The 118 elements are the different types of atoms currently known to exist, each distinguished by its unique number of protons. They are organized in the periodic table, with each element having a specific symbol and atomic number.
These elements constitute all known matter in the universe. Here's a further explanation:
-
Elements are fundamental building blocks: Elements are pure substances that cannot be broken down into simpler substances by chemical means.
-
Atomic Number: Each element is identified by its atomic number, which represents the number of protons in the nucleus of its atoms.
-
Periodic Table Organization: The elements are arranged in the periodic table based on their atomic number and recurring chemical properties.
-
Examples of Elements:
- Hydrogen - H (Atomic number 1)
- Helium - He (Atomic number 2)
- Lithium - Li (Atomic number 3)
- Beryllium - Be (Atomic number 4)
- Boron - B (Atomic number 5)
- Carbon - C (Atomic number 6)
- Nitrogen - N (Atomic number 7)
- Oxygen - O (Atomic number 8)
The elements and their properties dictate the behavior of all matter, and understanding them is fundamental to chemistry, physics, and many other scientific disciplines.
