Argon, it ha 18 electrons.
In a neutral atom, the number of electrons is always the same as the atomic number.
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.
Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons
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 electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number. The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number.

Yes, the number of electrons in a neutral atom is equal to the atomic number.
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.
Atomic number is 6. The isotope is 6C11 Atomic number = number of protons = number of electrons (for a neutral atom)
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.

For neutral atoms the atomic number is equal to the number of electrons.
Look up the atomic number of the element. The atomic number is the number of protons, in a neutral atom this is the same as the number of electrons.
Always the Atomic Number = Number of Protons If electrically neutral, Atomic Number = Number of Electrons = Number of Protons
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.
