what are the chemical properties of an element
The chemical properties of an element are due to thedistribution of electrons around the atom’s nucleus, particularly the outer, or valence, electrons; it is these electrons that are involved in chemical reactions. A chemical reaction does not affect the atomic nucleus; the atomic number therefore remains unchanged in a chemical reaction.

What are chemical properties of elements in the periodic table?
Chemical properties of elements in the periodic table include atomic number, atomic mass and electronegativity. The atomic number refers to the number of protons contained in the core of an atom.
What are the chemical properties of atoms of the same element?
Chemical properties. Then atoms that have the same atomic number may differ in atomic mass. Atoms of the same element that differ in atomic mass are called isotopes. Mainly with the heavier atoms that have a higher atomic number, the number of neutrons within the core may exceed the number of protons.
What is the importance of chemical properties?
Chemical properties. The relative occurrence of the isotopes in nature is an important factor in the determination of the overall atomic mass of an element. In reference to a certain chemical element, the atomic mass as shown in the periodic table is the average atomic mass of all the chemical element’s stable isotopes.
What are some examples of chemical properties?
Chemical properties include things like reactivity to oxygen, flammability, and ability to hold on to electrons during a chemical reaction. The periodic table is a table that organizes elements based on their atomic number and properties. There are three main categories of elements found on the periodic table:
