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.
hi, was hoping to find some equations or method to find the force needed to break the bonds of a cell that is attched to a surface. I have the force that the cell is bonded with and therefor the force needed to overcome to detach the cell. however it is the overcoming force i need to find. The...
hi all,
I have read papers in which they specify the dangling bonds on the surfaces and tey saturate it with hydrogen forexample;
1. should it be hydrogen atoms or ghost hydrogen?
2. how to specify the dangling bonds?
3. any suggestion for specifying the position of these hydrogens in...
in chemistry, how do i know when there is an ionic bond and when a covalent bond, someone told me when the difference between two atoms electronegativity is more than 2.5 there is an ionic bond, but there are molecules with differences in its atoms electroegativity less than 2.5m such as MgO or NaCl
Bond Enthalpies..please help!
Got the first one, but can't figure out how to do "b" and "c." Not understand which ones make/break.

I need to identify two repulsive forces and two attractive forces that influence the formation of chemical bonds between two atoms.

To start off with I am only a layman in the subject, in actual fact I've just finished my GCSE year. Please forgive me if I have misinterpreted any area. To this end, my question is whether particles/molecules that are not moving are affected by gravity? Using Einstein's theory of gravity as...
I have thought of two possible explanations:
a) Energy required to break H bonds = Energy released when H bonds form.
There is a "constant" equilibrium in the system, meaning, some water molecules form H bonds, releasing energy to the environment which causes other water molecules to loose...

Hi,
what is the best method or algorithm or where could I find information for, given a certain molecule, know what bonds are not rigid ? For instance in Ph-CH2-Ph, the CH2 carbon would you consider as rigid or as flexible ?
Thanks
i am doing revision for my exams aand was wondering which one of these, high temperature, hydrolysis or pH change would break the ionic bond between amino acids.
I would go for pH change. I have no reason, it's just instinctively.

From what I gather both ionic and covalent bonds transform all the elements involved into ions. Does that mean every chemical compound that exists consists of ions and not atoms or are there chemical compounds that are made of pure unionized atoms?
Also when they speak of ionized water what...

Do coordinate covalent bonds have to involve the sharing of a PAIR of electrons or can it just be a single electron?
Example: XeF4
Now, since Xe already has a full octet, it would seem correct that the F basically shares electrons to Xe without donating any as well. This would only be true...

What determines the ionic nature of a bond? I am a bit confused regarding this.
Is it the polarising ability of the cation or the greater electronegativity of the anion? Regarding fajan's rules, smaller the size of the cation (and greater the charge) and smaller the size of the anion, greater...
Figuring sum of double bonds and rings ??
Does anyone know how if there is a way to figure out the sum of double bonds and rings of a compound C6H9BrO ?? Lost.. thank you.
I seemed to be confuse when to use double and triple bonds. For example, take CH2O and HCN. How do you know if you can use a triple or a double bond on the carbon and oxygen for CH2O? I know the correct answer is a double bond, with two lone pairs on the oxygen. And for HCN, it is a triple bond...
Hey there,

Now obviously, ionic bonds are "weaker" than covalent bonds, but my question is that according to the attached image, you can't necessarily have crystals being formed in a covelant bond as you would in an ionic bond, right? And also, when an ionic bond occurs, what makes it possible for a...

ok so 20 degrees celcius water, then you cool it. density increases until 4 degrees. if u cool it more, density decreases.
Why is that?
does it have to do with the type on polar bonds water has?
