and their symbols, let's go over a little bit of history.
