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 else can I help you with?
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 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.
What is the atomic number and atomic mass for hydrogen?
Each isotope of each element has an atomic mass number. The atomic mass numbers for hydrogen are 1, 2 and 3. That's because hydrogen has three isotopes. "Regular" hydrogen has a single proton in its nucleus. It's atomic mass is 1. There is also heavy hydrogen, which has a neutron bound to the proton in its nucleus. It's atomic mass is 2. Heavy heavy hydrogen has two neutrons bound together with the proton. It's atomic mass is 3. A link is provided to the Wikipedia article on hydrogen.

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.
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.

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.
What is atomic number or atomic mass?
ATOMIC MASS ;The total numbers of protons and neutrons present in the nucleus of an atom is called atomic mass and it is represented by A ATOMIC NUMBER;the number of protons in the nucleus of an atom are called atomic number or proton number and it is represented by Z
An atom has an atomic mass of 101g and has 57 neutrons what is the atomic number?
If an atom has an atomic mass of 101g and 57 neutrons, then:Atomic Mass = (number of protions) + (number of neutrons) 101 = (X) + (57) or.... (101) - (57) = x 101-57=44 the element that has 44 as its atomic number would be RutheniumAs we know mass of atom is primaril constituted by the neutrons and protons,while the mass of electron is neglegible.Taking mass of proton equal to mass of neutron and both having a unit mass.we can say that mass of an atom is equal to the number of protons and neutrons multiplied with the mass of i proton/neutron.we are given mass of lithium =7=>(no. of neutron + no. of protons)*(mass of 1 proton/neutron)=7=>no. of neutrons + no. of protons *(1)=7=>no. of neutrons=7-no. of protons=>no. of neutrons=7-3 (atomic no=no. of protons)=>no. of neutrons=4
What is the atomic mass of a proton?
The atomic mass of a proton is approximately 1 atomic mass unit (u) since protons have a mass of around 1.007 atomic mass units.
What is the number of proton on oxygen element?
8. with an atomic mass of 15.9994
