That number is named after the Physicist Ernst Waldfried Josef Wenzel Mach,
an Austrian physicist and philosopher. In German, his name is pronounced 'mock'.
Among other subjects, he studied sound in air, and the structure of shock waves.
It's often useful to talk about "How many times the speed of sound are we moving ?"
and that's the number named for Mach. For example, a speed of "Mach 2.1" is
2.1 times the speed of sound in the air that the object is moving through.
This is actually Mach speed. One Mach speed unit is the speed of sound in air. Obviously a very rough unit.
The other scientists would mock and criticize him. Accuse him of being an American hold-out.
add the number of nucleus and proton number
To find the number of neutrons in an atom you would subtract the protons from the atomic mass. The number of protons is equal to the atomic number. When dealing with an element with no net charge, the atomic number = the number of protons and also the number of electrons. The atomic mass - the atomic number (number of protons and electrons) = the number of neutrons
In a neutral atom, the number of electrons will be the same as the number of protons. This is because one positive proton will cancel out one negative electron; therefore, if the atom is neutral, it must have the same number of protons and electrons.The number of protons is also the same as the atomic number. For this example, Bromine, with the atomic number of 35, has 35 protons.Bromine:Atomic number- 35Number of protons- 35Number of electrons- 35The mass number is the sum of the atomic number (or number of protons/electrons) and the neutrons. For this example, we know the atomic number (35) + # neutrons = mass number (80). To figure out the number of neutrons, take the mass number and subtract the number of electrons/protons/atomic number. Mass number (80) - atomic number (35) = neutrons (45).
This means to be disappointed and to mock at the same time.
