The electrons specifically the outermost electrons determines the chemical properties. These are often called the valence electrons. The radioactivity of a particular isotope is determined by the nuclear composition in terms of protons and neutrons.
Protons. All atoms of the same element have the same number of protons in their nucleus, which defines their element and gives them their unique properties.
Minerals are comprised of one or more chemical elements. These elements are arranged in a specific atomic structure that gives each mineral its unique properties and characteristics.
Isotopes of an element have the same number of protons in their nuclei (same atomic number) but different numbers of neutrons, resulting in different mass numbers. This difference in neutron content gives each isotope unique physical properties such as stability, radioactivity, and atomic mass.
False. Most minerals are compounds, meaning they are composed of two or more elements bonded together. This is what gives minerals their unique chemical and physical properties.
Isotopes of an element have the same number of protons but differ in the number of neutrons. This gives them the same chemical properties, but different atomic masses. Isotopes also have different physical properties, such as stability and radioactive decay rates.
Mossy zinc is classified as an element because it consists of only one type of atom—zinc. In this case, the atoms are bonded together in a metallic form, which gives mossy zinc its unique physical and chemical properties.
Gold is an element because it is composed of only one type of atom, specifically gold atoms. This gives it its unique chemical properties and characteristics that define it as an element.
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.

Hydrogen
the Atomic number on Periodic Table is the identity of an element in the table , it gives the indications about Group, period and Block of elements it also predicts the chemical and physical properties of the element.
The smallest particle of an element that contains all the chemical properties of that element is an atom. Each element is made up of atoms that have a unique number of protons, defining its chemical properties.
