What determines an atoms chemical properties?
The chemical behavior of an atom depends mostly on the number of electrons in its outermost shell.
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has in it atoms from the elements used in the formation. The atoms in the molecule are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed. It is the electronic…
The nucleus of an atom (protons and neutrons) determines if an atom is radioactive. The tendency is, the larger the nucleus, the more unstable it is and the more likely it is to be radioactive. As for the chemical bonding properties of the atom, the electron configuration determines how it will bond, with what it will bond, and in what ratio atoms will bond to form the 20,000,000 different substances on Earth.
A substance that is formed from atoms with a characteristic set of physical and chemical properties is called what?
An isotope can be thought of as a subtype of an element. All atoms of an element have the same number of protons - that's what mainly determines their chemical properties. Atoms which have the same number of protons but a different number of neutrons are said to be different isotopes of the same element.
