Elements in the Periodic Table

2024-04-23 03:34:08
Did you know that the element with the highest atomic number in the periodic table is oganesson? It was discovered in 2002 and is a highly unstable element that only exists for a fraction of a second before decaying. Another interesting fact is that helium is the only element that was first discovered in space before being found on Earth. It was discovered in 1868 during a solar eclipse. Out of the 118 known elements, 90 of them occur naturally on Earth. The remaining elements have only been created in labs through experiments. The most abundant element in the Earth's crust is oxygen, making up about 46% of the Earth's mass. Meanwhile, hydrogen is the most abundant element in the universe, making up about 75% of its elemental mass. The transition metals are a group of elements in the periodic table that share similar properties, such as being good conductors of electricity and having high melting points. The most well-known transition metal is iron, which is essential for the function of hemoglobin in our blood, responsible for carrying oxygen throughout our bodies. Remember, the periodic table is organized by increasing atomic number, which is the number of protons in an atom's nucleus. It is a fundamental tool in chemistry for understanding the properties and behavior of elements.
