The Atomic Mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.
The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.

What subatomic particle is related the atomic number of an element?
protons, no. of protons is equal to the atomic number of an element.
What two elements make up the atomic number?
All the elements have an atomic number. The atomic number is the number of protons found in the atom of a certain element. And to equalize themselves the atoms will usually have the same amount of electrons as protons so electrons also equal the atomic number. The atomic number is the number on the top of the box on the periodic table for each element. You must have been asking what two subatomic particles make up the atomic number. In that case it would be the proton and the electron because the neutron is so mall that chemist's usually nullify it.
How many protons and electrons are in element with an atomic number?
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
What is uraniums atomic number?
Uranium is a radioactive element. It is in the f block. We use it for make energy.
What makes up the atoms mass number?
The mass number is the average total of the number of protons and neutrons in the atomic nuclei of all the isotopes of that element on earth. Thus, the average number of neutrons in that element can be found by subtracting the atomic number from the mass number.
What particles make up the atomic number of an element?
The number of protons
What particles make up the atomic number on a periodic table?
the number of protons make up the atomic number
What subatomic particle is related the atomic number of an element?
protons, no. of protons is equal to the atomic number of an element.
What is the maximum number of covalent bonds an element with atomic number 7 can make with an element with atomic number of 16?
An element with atomic number 7 (nitrogen) can make a maximum of 3 covalent bonds, while an element with atomic number 16 (sulfur) can make a maximum of 2 covalent bonds. Therefore, when they combine, they can form a total of 5 covalent bonds between them.
The smallest part of an element that act like an element?
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.

Has an atomic number of 7?
Could you please re-ask your question in a better manner, because that question does not make sense. Are you trying to ask the atomic mass of the element with the atomic number of 7? or are you just stating that there is an element with the atomic number of 7? because that is not a very good question.
What are the particles that make a atom including the atomic number and mass number?
The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom
What is uraniums atomic number?
Uranium is a radioactive element. It is in the f block. We use it for make energy.
Definitions of sub atomic particles?
Sub-atomic particles are even smaller particles that make make an atom
