...and the number of electrons.
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.
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.
The number of protons is identical to the number of electrons when an atom is in a neutral state.
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
A neutral atom has the same number of electrons as it does protons. The atomic numbers on the periodic table for each element are the number of protons. So, look up the element on the periodic table, note its atomic number, and you will then know the number of protons and electrons in a neutral atom of that element. For example, magnesium (Mg) has atomic number 12. So a neutral Mg atom would have 12 protons and 12 electrons.
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.
The numbers of each are equal! Therefore the atom is neutral.
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.
The number of protons and electrons in a neutral atom are the same and given by the element's 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.
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.
The atomic number is the number of protons and therefore, assuming the atom is neutral, the number of electrons. You would need to additionally know the atomic mass to figure out the number of neutrons.
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.
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.
The number of protons is identical to the number of electrons when an atom is in a neutral state.
Atomic number is the number of protons in a neutral atom
atomic number = number of protons = number of electrons (in a neutral atom)
