Chapman was hit in the head by a pitch thrown by Yankees pitcher Carl Mays, and died 12 hours later. He remains the only Major League Baseball player to have died from an injury received during an MLB game. His death led to Major League Baseball establishing a rule requiring umpires to replace the ball whenever it became dirty, and it was partially the reason--along with sanitary concerns--that the spitball was banned after the 1920 season. Chapman's death was also one of the examples used to emphasize the need for wearing batting helmets (although the rule was not adopted until over 30 years later).

has any baseball player ever died on the field?

A: no

The mass number (symbol A, from the German word Atomgewichte (atomic weight), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It determines the atomic mass of atoms. Because protons and neutrons both are baryons, the mass number A is identical with the baryon number B as of the nucleus as of the whole atom or ion. The mass number is different for each different isotope of a chemical element. This is not the same as the atomic number (Z) which denotes the number of protons in a nucleus, and thus uniquely identifies an element. Hence, the difference between the mass number and the atomic number gives the number of neutrons (N) in a given nucleus: N = A Z (\displaystyle N=A-Z) .

is the mass number the same as protons?

A: no

The worldwide Mars bar differs from that sold in the US. The American version was discontinued in 2002 and was replaced with the slightly different Snickers Almond featuring nougat, almonds, and a milk chocolate coating. Unlike the American Mars bar, however, Snickers Almond also contains caramel. The US version of the Mars bar was relaunched in January 2010 and was initially being sold on an exclusive basis through Walmart stores. The European version of the Mars bar is also sold in some United States grocery stores. The US version was once again discontinued at the end of 2011. In September 2017, Ethel M Chocolates, a gourmet chocolate subsidiary of Mars, Inc. launched the 'original American recipe' of the Mars Bar in their stores and on Amazon.com.
