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

∙ 7y agoThe atomic number is equal to the number of protons in the nucleus, and for neutral atoms, it is the same as the number of electrons.
Every element has a unique atomic number, and so each element's identity is determined by the number of protons in its nucleus.
However, the same element have have different numbers of neutrons in its nucleus. Two atoms of the same element with two different numbers of neutrons in the nucleus are isotopes. Also, note that if an atom is not charged (neutral), than the number of protons must equal the number of electrons, and so the atomic number is also equal to the number of electrons in a neutral atom of each element.
However, if the atom is charged (and therefore called an ion), it will have a different number of electrons orbiting it. If the number of electrons is less than the number of protons, it will be a positively charged ion, and the charge will equal the difference between the number of electrons and protons. The same is true if it has more electrons than protons, except now the charge will be negative. Look under the Web Links to the left of this answer for a periodic table. The number listed for each element is its atomic number.
The atomic number of an element is the number of protons and electrons an atom of it has. For example, Hydrogen has an atomic number of 1, and it has 1 proton and 1 neutron. Oxygen is number 8, and it has 8 protons and 8 electrons. The number of neutrons it has doesn't affect it.

∙ 11y agoThe 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.

∙ 13y agoThe atomic number of any given element represents how many protons are in the nucleus. Assuming the atom has no charge, the number of protons will equal the number of electrons on the outside of the nucleus.
The atomic mass is the number of protons AND neutrons in the nucleus.
