What is an atomic number in science?

An atomic number is the number of protons found in the nucleus of an atom. It determines which element an atom belongs to and is unique for each element on the periodic table.

What Atomic Number represents?

The atomic number equals the number of protons in an atom, as well as the number of electrons in a stable, electrically neutral atom, it represents the identity of an element ,the simplest form of matter.

The atomic number of an atom or element describes the number of what?

The atomic number of an atom is also known as the proton number. it is, quite simply, the number of protons in the atoms nucleus - as an atom needs to be equally charged, it is also the number of electrons in an atom however, if an atom is radioactive this is not always true.

Atomic number equals the number of?

The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
