Neutral atoms of argon (atomic number 18) have 18 electrons. Consequently, they do not have the same number of electrons as hydrogen (1 electron), helium (2 electrons), or lithium (3 electrons).
Except for ions, the number of electrons in an atom are equal to the number of protons. The atomic number will tell you the number of protons, and consequently the number of electrons in an electrically neutral atom. In the case of an ion, adjust the number by the indicated charge; for example Na+1 will have 11 (the atomic number of Na) - 1 (since electrons have a negative charge, you subtract the charge) = 10 electrons.
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
Electrovalent bonds
Atoms with equal numbers of electrons and protons are electrically neutral, meaning they have a charge of zero. This balance of positive protons and negative electrons cancels out any overall charge in the atom.
The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons. on a Periodic Table it is usually on top of the elemental abbreviation
Neutral atoms of neon have the same number of electrons as atoms of fluorine, magnesium, and sodium, excluding helium atoms.
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 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.
Except for ions, the number of electrons in an atom are equal to the number of protons. The atomic number will tell you the number of protons, and consequently the number of electrons in an electrically neutral atom.

The number of protons plus the number of electrons isn't a recognized figure in chemistry. The number of protons is the atomic number of an element. The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons. The number of protons plus the number of neutrons is the atomic weight of an element.
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
Often by the atomic number except for ions.
An atom has no electrical charge because the negative charge of the electrons counteract the positive charge of the protons and the neutrons in the nucleus have a neutral charge. For example, Carbon has 6 electrons(-6 charge) and has 6 protons(+6 charge). Giving it an atomic weight of 12 and a charge of 0. The 6 neutrons do not change this charge, they keep it the same because they are neutral. (:
13. Both have same charge except electron has negative and proton positive. Neutrons are electrically neutral
if number of electron and protons are equal(except for H,as it has no proton,so it shoulh has one electron to be electrically neutral).
Atoms gain or lose electrons so they have the same amount of electrons as the nearest noble gas. If you came across this question in the Science 10 textbook, page 39, the answer is found on page 35, bottom paragraph, 4 sentences in. I do have to say the question isn't well written.
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
