How do you find the number of proton and atomic number in the mass number 75?

You have to know the element with the mass number of 75. Then you would look it up on the Periodic Table to find the atomic number, which is the number of protons.

What is the formula for the atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
What type of particle has an atomic number of 1 and a mass number of 1?
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.
What does the atomic mass subtracting the number of protons equal?
Atomic Mass - Proton Number = Number if Neutrons (probably an isotope)
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.

Is the proton number the same as the atomic mass?
yes
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
How do you find the number of particles in a compound when given the mass?
The mass is the number of particles. Especially with atoms on the periodic table. The atomic mass is the number of proton and neutrons in the nucleus.
What is the formula for atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
How do you calculate the number of proton neutron and electron using atomic no and mass no?
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
What happen to atomic number and mass number of nucleus when it emits alpha particle electron and proton?
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
Atomic number is equaled to what on the periodic table?
Atomic number is the bottom number on an element in the periodic table. It is the proton number, so tells you how much protons are in an element. EXTRA: you can find the neutron number by subtracting the mass number from the proton number.
The diffirentiate of atomic mass and atomic number?
Atomic mass is defined as the sum of the no. of proton and neutron present in the nucleus of an atom and Atomic Number is defined as the no. of electrons present in the extra nuclear part of an atom . BY; SHUBHAM KAKKAR
