The periodic table is a chart that organizes all the known elements based on their properties and atomic structure. Each element has a unique symbol, which is usually one or two letters. The first letter is always capitalized, and if there’s a second letter, it’s lowercase.
Looking at the periodic table provided:
- Find the box labeled “Na” — that’s in row 3, column 1 (under Li and above K).
- Next to “Na”, you’ll see the number
11. That’s the atomic number.
- Also next to “Na”, you’ll see the word
Sodium. That’s the full name of the element.
So, Na stands for Sodium, and its atomic number is 11.
Final Answer:
Atomic Number: 11
Element Name: Sodium
