- Ionic compound (Wikipedia)
In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions. These can be simple ions such as the sodium (Na+) and chloride (Cl−) in sodium chloride, or polyatomic species such as the ammonium and carbonate ions in ammonium carbonate. Individual ions within an ionic compound usually have multiple nearest neighbours, so are not considered to be part of molecules, but instead part of a continuous three-dimensional network. Ionic compounds usually form crystalline structures when solid.
- January 6 United States Capitol attack (Wikipedia)
On January 6, 2021, the United States Capitol Building in Washington, D.C., was attacked by a mob of supporters of then-U.S. president Donald Trump, two months after his defeat in the 2020 presidential election. They sought to keep Trump in power by occupying the Capitol and preventing a joint session of Congress counting the Electoral College votes to formalize the victory of President-elect Joe Biden. The attack was ultimately unsuccessful in preventing the certification of the election results. According to the House select committee investigating the incident, the attack was the culmination of a seven-part plan by Trump to overturn the election.
