What is the atomic number of an element based on?

Answer 1

Caleb Adams

The number of protons a single atom contains in its nucleus in a neutral charge.

The quantity of protons in the nucleus of an individual atom that results in a neutral charge.

The number of protons and electrons must be equal for something to be neutral.

The atomic number of an element is the number of protons in the nuclei of its atoms.

The atomic number of an element is the number of protons in the nuclei of its atoms. The atomic number is different for each element and determines the identity of an element. The elements are arranged in order of increasing atomic number on the periodic table. The atomic number of an element never changes during a physical or chemical change, but it can change during a nuclear reaction, in which case the element also changes. So far, there are #118# elements known, with atomic numbers from #1-118#. In a neutral atom , the atomic number is equal to the number of electrons.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
