What is the difference between atomic size and atomic number?

Answer 1

The atomic number of an element determines the number of protons that are present in that element. The atomic size refers to the distance that the outermost valence electrons are from the nucleus.

Answer 2

Atomic size refers to the physical size of an atom, usually measured as the distance from the nucleus to the outer electron shell. Atomic number, on the other hand, is the number of protons in the nucleus of an atom, which determines its chemical properties and its place on the Periodic Table.

Answer 3

Atomic size increases along with atomic number from top to bottom in a single column of a periodic table. Across a row of a periodic table, size is more likely to decrease with increasing atomic number.

Answer 4

no difference. atomic number is the number of protons in an element. Atomic Mass is the total mass of protons, neutrons, and electrons in a single atom of the element.

Answer 5

atomic number represents the protons. mass number represents protons and neutrons.
