What Is the Life Span of the Common Cat? A strong genetic background for longevity can't be discounted. Given proper care, nutrition, and regular veterinary visits, a cat kept indoors can live as long as 21 years or more. (The average age of cats is 12-15 years) This is, of course, barring any serious medical conditions or untimely accidents.
Compound: two or more different atoms bonded together. Mixture: two or more different atoms together but not joined. Molecule: two particles (same or different) bonded together. Element: only 1 type of atom; this definition is applied to things both bonded and not to itself.f one atom, then not molecule and not mixture and not compound. If two atoms and same element, then molecule and not compound and not mixture. If two atoms and not same element, then compound and molecule and not mixture.
Atoms have the  same number of protons and electrons, â¦ because otherwise, you would  have an ion.   A molecule consists of two or more atoms bonded together.    Atoms are single units of elements.   Molecules are agglomerations of two or more atoms  (of the same or different elements). A molecule is the smallest  particle of a chemical compound. Molecules are formed by atoms in a  multitude of different arrangements.   - Most atmospheric oxygen forms diatomic molecules (O2),  but also ozone (O3)   - One molecule of water has one atom of hydrogen and two atoms of  oxygen. So-called heavy water contains deuterium, which is hydrogen  that has neutrons.
