If Atom A has mass number 239 and atomic number 93 and Atom B has a mass number 239 and atomic number 94 are atoms A and B of the same element and why?

No, the proton number decides, whether they are of the same element. In this case, they are isobars.

What does an element's atomic number tell us?
The atomic number is the number of protons that the element has.
What makes one atom of an element different from another?
The atomic number or z number or the number of protons is what makes one atom different from another. The atomic number or z number or the number of protons is what makes one atom different from another.
Can atoms of different elements have the same number of protons be from the same element?
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
What is the atomic number also equal to?
The atomic number is equal to the protons and electrons of an element.
How does the atomic number identify the atoms of a particular element?
The atomic number of an element is unique to that element. The atomic number is equal to the amount of electrons in one atom of that element. As each element categorically has it's own amount of electrons, you can identify an element from this number.
Do all atoms of any one element have the same atomic number?
An atomic number is actually related to an element and not an atom. Therefore, the question is not relevant. It is NOT atoms that have an atomic number; it is the element.
What is the atom that tells the number of protons in the nucleus of every atom of an element?
The atomic number of an element is the number of protons in the nuclei of its atoms. Each element has a unique atomic number.
Form a atomic number of 15 atoms?
Atomic number is the number of protons in an atom, not the number of atoms. The element with the atomic number 15 is phosphorus.
What does the atomic number of an element say about the number of particles in atoms of that element?
The atomic number is equal to the number of protons and neutrons in a neutral atom.
What are the atomic number of an element in a particle?
The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.
What is responsible for the atomic number?
The number of protons in an atom is its atomic number and it is the basic identity of the atoms of an element.
What is the name of number of protons in the atoms of an element?
The number of protons in an atom is its atomic number.
What is an atomic number and a mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The atomic mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
The atomic number determines the what?
The number of protons.
What are the atomic numbers and atomic mass?
Atomic Number :- atomic number of an element is the number of protons present in the nucleus of the atom. (since atoms are electrically neutral the number of protons in an atom is equal to the number of electrons in an atom) Atomic Mass :- atomic mass of an element is the number which tells us how many times an atom of that element is heavier than an atom of hydrogen (whose atomic weight is taken as unity [1])
What is a substance in which one or more atoms have the same number of protons or atomic number?
Element
All atom of an element have the same?
All atoms of an element have the same atomic number.
