What is the modern definition of atomic number?

In the modern periodic table, the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).

What is atomic number short answer?

atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

How is atomic number calculated?

1 Atomic number is the number of protons so the answer is 10. 2 It is also the number of electrons because, elements have no overall charge as the positive protons cancel out the negative electrons. Therefore, if the question only gives the number of electrons, you write the number of electrons as the answer.
