What determines the chemical properties of an atom?

These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties. read more

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. The atomic mass is the mass of an atom presented as atomic mass units. read more

The number and arrangement of the electrons in an atom is what determines the chemical properties of an atom. Chemical properties of an atom, element, or compound can be observed when a chemical change occurs, and the electrons surrounding an atom can help form chemical bonds with other atoms. read more
