How do you distinguish elements?

Elements are distinguished by their atomic number, which is the number of protons in the nucleus of an atom. The element's atomic number determines its chemical properties.


What is a unique substance composed of atoms have the same atomic number?

An element is a unique substance composed of atoms with the same atomic number, meaning they have the same number of protons in their nucleus. Each element is distinguished by its atomic number, which determines its position on the periodic table and its chemical properties.


What is atomic number. How is it used to distinguish one element from another?

The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.

Is magnesium a element and why?

Yes it is an element with 12 protons.A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, the number of protons in its nucleus.


What distinguishes one element from?

An element's atomic number, or number of protons, differentiates one element from another.


How is atomic number used to tell one element from another?

The atomic number of an element stands for the number of protons in the unique atom of the element. The atomic number also is the same as the number of electrons. The atoms in each element differ from atoms in other elements by virtue of the number of positively charged protons in the atomic nucleus and the corresponding number of negatively charged electrons. The number of protons (or electrons) is the atomic number of the element. The atomic number ranges from 1 for Hydrogen to 92 for Uranium and then beyond through the transuranic elements created in laboratory conditions.


Why do protons distinguish one element from another?

Protons distinguish one lement from another because the number of protons in an element is equal to the atomic number, and each element has its own atomic number for example Hydrogen's atomic number is 1, which means it has 1 proton


How is atomic number used to distinguish one element from another?

The atomic number is the number of protons in an atom, and each element has a unique atomic number. This means that the atomic number is used to identify and distinguish one element from another. The number of protons in an atom determines its chemical properties and its placement on the periodic table.


How can you identify an element from other elements?

You can identify an element by its atomic number, which is unique to each element. Elements are also distinguished by their physical and chemical properties, such as color, density, melting point, and reactivity. The arrangement of electrons in an element's atomic structure is another key factor in identifying elements.


What is an atomic number and how is the atomic number used to distinguish one element from another?

The atomic number is equal to the number of protons in the atomic nucleus. It is an individual characteristic.


What distinguishes one element from another?

Elements are distinguished based on their unique number of protons in the nucleus, which is known as the atomic number. Elements with different atomic numbers will have different chemical properties and behaviors. Additionally, elements can have different numbers of neutrons in their nuclei, creating isotopes of the same element.
