WebJun 4, 2024 · The atomic number defines the identity of an element. It describes the number of protons in the nucleus. In an electrically neutral atom, the number of protons equals the number of electrons. Isotopes of an element have the same number of protons but have different numbers of neutrons in their nuclei. WebWhat particle numbers determine the identity of an element? How many naturally occurring elements are there? How is the periodic table organized? The amount of protons determines the chemical nature of an atom and if all atoms have the same number of protons with the same chemical and physical properties, collectively they constitute an element.

WebThe number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element: Its value determines the identity of the atom. For example, … WebSep 9, 2005 · Hello Sam: As you probably know, an atom of an element starts out electrically neutral, i.e., the number of electrons (each carrying a "-1" electric charge) equals the number of protons (each carrying a "+1" charge) in the nucleus. When atoms take part in chemical reactions, two possibilities occur. WebSep 20, 2010 · Best Answer. Copy.
