Neither, except for the anomalous hydrogen-1 isotope. The atomic mass number of an atom is the sum of the numbers of protons and neutrons in the atom. If the questioner meant "atomic number" instead of "Atomic Mass number", the atomic number is fundamentally the number of protons, but if the atoms is neutral, the numbers of protons and electrons are the same.
What else can I help you with?
What is the relationship between the atomic number and the electrons in neutral atom?
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
What do you notice about the atomic number and the total number of electrons in an atom of that element?
The atomic number is equal to the number of protons in an atom, which also corresponds to the number of electrons in a neutral atom. This means that the atomic number gives you the total number of electrons in a neutral atom of that element.
Does the number of electrons in an atom give its atomic number?
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
Does number of electrons in an atom give it atomic number?
Yes, the number of electrons in an atom is equal to its atomic number. The atomic number is the number of protons in the nucleus of an atom, and since atoms are electrically neutral, they have the same number of electrons.
Where did you found in an element number of protons and electrons?
The atomic number is equal to the number of protons and electrons, for a neutral atom.
What indicates the number of an electron in a neutral atom?
The number of an electron in a neutral atom is indicated by the atomic number, which is equal to the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is the same as the number of protons.
In a neutral atom the atomic number tells us the numbers of protons and?
In a neutral atom, the atomic number tells us the number of protons in the nucleus. Since the atom is neutral, the number of protons is equal to the number of electrons orbiting the nucleus.
An element has an atomic number of 30 how many protons and electrons are in a neutral atom of the element?
It will have 30 protons and 30 electrons if the atom is neutral.
Nobelium has an atomic number of 102 how many protons and electrons does it have?
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
What identify the number of protons neutrons and electrons in the atom.?
The number of protons in an atom is equal to its atomic number, which identifies the element. Neutrons are found by subtracting the atomic number from the mass number. For a neutral atom, the number of electrons is equal to the number of protons.
What does the atomic number determmine?
Atomic number is the number of protons in the nuclei of the atoms of an element. It is the number of protons that determines the atomic number. In a neutral atom, the number of electrons equals the number of protons. So in a way you could say that atomic number determines the number of electrons in a neutral atom.
What does the atomic number tell you the number of in a neutral atom of an element?
The atomic number of an element is the number of protons in each atom of the element, whether neutral or not. If the atom is neutral, the number of electrons in the atom is the same as the number of protons.
