which of the following defines an element

Sagot :

Answer:

An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.

Answer:

Each element has unique physical properties such as density, melting point, boiling point, etc. These properties can be used to identify an element using a reference book that contains such information about each element. Flame tests, atomic spectra, and spectroscopy can be used to identify some elements.
