Bonds Definition and 203 Threads

Barry Lamar Bonds (born July 24, 1964) is an American former professional baseball left fielder who played 22 seasons in Major League Baseball (MLB) with the Pittsburgh Pirates and San Francisco Giants. He received a record seven NL MVP awards, eight Gold Glove awards, a record 12 Silver Slugger awards, and 14 All-Star selections. He is considered to be one of the greatest baseball players of all time.Bonds holds many MLB hitting records, including most career home runs (762), most home runs in a single season (73, set in 2001) and most career walks. He led MLB in on-base plus slugging six times, and placed within the top five hitters in 12 of his 17 qualifying seasons.Bonds, an all-around baseball player, won eight Gold Glove awards for his defensive play in the outfield. He stole 514 bases, becoming the first and only MLB player to date with at least 500 home runs and 500 stolen bases (no other player has even 400 of each). He is ranked second in career Wins Above Replacement among all major league position players by both Fangraphs and Baseball-Reference.com, behind only Babe Ruth.However, Bonds led a controversial career, notably as a central figure in baseball's steroids scandal. In 2007, he was indicted on charges of perjury and obstruction of justice for allegedly lying to the grand jury during the federal government's investigation of BALCO. The perjury charges against Bonds were dropped and an initial obstruction of justice conviction was overturned in 2015.Bonds became eligible for the National Baseball Hall of Fame in 2013; he has not received the 75% of the vote needed to be elected, with his highest share of the vote coming in 2021 balloting, his 9th of 10 years of eligibility, when he received 61.8%. Some voters of the Baseball Writers' Association of America (BBWAA) have stated that they did not vote for Bonds because they believe he used performance-enhancing drugs.

    Diamond oxidation -- covalent bonds

    In order for a diamond to oxidize, do the covalent bonds have to be broken? What would happen if I put the diamond in an oven heated to 150 degrees Celcius? Would the reaction start and after some time the stone would disappear?

    I Covalent Bonds -- Which type of force?

    When you study physics deeper you learn there are 4 types of atomic forces that represent all other in the atomic level (i.e. electromagnetic force, gravitational force, strong nuclear force, weak nuclear force). I always try to see how they manifest in the the atomic interactions. For example...

    B What happens when ethane absorbs UV light?

    Because when I have two carbon atoms, they create a single bond, so their two electrons are in one boding orbital, but I have also one anti-bonding orbital here. And when the electron excitates from ##\sigma## to ##\sigma^*##, how can the bond between the carbon atoms exist? It has to disappear...

    Solubility depends on polarity or on the number of hydrogen bonds?

    Does solubility depend on the polarity of the molecule or on the number of hydrogen bonds that are formed with water? For example: CF4 can form hydrogen bonds, but it's not polar. Glucose Is Polar e can form hydrogen bonds. How can I predict solubility? Thanks

    Non polar molecule with polar bonds?

    Consider for example Carbon Dioxide. Oxygen is more electronegative than carbon so should obtain the "lion's share" of the paired electrons in the double bonds. But (as I see it anyway) the oxygen atoms on either side of the central carbon "assist" the carbon atom to maintain an even share of...

    I Why does doping make resonating valence bonds (singlet pairs) mobile?

    I know in RVB theory that neighbouring Copper atoms form singlet pairs via the superexchange "force". Upon doping with holes, these neutral singlet RVB pairs become mobile and charged and are able to superconduct. I know that the resonating valence bonds are in the copper 3d(x^2-y^2) orbital and...

    Why Do Atoms Need to Have Free Electrons to Create Covalent Bonds?

    Atoms bond because compounds are more stable or have less energy than individual atoms. Interatomic potential energy depends with distance of atoms and there is a distance at which potential energy has minimum. This distance is a length of the bond. When forming covalent bonds, why is it...

    Ionic bonding question about "double" ionic bonds
