- Hydrogen (Wikipedia)
Hydrogen is a chemical element; it has the symbol H and atomic number 1. It is the lightest and most abundant chemical element in the universe, constituting about 75% of all normal matter. Under standard conditions, hydrogen is a gas of diatomic molecules with the formula H2, called dihydrogen, or sometimes hydrogen gas, molecular hydrogen, or simply hydrogen. Dihydrogen is colorless, odorless, non-toxic, and highly combustible. Stars, including the Sun, mainly consist of hydrogen in a plasma state, while on Earth, hydrogen is found as the gas H2 (dihydrogen) and in molecules, such as in water and organic compounds. The most common isotope of hydrogen, 1H, consists of one proton, one electron, and no neutrons.
- Freedom Caucus (Wikipedia)
The Freedom Caucus, also known as the House Freedom Caucus, is a congressional caucus consisting of Republican members of the United States House of Representatives. It is generally considered to be the most conservative and furthest-right bloc within the chamber. The caucus was formed in January 2015 by a group of conservatives and Tea Party movement members, with the aim of pushing the Republican leadership to the right. Its first chairman, Jim Jordan, described the caucus as a “smaller, more cohesive, more agile and more active” group of conservative representatives. Members of the Freedom Caucus are typically considered a part of the MAGA movement and loyalists to Donald Trump.
